误差补偿技术在直廓环面蜗杆高精度加工中的应用

针对如何在普通滚齿机上低成本地提高直廓环面蜗杆加工精度的问题，通过采用三坐标测量机对实际齿面进步坐标测量，由所得的测量结果与理论的蜗杆齿面进行比较分析，找出机床加工参数的调整误差，根据所得机床调整参数误差并基于误差补偿原理修正机床调整参数，从而明显地提高了直廓环面蜗杆的加工精度，同时，在保证有充足测点的条件下，只需沿着工件表面的一条螺旋线进行测量，使可较为准确地诊断出机床加工参数的调整误差，从而提高了蜗杆的检测效率。

Application of Error Compensation Methods in High Precision Machining of Globoid Worm

To the question how to improve the machining precision of globoid worm at an easy rate,a method that uses cooridinate measurements of real tooth surface of globoid worm is proposed. It can determine the real applied machine tool settings. The deviation of the real tooth surface from the theoretical one,can be indentified by the method. The deviation can be minimized by correction of the machine tool settings,the machining precision of globoid worm be improved by the same machine. Validity of the method is verified by succeeding manufacturing experiment. On the other side,only one helix is needed to be measured,then the error of machine tool settings can be identified under the condition of adequate measured points,so the measured efficiency of worm is improved.
