---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;

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.
6.3 Parallel multi-image detection system
6.3.1 Measuring equipment
The detection circle is used as the physical standard, and its nominal diameter should be no less than 10mm and no more than 51mm. If the image detection system
In the same field of view measurement mode, the diameter of the detection circle should be 10% to 66% of the diagonal of the field of view of the detection system.
The size and shape of the detection circle should be calibrated. Since the shape and size deviation will affect the test results,
When complying with relevant specifications, GB/T 18779.1 should be used to consider the influence of the size and shape of the detection circle. It is recommended that the shape error of the detection circle should not exceed
Passed PForm.Cir.n×25..PMIPS, 20% of MPE.
6.3.2 Procedure
Place the standard in 3 different positions for testing. One of the positions is close to the calibration position, and the other two positions are off the calibration
Set as far as possible, but the distance does not exceed 50% of the CMM stroke. The user can choose the position of the standard arbitrarily within the allowable range.
For each of the n parallel image detection systems, the detection circle is measured at each of the 3 detection positions. 25 for each circle
Points, these points should be approximately evenly distributed within the angle range (see ISO 10360-7.2011).
6.3.3 Test data analysis
Analyze the detection data of 3 positions separately.
At each position, for all n×25 points obtained by n parallel image detection systems, the unconstrained least square method is used to fit the circle, and then
To 1 fitted circle. Calculate the distance from all n×25 measurement points to the center of the fitted circle, and the range (Rmax-Rmin) of all distances is the test
The shape error of the measured position PForm.Cir.n×25.PMIPS. The absolute value of the difference between the diameter of the fitting circle and the calibration value of the detection circle diameter is the detection
The size error of the position is PSize.Cir.n×25.PMIPS.
At each position, 25 measurement points of n parallel image detection systems are respectively fitted to the circle by the unconstrained least square method, and a total of
n fitting circles, the smallest circumscribed circle diameter including the centers of all fitting circles is the position error LDia.Cir.n×25.PMIPS of the detection position.
6.4 Non-parallel multi-image detection system
6.4.1 Measuring equipment
The detection ball is used as the physical standard, and its nominal diameter should be no less than 10mm and no more than 51mm. If the image detection system
In the same field of view measurement mode, the diameter of the detection ball should be 10% to 66% of the diagonal of the field of view of the detection system.
The size and shape of the detection ball should be calibrated. Since the shape and size deviation will affect the test results,
When complying with relevant specifications, GB/T 18779.1 should be used to consider the influence of the size and shape of the detection circle...
