General Mach Discussion / Oscillating bit in Z axis to equalize tool wear
« on: September 19, 2011, 01:25:41 PM »
Hello,
I have a grinding application in which I use a cylindrical diamond coated bit to cut 2D parts from sheet stock that must be ground, not milled. The sheet is a laminate and one layer of it is very hard on the diamond, stripping it quite rapidly. I can cut more parts before a tool change is required if I oscillate the bit up and down. At present I do this by post-processing my g-code to add the additional movement, however this carries several disadvantages for me. It would be convenient to simply turn on a function from within my g-code that causes Z to oscillate up and down about its current position at a specified frequency and amplitude. Can anyone suggest a means of doing this?
Thanks.
