I have put together some training notes relating to the probe builder and custom disc probes with selectable roller tips that I though the community could benefit from.
This came about from repeated questions relating to "What are the little bumps on the discs?" that regularly came up when I was training customers.
These custom disc probes will allow you to easily measure groove widths with the rollers as they are selectable calibrated tips (without having to resort to math calculations).
The link below contains the following:
- PDF document that provides a brief overview of the Probe Builder with an example of a custom disc probe with selectable roller tips.
- PDF document outlining the calibration methodology for custom disc probes with selectable roller tips.
- usrprobe.dat file that contains the custom probe data for all Renishaw and Hexagon Disc Probes that have rollers (non-roller discs are already in the PC-DMIS probe.dat file)
- An excel file that calculates the required calibration angles and approximate clearances for either a user input values or a pull down list for the disc probes from the supplied usrprobe.dat
- Numerous .draw files for the imported CAD geometry for the various roller sizes
- Readme file outlining which PC-DMIS folders the relevant files need to be copied to, you will need to relaunch PC-DMIS after copying the files.
- An example probe file for a 25mm disc with roller tips.
The information has been gathered from various Hexagon PC-DMIS help files (PDFs contain hyperlinks to the sources) as well as my own problem solving to determine a method to calibrate the rollers.
Please review and provide any feedback in this thread.
If you find anything is incorrect or needs updating, please feel free to let me know.
P.S. PDFs also attached incase in the future the link breaks for some reason
