以坐标测量方法评价矩形花键位置度的快速判定

摘要

探讨了用三坐标测量机准确测量矩形花键位置度公差的原理和基本方法。从花键的联结配合介绍了评价矩形花键位置度的重要性和传统的评价测量方法，以实际生产中齿轮矩形花键为例阐明了三坐标测量键槽位置度的数学原理并提出一种新的数据处理方法来评价工件。%This paper mainly discusses about the principles and basic methods of using CMM to accurately measure the tolerance of rectan-gular spline position. The paper starts with the introduction about the value and the traditional assessment and measuring methodology of rectangu-lar spline position while emphasizing on its connection and Coordination. Then the paper illustrates the mathematical principles of rectangular spline position use by CMM while taking the rectangular spline as an example and in the end concludes with a new data processing method, with which we can assess the workpiece more effectively.
