선삭가공시 LASER BEAM을 이용한 금속의 표면 거칠기 측정에 관한 연구

A Study on the Metallic Surface Roughness Measurement in Turning by Laser Beam

In - process measurement of surface roughness is introduced which employs an optical method by using laser beam. This makes it possible to detect the surface roughness not only along the circurnferential path but also along the feed direction even during machining. The maximum roughness value is always abtainable from the reading along the feed direction.
