Calculating "zero" with Radius tool...
Hi all,
I just wanted to double check on something, before I do something stupid, and crash...
So, using end mills (Mastercam X2), (flat, bull etc) I know that the "zero" Z-Axis point usually is the top of the part (if I am off course cutting in the Negative z-direction).
Using Mach3, I have a touch probe, and I can very accurately do that, never had an issue. Depth cuts are spot on.
My question is now I want to use some "profiling" bits (like for example, a .25 Radius bit) to create a radius around a part, AFTER I cut it say with an end mill.
Since I need to change the mill, what is the "zero" point for a profile bit? How does one calculate this, to make sure that the machine cuts at the proper depth, and not ruin the part?
Do I lower the radius bit to the point where I want it to start cutting, and tell the machine that is the Zero point?
I am sure I am missing something simple, but wanted to check with the experts here, before doing something stupid....
Thanks all in advance for any insight!
