中凸变椭圆活塞外圆表面在位测量的研究

STUDY ON THE METHOD TO MEASURE PISTONS WITH MIDDLE BULGED VARYING ELLIPSE SHAPE ON MACHINE TOOL

提出了一种检测中凸变椭圆活塞外圆表面的新方法——在位测量，设计了在位测量的软、硬件系统，给出了系统非线性的反函数校正法，从而保证了检测精度，并对测量数据的处理进行了详细研究。生产应用表明在位测量系统能够满足活塞生产的要求。

A new method on measure of pistons with middle bulged varying ellipse shape is presented. The method is to measure pistons on the machine tool. The hardware system and software system for pistons' measure are designed. In order to rectify the nonlinear of the system, the inverse function method is introduced. It can assure the measure accuracy perfectly. A thorough study on how to deal with the collected datas is conducted. Its application in factories shows that the measure system can satisfy the requirements perfectly.
