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。
In order to solve the hard dressing problem of super-abrasive abrasive wheel, laser-mechanical composite dressing method is adopted to simulate the removal process of bronze cement by multi-pulse finite element method, to optimize the laser parameters of laser roughing process and to determine the grinding wheel Round beating can reach. According to the simulation results, the parameters of the laser roughing laser were selected under the condition of trimming experiment. The laser-mechanical composite trimming experiment was carried out on the sintered bronze diamond grinding wheel. The results show that the laser - mechanical compounding method is an effective dressing method under the suitable process parameters.
