Hwacheon Lathe Fanuc 0i-TD


Milling this profile on my C axis:





sorted the finished profile but can't take it in a single cut so need some ruffing cuts.
Could work out each ruf profiles but could I simply adjust the tool offset or tool R on the fly to offset the finish geometry for multiple ruffing passes?
Can I adjust the appropriate param for each call of the profile as a sub?
These are the only params I can find? any suggestions? Cheers, Sean
