1 问题的提出在汽车制造业中常常需要加工缸体、缸盖、变速箱壳体等箱体零件 ,这些箱体零件表面布满了空间孔系 ,为了满足汽车装配的互换性要求 ,必须保证这些相关孔系之间的位置尺寸关系。我们采用三坐标测量机进行测量 ,以保证这些空间孔系位置的加工精度。通过对缸体、缸盖
A problem raised In the automotive industry often need to process cylinder, cylinder head, gearbox and other parts of the box, these parts of the box filled with space hole system, in order to meet the interchangeability requirements of automobile assembly, must Ensure that these related holes between the size and location of relations. We use CMM measurements to ensure that the location of these spatial hole processing accuracy. Through the cylinder, cylinder head
