CMM inspection is a precision measurement technique used to measure the three-dimensional coordinate position and shape of an object.    It is usually performed using a CMM or an optical measuring system. CMM can accurately measure the length, width, height, angle and other parameters of an object, and is widely used in the manufacturing industry for quality control, process optimization and product development.    Through CMM, precision measurement and analysis of products can be realized to ensure that the products meet the design requirements and improve production efficiency and product quality. The development of CMM technology also promotes the digital transformation and intelligent production of manufacturing industry.

In terms of system management, our company strictly in accordance with the requirements of the IATF16949 quality management system, such as the annual calibration of equipment through the manufacturer, as shown in Figure 2, 3 this is our 2023 calibration of the certificate of conformity, internal control, we will be daily inspection of the equipment, to ensure that the equipment can be operated normally, as shown in Figure 3 for the internal daily point inspection table;

Fig. 4 shows that the inspectors are testing the dimensions of the product through the CMM, which is a stainless steel part used in the EGR cooler of the automobile exhaust gas treatment system, the name of the product is the outlet chamber, the overall dimensions of 58mmx34mmx115mm, the weight of 452g, the product's main production process is to produce a blank through precision casting, and then made into parts that meet the requirements of the drawing by machining, and then the sealing test.

The main production process of the product is to first produce the blank through precision casting, and then through machining to make the parts that meet the requirements of the drawings, and then carry out the sealing test and appearance test, and finally the qualified products are packed and put into the warehouse;       shown in the figure is the debugging parts of the first time after we start the machine, and the technicians will determine the next step according to the test data provided by the inspectors, such as the detection of unqualified, will be adjusted to the target until the debugging of the qualified, and then proceed to the bulk processing.
