Hi
Could anyone give me an example code for helical milling on this machine,

I need to mill a 13mm diameter hole radially through the wall of a part, OD is 40mm, ID is 35mm, hole centre is 15mm in from face in Z

Using a 10mm end mill

Doosan Fanuc i control

I could drill but I have several different size holes to do, and learning this code would be very helpful.

Thanks

I think this should do it (I'm in a motel room, and can't test it). Not sure about the L repeat command, though. If that doesn't work, just repeat the G03 block 10 times or put it into a subprogram.

Whats the "P12" and "K6.5"?

[dcoupar]

M03 P12 starts the live tool spindle.
K6.5 is the Z-axis arc-center distance.

Used this code on friday on a new job, it worked fine. Many thanks dcoupar for your help.
