在平板测量中,为保证所检验零件的侧量精度,显然必须首先保证平板本身的精度。因而在推广平板测量的过程中,就有必要使检验人员和计量人员普遍掌握检定平板精度的方法。由于平板本身就是作为基准使用的,因而往往不可能再找到一个比平板精度更高、尺寸更大的实际平面,来作为检定平板时的客观基准,而只能通过测量方法本身来体现一个既看不见,也摸不着的理想平面,以作为测量基准,这样就决定了检定方法难免比较复杂。
In the flat-panel measurement, in order to ensure the accuracy of the side of the inspection parts, it is clear that must first ensure the accuracy of the flat itself. Therefore, in the promotion of flat-panel measurement process, it is necessary to make inspectors and measurement staff generally grasp the test plate accuracy. Since the tablet itself is used as a reference, it is often impossible to find an actual plane of higher precision and larger size than the tablet as an objective reference when testing the tablet, but only by the measurement method itself Not seen, but also the ideal plane of the touch, as a measurement basis, thus determining the test method is inevitably more complicated.
