针对成形法精密磨削加工螺杆转子螺旋面的问题,研究了螺杆转子加工过程中由工艺系统误差产生的齿廓加工误差的补偿方法。提出了一种基于首件转子磨削后的齿廓测量误差,进行预处理再修整砂轮的新算法。使用处理后的补偿数据对砂轮修整后,加工误差明显减小与收敛,大大提高了磨削转子的齿廓制造精度。 Aiming at the problem of precision ground grinding screw rotor surface by forming method, the compensation method of tooth profile machining error caused by process system error during screw rotor processing was studied. A new algorithm based on the error of profile measurement after grinding the first rotor was proposed. After using the processed compensation data to dressing the grinding wheel, the processing error is obviously reduced and converged, which greatly improves the manufacturing precision of the grinding tooth profile.
