The relation of Cutting conditions and Microscopic precision
고속가공시 절삭조건과 미시적 정밀도의 관계
Abstract
This paper deals with the relation of cutting conditions and damaged layer by investigating cutting force, cutting temperature and residual stress in high speed machining. Damaged layer was measured using optical microscope on samples prepared by metallographic techniques. The scale of this damaged layer depends upon characteristics of cutting force and cutting temperature. Damaged layer depth increases with feed per tooth and radial depth. In a different another way, damaged layer remains almost unchanged according to spindle speed. Therefore, the effective method for decreasing damaged layer is that cut down feed per tooth and radial depth.
