Select Empty Connection 1 from the Probe Description area. Five empty connections appear in the Probe Description area. The probe drawing shows this:. Assign the appropriate tips and or extensions needed for each Empty Connection until you have up to five total tips, such as shown here:.

You don't have to fill all five connections. The tip assigned to Empty Connection 1 points in the same direction as the rail on which it rests. This is the Zdirection. The tip assigned to Empty Connection 4 points in the X- direction. The tip assigned to Empty Connection 5 points in the Y- direction. Click OK to save your changes or Measure to calibrate the probe. See "Calibrating Probe Tips" for information on calibrating tips. The probe drawing displays something like this:.

For each of the four Empty Connection items in the Probe Description area, select same probe tips four times, once per each horizontal tip. On probe configurations that contain multiple probe shanks and tips like the one shown below, PC-DMIS provides a way for you to easily know which tip is the active tip at any given time.

Setting Up and Using Probes With version 4. Similar to highlighting the active probe tip, you can also hide all non-active probe tips on your star probe so that only the current probe tip is visible. You do this by selecting the Draw active tip only check box located on the Edit Probe Component dialog box. To show only the current probe tip: 1. The Probe Utilities dialog box appears.

Double-click on the probe head component in the Probe Description area. The Edit Probe Component dialog box appears. Select the Draw active tip only check box. Draw active tip only check box in the Edit Probe Component dialog box 4. Click OK on this dialog box and on the Probe Utilities dialog box. Now when the part program executes a tip command, any non-active tips will be hidden from view. A hard probe does not behave this way. Instead, a hard probe registers a hit whenever you press a button on the machine or arm or, in the case of scanning, when certain conditions are met such as crossing a predefined zone, elapsed time, elapsed distance, and so forth.

If you are using this type of probe, consult the "PC-DMIS Portable" documentation for information on calibrating and using this probe type. You cannot execute your part program and measure your part until the probe tips are calibrated. The terms "calibrate" and "qualify" are used interchangeably. To begin the calibration process: 1. Select the probe tip or tips you want to calibrate from the list.

Click the Measure button. The Measure Probe dialog appears. Note: If you have a probe changer and the currently active probe file is not the probe configuration in the probe head, PC-DMIS automatically drops off the currently loaded probe configuration and picks up the needed one. The Measure Probe dialog box displays a variety of settings applicable to measurement for the purpose of probe qualification. Once the desired selections are made, click the Measure button to begin.

Requirements Prior to Calibration In order to begin the calibrating process, a qualification tool must be defined. You can use the Add Tool Once Calibration Starts. Yes No Qualification Tool Moved Dialog Box This dialog box appears if your measuring machine and probe configuration support the ability to locate the qualification tool using DCC hits: Qualification Tool Moved Has the qualification tool been moved or has the machine zero point changed? For a small position change where the last known position is very cloe to the current position, it may be possible to located the tool in DCC mode without needing a Manual hit.

For a newly defined tool or a significant position change, a Manual hit will be needed to locate it. If you select Yes or Yes manual hit to locate tool , PC-DMIS displays the Execution dialog box and requires you to take 1 or more hits in Manual mode depending on the tool type before continuing the calibration process.

You may use this option when you have repositioned the qualification tool to nearly the same previous location. If you select No, PC-DMIS also displays the Execution dialog box, but it does not require any manual hits unless they are appropriate for the selected measurement method such as operating in Manual mode. Once the measurement finishes, PC-DMIS calculates the qualification results as appropriate for the type of probe, the tool used, and the operation requested. The difference between the two Yes options in the Qualification Tool Moved dialog box only affects whether or not a manual hit is needed during measurement.

For purposes of the post-measurement calculations, both Yes options are equivalent. Following calibration, a brief summary for each tip is visible in the Active Tip List in the Probe Utilities dialog box. You can also see detailed results of the calibration by clicking the Results button on that dialog box. Be sure to perform a recalibration if anything changes with your probe. The default number of Hits is 5. It remains at the Touch Speed until the hit is taken and the distance is reached again.

Note: Some controllers do not retract on their own. In these cases, PC-DMIS issues the move to do the retract, and the distance is based on ball surface to the part's theoretical hit location.

If the controller does do the retract, the distance may be calculated either from the ball surface or the ball center to either the theoretical or measured hit location, depending on the particular controller. Note: The number in the Move Speed box can contain no more than four decimal places. Note: The number in the Touch Speed box can contain no more than four decimal places. The system modes used for calibrating probes include the following: Manual mode requires you to take all hits manually even if the CMM has DCC capability.

In that case, you must take the first hit manually. This mode helps with calibrating odd probe configurations that aren't easy to model. In most cases ManDCC behaves like DCC mode with the following differences: You must always take the first hit manually for each tip, even if the qualification tool hasn't moved.

All remaining hits for that tip will then be taken automatically in DCC mode. None of the pre-measurement clearance moves for each tip are performed since all first hits are performed manually. Once PC-DMIS completes the sphere measurement for a given tip, depending on the type of wrist you have, it may or may not perform the final retract moves. It proceeds without prompting you thereby ensuring that the probe has sufficient clearance to move to the next tip's AB angles, and to perform the next AB move.

You may find this mode useful if you want to fully automate the calibration process. The Type of Operation area allows you to select the operation that will be performed when you click the Measure button on the Measure Probe dialog box. The available operations include: Calibrate Tips: This option is used to do a standard calibration of all marked tips.

Calibrate the Unit: The Calibrate the Unit option creates error maps for both infinite wrist devices and indexable wrist devices.

For indexable wrist devices see the information below in this topic. Important: This option only functions with single arm configurations. A special probe configuration, consisting of three styli of the same diameter, is placed in the probe head and as many tip orientations all possible orientations is best that the user desires are measured with this probe configuration. Generally, you should arrange the styli in a T configuration at least 20mm tall and 40mm wide like a star probe with styli at 20mm from the center.

The farther the styli are separated, the more accurate the error map will be. Once you have measured all possible orientations using the special configuration, you will be able to change probe configurations without having to do a calibration of the entire tip list. Each of the orientations measured in the original map will now automatically be calibrated in the new configuration.

Note: This option, as discussed here, refers exclusively to probe heads that have repeatable index positions such as the PH This calibration requires a 3-stylus star probe. After this calibration is performed, only the indexed positions that were qualified during the unit calibration can be used in future probe files without performing a full calibration.

The Calibrate the Unit option is not available when using an analog probe regardless of whether the probe head is of a type that is either indexable or infinite. This is because an analog probe must have each individual position calibrated to obtain the required deflection coefficients.

The exact sizes of the components may vary but the shape must remain the same. It is also best to choose the lightest components possible. Gravity can cause some error in the measurements. From the Probe Utilities dialog box, click the Add Angles button and add as many different orientations as you desire. A complete mapping of the probe head would mean measuring each possible orientation.

Select the Measure button from the Probe Utilities dialog box. The Measure Probe dialog box appears. Enter the default values to use. Select Calibrate the Unit for the type of operation to perform. From within the Measure Probe dialog box, click on the Measure button. Next, place a probe configuration that you wish to use for measurement on the probe head.

Choose at least four of the mapped orientations. Now calibrate this probe in the chosen orientations. To do this: Click Measure in the Probe Utilities dialog box. Select the Calibrate Tips option for the type of operation to perform. Click on the Measure button in the Measure Probe dialog box.

Lower Matrix: This option lets you calibrate your SP probe's lower level matrix. Qualification Check: This re-measures the tip orientations specified by the user within the selected probe file and does a comparison to the previously measured data for these tip orientations. The user can use this comparison to determine if a complete calibration is needed. This is an audit-only procedure within the selected probe file and does not update the tip offsets. For information on modifying registry entries, please view the "Modifying Registry Entries" documentation.

To enable this option you must have previously purchased the NC option. Having this option available on the portlock will enable the NC tab in the Setup Options dialog. Calibrate ScanRDV When using an analog scanning probe, some machine types support using a radius deviation from the tip's nominal size. This option button lets you easily calibrate a tip, from directly within this dialog box, for purposes of calculating a scan-specific radius deviation.

If your machine does not support the radius deviations separately from the tip size, this option button will not be available for selection. Before using this option, you must first calibrate the tip in the usual manner, typically by using the Calibrate tips option. PC-DMIS will measure a single circular scan on the equator of the calibration tool to calculate this value. Note: PC-DMIS has an older method for measuring a scan-specific deviation by using a part program containing suitable commands.

While this older procedure still functions and remains a flexible approach, it requires considerable effort to develop a suitable calibration program. The new method is likely adequate for most situations, but you can still use the previous method, as needed. The Calibration Mode area contains options allowing you to switch between the Default Mode and the User Defined options, as described below. Default Mode If the Default Mode option is selected, PC-DMIS will take the number of indicated hits around the spherical tool at either 10 or 15 degrees from the equator, plus one additional hit normal to the probe, 90 degrees from the equator.

Sample Spherical Tool Taking the hits at either 10 or 15 degrees prevents the shank of the probe from hitting the calibration sphere when the shank diameter is almost as large as the probe's tip diameter. PC-DMIS will measure the probe based on the number of levels that are entered and the starting and ending angles that are selected.

The location of the level is based on the angles that are set. Only one hit will be taken when measuring normal to the probe. Number of Levels The Number of Levels box determines the number of levels that will be used in the calibration process. PC-DMIS will divide the number of hits by the number of levels to determine how many hits will be taken at each level. Start and End Angles. The Start Angle and End Angle boxes control the location of the first and last level.

Any additional levels will be located equally between these two levels. A starting angle of 0 is located at the equator of the sphere relative to the probe.

An ending angle of 90 is located at the top of the sphere, normal to the probe. This area allows you to specify wrist positions in a pattern of up to nine sphere measurements for indexable wrist calibration. The Wrist Calibration area becomes available for selection when you meet the following conditions: Setup an infinitely indexable wrist device such as the PHS or the CW43L in the Probe Utilities dialog box. See "Defining Probes".

See the "Modifying Registry Entries" documentation. Defining AB Wrist Positions To Calibrate In order to calibrate the wrist, you need to calibrate wrist positions in a pattern of at least three A angle positions by at least three B angle positions for a total of nine sphere measurements.

The Wrist Calibration area gives you the ability to specify the angles for calibrating both the A and the B axes. The Start, End and Increment boxes allows you to specify the starting and ending angles for mapping the wrist and the increment for mapping in both the A and B axes. Note: You should choose the actual Start and End angles according to the type of wrist device you are using, the mechanical availability, and the manufacturer or vendor recommendations.

While a minimum of nine positions is required to calibrate a wrist device, you may choose to use more than this minimum. PC-DMIS will give you a slightly more accurate calibration if you use more than the minimum number of positions.

When you calibrate a wrist, you can also create a wrist error map to correct for angular errors in the wrist between calibrated positions. Control Description Create New This option button creates a new wrist error map when you click the Measure button.

Map Replace This option button replaces the closest existing wrist error map with a newly created wrist error map Closest Map when you click the Measure button. This dialog box lists any wrist error Delete Maps maps on your system; for each map, it also shows the probe's extension length, lists the number of AB angles and the angle increment value. Simply select a wrist error map and click Delete to remove a wrist error map from your system.

Shank Qualification Select the Shank Qual check box if you will be using a shank tip to take edge hits. This check box allows you to qualify the shank of the probe. Important: Be aware that if you will be using a shank probe, you only need to do a shank calibration if you'll be taking edge hits. The Parameter Sets area allows you to create, save, and use saved sets of probe calibration parameters. To create your own named parameter sets: 1.

Access the Probe Utilities dialog box. Modify any parameters on the Measure Probe dialog box. From the Parameter Sets area, type a name for the new parameter set in the Name box and click Save. You can easily delete a saved parameter set by selecting it and clicking Delete. Click the Measure button if you want to calibrate your probe tips right away. If you want to calibrate them later, click Cancel.

Clicking Cancel on this dialog box will delete any changes made to the probe file; this includes the creation of any parameter sets. This check box is disabled if the machine does not have a rotary table.

Reset Tips to Theo at Start of Calibration If you mark this check box, the tip s undergoing calibration will automatically be reset back to their original theoretical conditions when the calibration starts. This essentially functions the same as if you manually clicked the Reset Tips button in the Probe Utilities dialog box before calibration. For example, it does not affect a "Qualification Check" operation because that is only a test of the calibration and does not actually change any calibration related data.

It also does not apply when using infinite wrist devices in a mapped mode. Its main purpose is to be used with the Calibrate Tips operation when used with a fixed head, indexing wrist, or infinite wrist if used in an indexing non-mapped mode. This area lets you determine the action that PC-DMIS should take if you did not explicitly select any probe tips from the Active Tip List in the Probe Utilities dialog box prior to starting calibration.

Note that if you explicitly choose tips from the Probe Utilities dialog box, only the selected tips will be used. Note the following restrictions: This option may not achieve the desired result if you use it in a part program that has the Automatically Adjust Probe Head Wrist option enabled because the tips used in the program at the time of the calibration may change later as a result of the actual part alignment.

This option only looks at the currently open part program. It does NOT try to look through references to external files such as subroutines. If you choose the Abort execution option, PC-DMIS will abort the execution or measurement, treating the condition of no tip angles selected as an error condition. Its main purpose is to be used with the Calibrate Tips or Qualification Check operations when used with a fixed head, indexing wrist, or infinite wrist if used in an indexing non-mapped mode.

Below are some changes to the calibration procedure for SP probes made to versions 3. These entries will be created if they don't already exist the first time you run the lower matrix procedure. You shouldn't change these values unless Brown and Sharpe Engineering issues new recommendations in the future.

The following notes apply to the Upper Level Matrix calibration when using an analog type probe. Probe tab of the Parameter Settings dialog box. For versions 3. For version 3. Of course you are free to try out which algorithm works best for your particular situation. If using Trax calibration for the SP, the effective tip size generated from the calibration will differ from the design value.

If using Trax calibration for non-SP analog probes on the Wetzlar machines, the design value of the tip size is used because tip size deviation is handled differently. If using non-Trax calibration, the design value of the tip size is used. Instead, you can use the following registry items to work with your sampling hits. For information on these entries, see the "Modifying Registry Entries" documentation. When performing a discrete hit calibration of a disk stylus on an analog probe with the qualification sphere, you need to specify five hits in the Number of Hits box and two levels in the Number of Levels box in the Measure Probe dialog box.

These do not apply for probes that use the Renishaw scan-based calibration. Make sure when you define your probe, that you model a disk stylus and not a ball stylus. If your probe configuration has an additional ball stylus attached to the bottom of the disk stylus, be sure to take the hit with that ball stylus. Measuring a plane helps ensure that the hits for calibrating the face are oriented properly to reflect the actual plane of the disk.

This is the default for the traditional calibration method using discrete hits. Instead it uses the design orientation of the disk. This is the default for the Renishaw scanbased calibration.

After the hits are taken on top of the sphere it takes six hits on two levels to get a close location of the center point of the sphere. It uses the center point along with the vector from either the plane measurement or the design orientation to correctly position the subsequent measurement. For discrete hit calibration it takes five hits: four in a circular pattern around the equator of the sphere, and the fifth hit on the top, or the pole, of the sphere.

For scan-based calibration it takes a series of scans at two different levels, one slightly below the equator and one slightly above the equator. Each level is scanned in both clockwise and counter-clockwise directions. Each direction for each level is also scanned using two different scan force offsets. This results in a total of eight scans. The following procedures describe how to calibrate your SP probe's lower level and upper level matrices.

For best accuracy in the processes below, use a high quality spherical calibration tool and keep the calibration tool well cleaned throughout both calibration processes. The low level matrix contains the 3D or centered position of the probing device.

You should redo the SP low level matrix calibration at these times: Whenever you remove the probe head Whenever you remounted the probe head Whenever you attached a new SP probe Whenever the SP sustains damage During periodic intervals based on your specific needs. You must have an analog probe that utilizes a lower matrix.

You should use a rigid stylus that deflects as little as possible during the procedure. A common example of this for an SP is the 8x ceramic stylus. Calibration Procedure: 1. Ensure that the angles you need exist in the Active Tip List. From the Active Tip List select the angle used as the reference position.

In most instances this should be the angle used for the Z- direction. Unless you have a horizontal arm, this angle is usually the T1A0B0 tip. This option only appears if you're working in online mode and have the SP probe setup inside the Probe Utilities dialog box.

Select an appropriate tool from the List of Available Tools list. PC-DMIS will give a warning message telling you that if you continue you will change the machine specific parameters for the lower level matrix on the controller itself. Click Yes to continue the calibration. Setting Up and Using Probes 9.

Click Yes or No. If you're working from the Z- position, take the hit on the very top of the tool. It does this by taking: 3 hits around the sphere. This typically takes five to ten minutes to complete. PC-DMIS then presents you with nine numbers along with a message asking if these numbers are correct.

These are the lower level matrix values. If you started the calibration with the probe in the Z- direction then the ZZ value value in the third row and third column should be between about. All other values should be less than or about. If the values are correct, click OK. PC-DMIS sends an emergency stop command to the machine and then overwrites the lower level matrix values on the controller with these newer values. Press the Machine Start button on your jog box. Click OK on the message box.

Notice that the reference tip in the Active Tip List isn't calibrated. The lower level calibration doesnt calibrate the actual tip angles. Tip angles get calibrated when you perform the upper level matrix calibration procedure. Important: If you don't have a good low level matrix you will experience problems in some scanning routines and the machine may not be able to complete some scans. In addition you will experience inaccuracies.

After you've finished calibrating the lower level matrix, you can perform the regular calibration. This upper level calibration will calibrate the actual probe tips. It will also send another matrix of numbers to the controller that give small corrections to the lower level matrix based on the current probe configuration and orientation.

To achieve greater accuracy, PC-DMIS should take probe hits, measuring a full sweep, all around the equator of the calibration sphere. If you have good angle of coverage on the sphere, you will get better results. Calibration Procedure Follow this procedure to do an upper level matrix calibration: 1. Select Calibrate Tips from the Type of Operation area. Since the Default method only takes hits around the diameter and one hit on top of the calibration sphere it doesn't give a very good 3D relationship of the probe center.

Type 3 in the Number of Levels box. You can type in additional levels as long as they don't exceed the number of hits you'll be taking. But the minimum number of levels should be at least three. Type 0 in the Start Angle box. Type 90 in the End Angle box. Type 25 in the Number of Hits box. Click the Measure button when ready to begin. These numbers will automatically be correct if you've correctly followed the lower level matrix calibration procedure. The active tips are now calibrated and you're ready to program your part using the newly calibrated SP probe.

Caution: Be aware that in the Default calibration mode, calibrating tips with an A90 angle will cause the probe to crash into the shank of a calibration sphere in spheres where the shank comes out of the bottom shank vector of 0, 0, 1. This will happen because the probe tries to take a hit in the Z- position of the sphere. To fix this, use an inclined shank, don't calibrate tips that have A90 angles, or choose to use the User Defined calibration mode.

PC-DMIS supports the ability to apply temperature compensation using changeable temperature sensors or temperature sensors mounted on a CMM probe head. Continuous Contact Temperature Sensors These types of sensors are in continuous contact with the part. The temperature compensation TempComp command reads the temperature.

Changeable This sensor is a type of stylus assembly that contains a temperature sensor, and is part of the changeable probe assembly. You can place the sensor in a tool rack. It can also be attached picked up or detached dropped off in the same general manner as a stylus assembly for regular measurement. Some probe heads, such as the LSP-X5. Temperature probing, a function that automatically measures the temperature of a part, is required to measure a temperature with a non-continuous contact temperature sensor.

You must measure the temperature probing. Setting Up and Using Probes point s to measure the temperature. You can then use the TempComp command to activate the temperature compensation after you measure the temperature. To create a temperature probe file: 1. Build the temperature probe. For example: LSPX5. You do not need to calibrate a temperature probe. However, if you are using a changeable temperature sensor, you need to ensure that the theoretical vector of the temperature probe is correct.

For example, if you are using a knuckle component, you can adjust the theoretical vector by changing the rotation angle about the connection. To edit a temperature probe component: 1. The graphic below shows an example for a knuckle component. A temperature probe works similar to the way a normal probe works. The measurement starts when the sensor contacts the part. The temperature probing point can be: A measured point A vector point You must measure the temperature probing point along the vector of the temperature probe sensor.

Therefore, when you select a temperature sensor as the probe tip and measure a point, PC-DMIS drives the CMM along the vector of the active temperature probe and ignores the theoretical vector of the measured point or vector point. This action ensures that the measurement is correct and the temperature sensor properly contacts the part.

Some CMMs support only one method. Temperature is measured after a certain interval of contact with the part contact time : In this method, the sensor is kept in contact with the component for a defined time.

The temperature is measured continuously to determine the part's temperature. Most of the CMMs that support this mode have a default contact time, which is commonly referred to as a delay time. To measure the temperature with a contact time other than the default time for the CMM, you must specify the desired contact time by inserting an appropriate Assign in your PC-DMIS part program somewhere before the points that will perform the measurement.

If the time is too short, the temperature of the part may be read incorrectly. It is not necessary to have an Assign statement in the part program. This is required only if you do not want to use the default for the CMM. Temperature measured by extrapolation method: In this method, the sensor is kept in contact with the component for only a short time, and the component's temperature is extrapolated from a few measured values.

In this case, the controller controls the time for measuring the temperature. Specifying a contact time greater than 0 will disable extrapolation and use the specified time interval.

Measuring the Temperature on a Large Part You may want to measure the temperature on a large part at more than one location. In this case, the temperature compensation is based on an average of those temperature readings.

To do this, you should measure multiple temperature points. When the TempComp command is executed, the sum of the readings is then reset in order to begin a new average for subsequent temperature readings. In addition, the average temperature is recorded. The sum of the readings is also reset when a probe is changed.

If you want to measure the temperature again, then you must execute the TempComp command to reset the recorded temperature before you measure it again. When calibrating a contact-based analog scanning probe, the measured tip size may differ from the nominal tip size, depending on the type of machine and type of calibration method selected. On some machine types this deviation may be calculated and sent to the machine controller as a radial deviation separately from the nominal size.

On these machines this deviation can be sensitive to how the calibration data was collected, particularly in terms of whether discrete hits or scans were used. This can sometimes lead to an apparent size discrepancy during post-calibration measurement, depending on whether a given feature is measured using discrete hits or scans.

Procedure Overview: To do this, scan a calibration artifact of known size. Typically you would scan one or more circles around the equator of a calibration sphere or the inside of a ring gage. Construct a circle feature from the scans, and then use a Calibrate Active Tip command to update the calibration data for the tip.

Do a traditional tip calibration. You can do this tip calibration by using a separate, already prepared, calibration part program, or in a preceding portion of the same part program used in step 2, or on the spot interactively by accessing the Probe Utilities dialog box and using the Measure buttons. See "Calibrating Probe Tips". Create a part program with the following: One or more scans that measure a calibration artifact of known size.

These are typically basic circle scans that measure the equator of a calibration sphere or the inside of a ring gage.

See "Performing a Circle Basic Scan". A best fit recompensated BF Recomp constructed circle feature that references the desired scans. Important: The theoretical size for the constructed feature must correctly match the size of the calibration artifact.

Also, you must specify the theoretical diameter for the measured artifact in the input parameters for the constructed circle. The difference between the theoretical and measured size of the constructed circle will be the basis for establishing the SCNRDV value. A "Calibrate Active Tip" command that references the constructed circle. When you use this command with this type of circle as the input feature, the calibrate single tip command does not require a reference to a calibration sphere.

Execute the part program describe in the previous step. Important: The BF recomp circle and "Calibrate Single Tip" commands described in step 2 must exist in the part program at the time the scans are executed for calibration, because they affect how the scans are executed on the machine.

In the above sample, a single circle scan inside a 50mm ring gage was performed, the constructed circle feature was created from that, and then the calibrate active tip command was used to update the SCNRDV value for the active tip. If appropriate for the particular measurement to be performed, the constructed circle may have more than one scan as input. For example, in some cases, a better average value might be obtained by including both a clockwise scan and a counterclockwise scan.

Renishaw SP25 Scanning Probes The procedure above is primarily oriented toward traditional analog scanning probes that are initially calibrated using discrete hits. Due to the probe being calibrated with discrete hits, subsequent measurements with discrete hits are generally good, but further adjustment is sometimes needed to get a SCNRDV that is more suitable for scan-based measurement.

For the Renishaw SP25 scanning probes the situation is somewhat reversed because the initial full calibration is performed using a series of scans.

The result of this calibration can sometimes be that scan measurement is good but a size discrepancy may then exist when measuring using discrete hits. To help address this issue, a modification has been made to the "Partial" calibration procedure for the SP That partial calibration uses discrete hits and updates the tip offset and size without changing the deflection coefficients produced by the full scan based calibration. Although the initial scan-based calibration for an SP25 may make it less likely to be needed; if necessary, this new SCNRDV procedure can be used with an SP25 just like with any other analog scanning probe.

It is assumed that a probe has been loaded and the tip you will use has been calibrated. Using a Probe On-line To measure a point in the on-line mode using a touch trigger probe: 1. Lower the probe to the surface where the point is to be taken.

Trigger the probe by touching it to the surface. Press the END key to complete the measurement process. Probe compensation is determined by the probe radius. The compensation direction is determined by the machine direction. For example, in measuring a circle, the probe would be inside the circle moving outward. To measure a stud, the probe would start outside the circle moving inward towards the part. AK-PC Controller pdf manual download.
