GB/T 16857.5-2017 in English

《GB/T 16857.5-2017产品几何技术规范（GPS） 坐标测量机的验收检测和复检检测 第5部分：使用单探针或多探针接触式探测系统的坐标测量机》由TC240（全国产品几何技术规范标准化技术委员会）归口，主管部门为国家标准化管理委员会。

Scope

This part of GB/T 16857 specifies the methods for acceptance testing and re-inspection testing of the characteristics of a coordinate measuring machine with a tactile probing system, and is only applicable when the coordinate measuring machine has the following configurations - any type of tactile probing system; --- mode of discrete point detection; --- the probe needle is spherical or hemispherical. This part of GB/T 16857 applies to coordinate measuring machines with any of the following configurations, a) "single-probe probing system b) "multi-probe probing system, that is, multiple probes are fixedly connected under one probe (such as Star probe) @) multi-probe detection system, if multiple probes are configured, each probe is equipped with a probe d) universal detection system; e) probe and probe exchange system; although, manual (Driveless) Coordinate Measuring Machine. This section does not apply to non-ship-mounted detection systems, which require a different detection step. For the convenience of users, "dimensional error of the multi-probe probing system of a coordinate measuring machine" is simply referred to as "multi-probe dimensional error". If it is possible to separate the characteristics of the probing system from the characteristics of the coordinate measuring machine, then the The impact can be ignored.See Appendix C for details.
