一、修理部位的确定 1.用高点的“动”与“不动”来判断应修理的部件这种方法可直观、快速、准确地确定修理部件和修研量。“高点”即量面上需要修研掉的部分,所谓高点“动”,即是高点随所用量块尺寸的不同,出现在固定测砧上的位置也在改变;高点“不动”,就是不论用哪一个尺寸的量块,高点所处的位置始终固定不变。表1是测量面平行度检定结果。当使用量块尺寸40.36检定时,影响测量平行度超差的这个“高点”为+5,处在活动测砧的位置4上,随着检定量块尺寸的不同(35.24,30.12,25),“高点”的位置也在改变,此时可确定修理部件为活动测杆工作面。如果随着检定所用量块
First, determine the repair site 1. With the high point of “move” and “do not move” to determine the parts to be repaired This method can be intuitive, fast and accurate to determine the repair parts and repair volume. The “high” is the part that needs to be repaired on the surface. The so-called high point “move” means that the position of the high point changes with the size of the measuring block. The high point “does not move ”That is, regardless of the size of the block used, the location of the high point has always been fixed. Table 1 is the measurement results of parallelism test. When using a gauge block size of 40.36, the “high” that affects the tolerance of the measured parallelism is +5 at position 4 of the active gauge, and as the dimensions of the gauge block are different (35.24, 30.12, 25) , “High” position is also changing, this time to determine the repair parts for the active rod face. If with the verification of the amount of block
