Circular interpolation and Mastercam 2018

[Patrick72190]

Hi,

I am new to this site and also to Mastercam. I have written a few turning programs using it. The problem I am having is the programs that have been generated use incremental programming with circular interpolation "I" and "K'. I prefer to use absolute "R". Could somebody please tell me how to get Mastercam to generate programs using an "R". Any help would be very much appreciated!Thank you!
