How do you use polar interpolation

[positiverake]

I was wondering if anybody can tell me how to mill on a live tool lathe with no Y axis, G112 polar interpolation, it looks like it ties the X and C togther ? is there a formula to figure this out,you know hex,square, raduis around the corners ect..

If you look at the program XC closer it is milling program, but instead XY coordinate now it is XC(where Y used to be now it is C), and X location is double.
That's it is.

What machine? What control? What cad cam software? Face? Cross milling?
If you use Mastercam I may be able to help.

Mori seiki Z1000 and dawoo puma, both have fanuc controls, no cad-cam, programing at the machine, just trying to understand how the G112 works, newtexas2006 post sounds good, have'nt tryed it yet, thanks for the reply

Just look at the "C" axis as if it were "Y". Program it as a 3 axis machine using X,C and Z do not try to think to much about how it works the G112 does all the thinking for you.
I have programmed Mori MC's fpr years and it is pretty far out how it works. Just remeber that oce the G112 is on you now have a 3 axis machining center and not a 2 axis lathe

Like they said, Dont think to hard, its easy after you get thru the brain strain..

Just remember to program C in Radius dimenision's and X in Diameter dimenision's....
you also have to turn cutter comp on and off outside the G12 thru G13 programming..

Its fun....
