精确地测量内孔R槽轴向尺寸,一般来说是较困难的。我厂在加工如图1所示的工件时,就碰到这个问题。由于R槽之间及与端面之间的轴向尺寸要求较高,故采用样板或成形量具测量不能保证工件的精度要求。
Accurately measuring the axial dimension of the inner groove R slot is generally more difficult. I plant in the processing of the workpiece shown in Figure 1, it encountered this problem. Due to the high requirement of the axial dimension between the R grooves and the end face, the accuracy of the workpieces can not be guaranteed by using the sample or forming measuring tools.
