it gave an erors Zero radius arc line12, but looks promising then finished I will send it to Posprocessors Forum.
Many thanks to every one again.
K is an arc modifier in Z axis similar to I&J for x/Y along with other things in different cycles. Look it up in the manual page 10-9 I believe.
If you were at v2.02 then then the problem I mentioned would not be causing your problem .
I think you need to find a proper postprocessor for your cam program to drive mach correctly. Being complex is not a problem with MACH. It just needs the proper command language to do it correctly.
