I would like to know some specifics on that set up. Workpiece material, cutting tool material, etc.
Saw similar thing back in the early 70's, but not glowing, in the Systems Engineering department in college. After the cut, the chips dak purple, radiating heat you could feel from 10 feet away. The workpiece was cool to touch. Was a big lathe fitted with a MONSTER motor. They were developing and testing ceramic tooling.

When I first got my lathe I talked with my dad a good deal. He was in the plastic injection molding business his entire career. Both as a mold designer, product designer, and building molds in tool rooms. He told of a time that his boss set him up to hard turn. All of his learning in relation to tool and die work was "on the job training", some self taught. The hard turning was not going well so he asked his boss for advice. Boss asked if the lathe could turn faster, so my dad upped the speed of the spindle. This happened 2 or 3 times. By the time the work was coming out as desired the swarf was burning like the sparks off a cut-off wheel, he said the only bad part was the cleanup after the job.
