I doubt that you will me machining camshafts at 20,000 rpm. (Especially not if the cutter needs to dive in and out) For grinding you need to consider how the contact point rolls above and below the centre line. I did do the maths, when I did the crank-grinding mock-up. But only for a circular but eccentric result. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
