Re: Machining Strategy ?

This topic is a little close to the edge, as it is not how to build a
machine, but it is still on the learning side....

We do try to keep away from speeds and feeds and such....

As for some pointers,

There is a place called the release point. a point (height) at which
the drill and other cutters will clear the top of the part and all the
clamps.

If every retraction you do is to or above the release point, then you
will save many headaches about snapping cutters that contact clamps.

I think the other really obvious thing is to not cut the perimiter of
a part and let it fall free, before doing ALL the bits inside !
