ZEISS MCR20 Automatic Probe Changing Frame
Product Information
The product is a Coordinate Measuring Machine (CMM) with an automatic probe changing feature. It is used for precision measurements and inspections. The CMM is compatible with different probe holders and sensors, including the XXT sensor on the RDS articulating carrier.
Troubleshooting errors with automatic probe changing
By Aaron Wilt, Technical Support Specialist
Problem: CMM fails to drop off or pick up a probe from the holder rack during automatic probe changes in Calypso. The machine may travel to the correct area but doesn’t quite line up with the holder properly
Troubleshooting steps:
First, we need to check the alignment of the probe holder rack. The rack
should be aligned within 0.1mm from end to end, parallel to a given axis
(depends on CMM type and size). Use the CMM to probe two points on a surface
parallel to the aligned axis (X in the example below), but on opposite ends of
the rack. If necessary, loosen the bolts securing the rack to the table and
adjust the placement until the coordinates are within 0.1mm of each other.
Once finished adjusting, re-tighten the bolts to secure the rack and
doublecheck the alignment once fixed
INSTALLATION INSTRUCTIONS
Second step is to redefine the holder locations through Calypso using the master probe. Place the master probe plate onto the sensor and perform the manual pick up command. If applicable, articulate the carrier to the angular position necessary to interact with the probe holder rack (RDS articulating carrier with XXT sensor)*. Open the automatic stylus change window.
Now click the Define Stylus Length button in the upper right corner of the window
Now follow the onscreen prompt to probe on the stylus plate like so
Next probe the same surface with the stylus tip
You will see a dialog window showing the stylus length calculated.
Now left click on the graphic to select the probe holder you want to locate. Right-click and select Define Holder Location
Follow the prompt and position the stylus above the holder’s locating feature. For the XXT probe holder this feature is a half-sphere-shaped indentation on the left most holder in the grouping of 3.
When you click OK the machine will lower itself down and find the feature. The color of the holder graphic will change to show that the holder location has been defined
Execute the above steps for each holder you have on your rack. Then test the automatic probe change.
