To solve the problem that truing and dressing of superabrasive grinding wheels are very hard, a method which is called "laser and mechanical compound truing and dressing" is used. Multiple-pulse finite element simulation is done to optimize laser parameters during laser rough trimming and reach a certain circular runout range of grinding wheels after laser rough trimming. Through simulation results, laser parameters of laser rough trimming are selected. Then, laser and mechanical compound truing and dressing experiments are done for bronze-bonded diamond grinding wheel which is just die-casting molding. Results show that if appropriate technological parameters are selected, laser and mechanical compound truing and dressing is an effective method.
