You can use a probe to check your part for correct dimensions during the machining process. For example, this program uses the work probe to check for squareness. The program uses G65 to call 9XXXXX macro programs created specifically for probing. You can find more information on these programs in the Renishaw manuals on the web at

The program does the following:

  1. After a tool change, home, and adding tool length compensation, the system turns on the work probe and moves to a safe start location.
  2. The probe stylus moves adjacent to the surface at the required Z-Axis point to provide a central start position [1].
  3. The cycle makes two measurements, symmetrically about the start position, to establish the surface angle [2], [3].
  4. Finally, the probe stylus moves to its safe out position, tuns off the probe, and returns home.
