Webinar: Chip Breaking Using NC Programming

In turning operations, the formation of long stringy chips has been a persistent problem. These chips can tangle around the tool or work-piece, forming a “bird’s nest,” and they often require manual removal. Strategies that have been used in the past in an attempt to solve the problem include chip-breaking geometries on the tool and high-pressure coolant directed at the cutting zone.

During this webinar, Dr. Scott Smith of Oak Ridge National Laboratory will show a new strategy that always breaks chips during this webinar. It is material independent, and requires no new equipment. Rather, a modification to the NC program ensures that the chip will always break. It is even possible to program the desired chip length. The strategy works for any common lathe operation and tool path including turning, taper turning, contour turning, boring, and facing.
