I am using a surface milling seq. with cutline option using Number cuts & offset increment parametes to control tool step depth and step over & scallop height to control tool step over. Pro/NC help says that when your are using offset increment parameter with scallop height specified, it will affect only the last slice but what i'm experiencing is that scallop height affects all slices not just the last one. I want it to affect only the last slice or else i'll have to define two surface milling sequences. Am i missing something?
