摘要
为了解决超硬磨料砂轮修整困难的难题,采用激光-机械复合修整法,通过对青铜结合剂的去除过程进行多脉冲有限元仿真,优化激光粗修工艺的激光参数及确定激光粗修工艺过程砂轮圆跳动所能达到的范围。根据仿真结果选择了修整实验条件下激光粗修的激光参数,并对烧结成型的青铜金刚石砂轮进行了激光-机械复合修整实验。结果表明在合适的工艺参数下,激光-机械复合修整法是一种有效的修整方法。
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 fiaite element simulation is done to optimize laser parameters during laser rough trimming and reach a certain circular ranout 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.
