A new technique for in-process measurement of surface roughness is introduced which employs an optical method by using double laser beams. This makes it possible to detect the surface roughness not only along the circumferential path but also along the feed direction even during machining. The experimental results show that the presence of chipping and chattering can be detected sensitively along both measurements directions and the maximum roughness value is always obtainable from the reading along the feed direction.
