I'm a recent convert to the power of sequential mill. For years I avoided it because I'd heard it was cumbersome, difficult to learn and headed for the dustbin. Sure, contour profile is relatively fast and easy but doesn't work so well when you want to start or end at particular spot (like corner picking).We recently recieved an NX file from a customer for one of their parts. It was programmed in NX4 and had hundreds of sequential mill operations. It was an education in just how much you can do with one toolpath. I also like how you can use almost anything, like a plane or a curve, to drive a tool.
