摘要：
<正>An application for achieving on-machine truing/dressing and monitoring of diamond wheel is dealt with in dry grinding.A dry electrical discharge(ED)assisted truing and dressing method is adopted in preparation of diamond grinding wheels.Effective and precise troing/dressing of a diamond wheel is carried out on a CNC curve grinding machine by utilizing an ED assisted diamond dresser.The dressed wheel is monitored online by a CCD vision system.It detects the topography changes of a wheel surface.The wear condition is evaluated by analyzing the edge deviation of a wheel image.The benefits of the proposed methods are confirmed by the grinding experiments.The designed truing/dressing device has high material removal rate,low dresser wear,and hence guarantees a desired wheel surface.Real-time monitoring of the wheel profile facilitates determining the optimum dressing amount,dressing interval,and the compensation error.
