Is this a Fanuc Control, if so which series?
Also i am assuming that you want to use a Hob End Mill, What Diameter??

WE MACHINE A LOT OF 316 SST,,,, WE USUALLY 2ND OP THESE IN THE VMC BUT I NEED TO HAVE THEM COME OFF THE MACHINE COMPLETE.

THANKS,

Do you have a Full Y Axis instead of using the C Axis??

If so, how much travel do you have?

[BAD DOG]

NO Y-AXIS THAT IS WHY I WANT TO TRY USING C AND LIVE Z AXIS TOOLING

BAD DOG

[tobyaxis]

Does your C-Axis Program in Degrees or an Inverted Scale??

[BAD DOG]

POLAR,,,,,,,

[tobyaxis]

I know this is an old thread but have you figured it out? I just had success programming a thread mill but using Cartesian to polar coordinate transformation on my fanuc control wouldn't work.use the y axis trust me. That way you can use the radius offset in your offset page which controls the y axis to control the dia like g41 cutter comp on a mill works.i can post an example if u want.im just replying to put the info out here in case you come across this again or it helps someone else.Best of luck
