Re: EMC, ISA and other Questions... - 4th axis angular feedrates

A very fixable problem indeed,
I made available the algorithms I'd developed on 4th axis angular
feedrates over 6-months ago to anyone who wanted it, although I think
it was just Art who's really developed on from there and solved this
problem for Mach1. If anyone want's a copy then drop me an email or
better yet, ask Art who's made a far better job of it, although I'm
still using the same old algorithms for 5-axis machining.
You could also do the calculations as a seperate post-processor
operation if neither your CAM package nor controller package will do
this. In fact, I think Dan Statman has also independently done this
just by using an Excel spreadsheet !
