A Study on the In-process Measurement of Metallic Surface Roughness in Cylindrical Grinding by Laser Beam
원통연삭가공시 레이저 빔을 이용한 금속 표면거칠기의 인프로세스 측정에 환한 연구
Abstract
This paper deal with the design of noncontact In-process measurement system which measures the surface roughness during cylindrical grinding. The measuring system is extremely simple and the apparatus proposed is composed of a laser unit, photodetector and optical system. The experimental performance of the apparatus is satisfactory and good results are expected in the actual use. During operation, the surface of a workpiece Is continuously scanned by a laser beam. The experimental results show that the presence of chattering, loading and glazing can be detected sensitively along both circumferential and feed directions and the surface roughness value is obtained from the reading along the feed direction.
