Hello,
I am an experienced machinist and just want to know can you put in minus R values while using canned cycles for drilling.
So if you are drilling holes on the surface i.e. 'Z' zero you put in the following for example G81 Z-10 R2.(This is metric not inch figures).
This feeds down to Z depth of -10mm from Z zero starting at 2mm above surface.
Now if I had a pocket that was 40mm deep and needed several holes in the bottom face can you put a minus R value so it does not have to feed from the top Z zero surface.
Example G81 Z-43 R-38.
This rapids down to 2mm above surface of pocket base and then feeds from here to drill through base wall at 43mm depth.
I have worked with various verticle and horizontal CNC milling machines and they have this feature.
If this can't be done, I will carry on by programming each drilled position without a canned cycle for drilling.
Thanks
Mel
