Chip Disposal System in Intermittently Decelerated Feed

Abstract

An attempt was made to break chip produced from NC lathing by intermittently decelerating the finish turning feed. A personal computer was used to make a part program involving the intermittently decelerated feed. As a result, it was found that the chip is broken into easily disposable smaller pieces by optimizing the interval and the rate of feed deceleration for a material cut. Also it was observed that the surface roughness is slightly improved.
