Hi Tim

EMC does support lathe and threading, with one proviso. Tapered threads
are not specified as per any standard out there. They measure the pitch
along the taper (hypotenuse) rather than along the screw axis as per all
the threading standards.

Means custom threading formulae in post processors to get the correct
pitch.

Canned cycle G76 does not support tapered threads at all.
