I need to program a 3 axis machining center to cut a
helical tool path. I use BobCAD to generate G-Code, but
the software will not generate code for this control.
Is this control (Fanuc 6M) capable of this function?
Do I need to turn on parameters for this function.
What is the G-code for XYZ plain?
Will someone Please give me an example or formula?
You may not have any Helical on your machine. If not, could bobcad generate a code that is a series of very short linear moves? Otherwise, maybe someone could suggest a formula for a macro that would include a DO/WHILE loop, to make very short G01 moves ( a few tenths at a time) to simulate a helical form...
yes you need to turn on options parameter on fanuc 6m to make it enable helical interpolation. and the program would be the same with using G3 or G2 for hellical with 3 axis moving at one time
I wrote a macro to do a helix but I dont have it here at home but this is how I do one on a control without macro programing (OMC)
1.75 inch hole 1 inch deep
G113(made a G code for it I use it so much)R.875(radius of hole)Z-1.0(end point absolute)Q.1(max depth of cut per rotation)S.01(start point this point is adjusted by the control so the the end point is ALWAYS corect)C.1(point it Z that it rapids out of the hole to) D21(geom+wear)
