An engine is composed of many components of various shapes, and the manufacturing quality of these components is directly related to the performance and life of the engine. Therefore, it is necessary to use a CMM for very precise testing in the production of these components to ensure the accuracy and tolerance fit of the product. In the modern manufacturing industry, high-precision integrated CMMs are increasingly used in the production process, gradually transforming the goal and key of product quality from inspection to controlling the manufacturing process, and timely adjusting the parameters of processing equipment through information feedback, thereby ensuring product quality and stabilizing the production process, and improving production efficiency.

In the selection of traditional measurement methods, people mainly rely on two measurement methods to complete the measurement of box type workpiece and complex geometric shape workpiece, that is, using a coordinate measuring machine to perform the detection of box type workpiece; The measurement of workpieces with complex geometric shapes is completed through special measuring equipment, such as special gear detectors, special cam detection equipment, etc. Therefore, for enterprises engaged in the production of complex geometric workpiece, quality control enterprises that complete the above products not only need to configure general measuring equipment, such as coordinate measuring machines, general standard measuring tools, gauges, but also need to configure special testing equipment, such as various size types of gear special testing instruments, cam testing instruments, and so on. This often leads to the need for the measurement department of an enterprise to allocate multiple types of measurement equipment and professional testing personnel engaged in measurement operations, resulting in a low utilization rate of measurement equipment, while the enterprise bears a higher cost of training measurement personnel and the use and maintenance of measurement equipment; Enterprises cannot achieve flexible and universal metrological testing. Therefore, reducing the measurement costs of enterprises, the training costs of measurement personnel, and the use and maintenance costs of measurement equipment to achieve the goal of improving the efficiency of measurement and testing, and enabling enterprises to have real-time quality control capabilities in the production process, will affect the resilience of enterprises in market activities, and have an important decisive role in helping enterprises establish and maintain good market reputation.
