一、用“截面样板”集与夹具构成“低精度部件构成系统”检测叶片叶片系一空间扭曲体,具有形状复杂参数多,精度高等特点(图1)。通常要在三坐标测量机或进口的表面轮廓仪上测量。我厂不具备上述仪器。我们采取如下方案:将引进机子上的叶片,卧顶于坐标镗床(昆明机床厂产),经测量,就得到该叶片的三坐标的“静态”数 First, the use of “cross-section model” sets and fixtures constitute a “low-precision component system” to detect a blade leaves a space distortion, with complex shape parameters, high precision (Figure 1). It is usually measured on a CMM or imported surface profilometer. I plant does not have the above equipment. We take the following program: The introduction of the leaves on the machine, lying on top of the coordinate boring machine (Kunming Machine Tool Plant production), measured to get the blade’s coordinates of the “static” number
