涡旋体加工质量的检测

Measurement of Machining Quality of Scroll Wrap

基于涡旋体的三坐标仪检测数据,提出涡旋线型精度的两种检验项目,介绍了各自的数学处理过程。采用优化的方法来消除加工、检测两次定位造成的误差,确立了各自的目标函数。

On the basis of measured data from the scroll wrap by using three coordinate instrument, two check items of the scroll wrap are presented and their data processing methods are introduced respectively. By using numerical optimization algorithm, the machining errors and measuring errors caused by the positioning are e-liminated. Their objective function is defined respective- ly.
