I once used a device that added a hydraulic knee to a bridgeport. A probe
mounted on an arm actuated it. When moving the table in X and Y, the probe
caused the knee to raise and lower so as to keep the probe in contact with
the surface of the object. This, in turn, caused the cutter to cut the stock
to the proper depth.
That was around forty years ago.
If you mounted an electrical probe parallel to the head in that way, you
could do the same thing with EMC. The state of the probing command in EMC2
is uncertain, though.

Subject: [Emc-users] Is there an easy way to work with an irregular
surface?
I would like to automate the cutting of objects found in nature that are
roughly spherical and vary in radius. What seems to make sense is to issue a
G code command to make the cutting head move until a limit switch is
triggered on the surface of the object; disable the limit switch; use
relative motion commands; repeat. Has anyone encountered anything like
this? Is there a way to do what I'm attempting without scanning the entire
object first?
Thanks - Mike
