MC Nylon의 선삭가공에서 절삭조건과 노즈각도가 표면거칠기에 미치는 영향

Abstract

This paper investigates the effect of cutting conditions and nose angle on surface roughness when turning MC nylon. Taguchi technology in experimental design was used to reduce the number of experiments. Investigate the effect of five factors on surface roughness. Investigate the effects of cutting speed, feed rate, depth of cut, nose angle and nose radius. The results of variance analysis of the experimental results are as follows. Sensitivity affecting surface roughness when turning MC nylon was in the order of feed speed, nose angle, cutting speed, and depth of cut. Nose radius affects surface roughness. Under the same cutting conditions (cutting speed, feed rate, depth of cut, nose angle), 0.8mm nose radius showed better surface roughness value than 0.4mm nose radius. The feed rate shows very high sensitivity compared to other factors. Feed rate is the most important factor affecting surface roughness in MC nylon turning. The change in nose angle was found to be a significant condition for turning MC nylon. The smaller the nose angle, the better the surface roughness. Cutting speed and depth of cut are not critical for the formation of surface roughness in MC nylon turning.
