面齿轮磨削齿面齿形误差修正

以面齿轮齿面的形状误差为研究对象,建立了面齿轮齿面数学方程,通过三坐标测量仪（CMM）对面齿轮齿面进行了误差测量。为提高面齿轮齿面的精度,提高其理论和工程的应用价值,提出了一种基于序列二次规划（SQP）的面齿轮齿面误差评定方法。建立了齿面误差的识别方程,应用序列二次规划算法对机床加工参数进行优化求解,并与最小二乘优化法进行对比,应用修正后的机床调整参数,再次通过三坐标测量仪对修正后的齿面误差进行检测,验证了该方法的可行性。

Tooth Surface Form Error Correction for Face Gear Grinding

The form errors of the face gear tooth surfaces were taken as the research object, the mathematical model of face gear tooth surfaces was established,and the error measurements of face gear tooth surfaces were conducted by CMM. In order to improve the accuracy of face gear tooth surfaces and enhance the application values of theory and engineering, an error assessment method of face gear tooth surfaces was proposed based on SQP. With the identification equation of the tooth surface errors was established, the processing parameters of the machine tools were optimized by using SQP algorithm. And compared with the least squares optimization method, the modified machine tool adjustment parameters were applied, the modified tooth surface errors were detected by CMM again, which verified the feasibility of the method.
