1 Scope

GB/T 16857.901-2020 is the Chinese national standard on geometrical product specifications (gps) - acceptance and reverification tests for coordinate measuring machines (cmm) - part 901: cmms with multiple imaging probing system, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 March 2020 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2020. Classification: ICS 17.040.30, CCS J04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

5.3 Environmental conditions The allowable extreme values of environmental conditions, including the temperature, humidity and vibration of the coordinate measuring machine installation site that affect the measurement work, are specified as follows:

---Acceptance testing, specified by the manufacturer;

---Re-inspection and testing shall be specified by the user. In both cases, the user can arbitrarily choose the environmental conditions within the allowable extreme value range. In the acceptance test, the user has the responsibility to provide the coordinate measuring machine with the environment specified in the manufacturer's technical indicators. If the environment is not in compliance Fan, can not be required to verify the maximum allowable error or maximum allowable difference in this section.

5.4 Operating conditions For the inspections specified in Chapter 6, the CMM should be operated in accordance with the procedures given in the manufacturer's operating manual, and the instructions in the operating manual should be followed. Specifications, including.

---Machine start/warm up;

--- All detection systems tested should meet their rated working conditions;

---Cleaning procedures for detection system and standard equipment;

---Calibration of the detection system;

--- If specified by the manufacturer, the standard device should be installed in the location specified in the operation manual. Before calibration of the detection system, all key components of the detection system, such as lenses, mirrors, standards, etc., should be cleaned to remove possible effects. Residues from measurement or test results. During the calibration and detection of the detection system, it should be ensured that the detection system basically reaches thermal equilibrium.

6 Acceptance test and re-inspection test

6.1 Overview The acceptance test shall be carried out in accordance with the specifications and procedures specified by the manufacturer, which shall comply with the relevant requirements of this part; re-inspection and testing It should be implemented in accordance with the specifications specified by the user and the procedures specified by the manufacturer.

6.2 Principle The detection method in this chapter is used to detect the maximum allowable error of the multi-image detection system. Each detection system shall be specified by the equipment manufacturer The operation of all detection systems should comply with the normal operating procedures of the coordinate measuring machine manufacturer. The principle of the detection method is.

a) Use the calibrated detection circle to determine that the measurement characteristics of the coordinate measuring machine equipped with the parallel multi-image detection system meet the specified shape Maximum allowable error of shape PForm.Cir.n×25.PMIPS, maximum allowable error of size PSize.Cir.n×25.PMIPS, maximum allowable error of position Poor LDia.Cir.n×25.PMIPS;

b) Use the calibrated detection ball to determine that the measurement characteristics of the coordinate measuring machine equipped with a non-parallel multi-image detection system meet the specified requirements Maximum allowable error of shape PForm.Sph.n×25.NPMIPS, maximum allowable error of size PSize.Sph.n×25.NPMIPS, maximum allowable error of position Poor LDia.Sph.n×25.NPMIPS. For a multi-detection axis coordinate measuring machine, if the measurement space of each detection axis is highly overlapped, the detection process is the same as the configuration on a single detection axis The detection process of the coordinate measuring machine of multiple detection systems is the same. If the measurement space overlap is small, the detection of each detection axis should be tested separately. For multi-detection axis coordinate measuring machine, it is recommended to detect the error of one detection system on each detection axis with reference to GB/T 16857.7 at least. difference. If the measurement space of each detection axis overlaps greatly, it can be negotiated. Refer to GB/T 16857.7 to detect the error of only one detection system. But the number of detection positions should be increased.
