要提高制件的加工精度和进一步提高劳动生产率.不广泛地采用自动量仪是不可能的.但是对于间断面制件来讲.由于工艺上的一系列困难.自动测量目前还只能在一定条件下使用. 间断表面制件的自动测量方法中.采用通过制件的空缺时锁住测量系统的可动部分的办法最为普遍.这种方法能防止测头落人制件的空缺部份内以及避免测量时发出错误控制信号.在这种仪器中.测量系统 To improve the machining accuracy of parts and further improve the productivity of labor.It is not impossible to use automatic measuring instrument not widely.But for the parting parts, due to a series of difficulties in the process, automatic measurement can only be done at present Use of automatic discontinuities in the surface of the measurement method, the use of parts through the vacancy lock the movable part of the measurement system is the most common method to prevent the loss of the probe part of the missing parts As well as to avoid false control signals when measuring. In this instrument. Measuring system
