ABSTRACT
This chapter reviews very recent and on-going interests and developments being reported from the world-over in the area of Diamond turn machine (DTM). Almost all aspects of DTM have drawn the interest of researchers: machine tool structure, cutting tool, work material, process monitoring, tool holder, path planning, effect of coolant and so on. A sensor fusion approach has been proposed for monitoring the DTM process. The DTM group in Hong Kong Polytechnic has reported attempts in developing techniques to monitor surface roughness during the DTM cutting process. Interesting studies on coolant enhancements have been attempted in the DTM process. Light scattering tests are performed to show that application of random vibrations suppress the scattering fringes normally seen on DTM machined surfaces. Vibrations to cause tool-chip intermittent contact losses are largely based 'elliptical vibration cutting' where, the tool makes an elliptical cutting motion at high frequencies.
