I think "rest machining" refers to doing initial machining passes with
a large-diameter cutter, having the CAM keep track of the remaining
material that needs to be removed, and then doing finishing passes
with a smaller-diameter cutter to remove that remaining material.
More generally it is using the stock remaining from the previous
operations as the input to the current operation.
My CAD/CAM (Synergy, Weber Systems) has a corner feature which allows
one to just finish off the corners. However, that is not a cure-all. I
can still manage to snap small end mills. I think the solution is to be
able to set a max spindle power which then adjusts feed rate as the
cutter loads up. Such a feature should help with chatter in corners as
well as broken end mills. The difficult part is making the power sensor
sensitive enough to preserve small end mills.
Continuing the sales pitch: it also has a roughing feature which allows
one to take multiples passes offset from the final path to remove
material. I don't use it very often as I find that the bandsaw or manual
programming is more efficient unless the extraneous material is well
balanced around the final shape.
There is a Windoze version which loses a few features but I run it on
Linux. :-)
