Research Progress of On-line measurement and Compensation Technology about Grinding Wheel Wear

摘要

According to the characteristics of grinding wheel wear in the grinding process, the grinding wheel wear forms and their reasons are analyzed. At the same time, as the grinding wheel wear will affect the size of components, the procedures of on-line measurement and compensation technology about grinding wheel wear are summarized. The current domestic and international research status of on-line measurement and compensation methods about grinding wheel wear are introduced, such as position calibration based method, machine vision based method, laser displacement based method, acoustic emission based method, grinding force based method, cutting vibration based method, grinding acceleration based method and pressure based method. Finally, the current research difficulties of grinding wheel wear's on-line measurement and compensation technology are analyzed, and the further research direction is made.
