摘　　要：利用杯形砂轮修整器对圆弧砂轮进行修整,并采用非接触式位移传感器实现对圆弧砂轮的测量,提出将修整后圆弧砂轮的圆跳动误差值与圆弧半径误差值网格化后用于评价修整效果。根据磨削加工原理,计算匹配的修整测量参数并利用修整误差进行补偿加工。修整实验表明,杯形砂轮修整方式是一种理想的修整方式,对比传统的磨削加工,修整误差的补偿加工效果明显,两次补偿加工后的面形误差分别减小了36.5%和28.1%。The cup-wheel is adopted in arc grinding wheel truing and the non-contact displacement sensor is used for arc grinding wheel measurement.The radial run-out error and arc radius error after meshed are proposed to evaluate the quality of the truing.The matching truing measurement parameters are calculated based on the principle of aspheric grinding,by which truing error compensation grinding is carried out.The results of truing experiment show that the cup-wheel truing is an ideal truing method.Compared to tradition grinding,the effect of truing error compensation is obvious.The surface form errors after two compensation grinding decrease by 36.5% and 28.1%,respectively,which means the truing error compensation grinding can effectively improve accuracy.
