The coordinate measuring machine is a measuring system that detects the three-dimensional coordinates of the surface points of the workpiece through the relative movement of the probe system and the workpiece. By placing the measured object in the measurement space of the CMM, the coordinate position of each measuring point on the measured object is obtained by using a contact or non-contact detection system. According to the spatial coordinate values of these points, the software performs mathematical operations to obtain Geometric size and shape, location to be measured. Therefore, the coordinate measuring machine has the characteristics of high precision, high efficiency and versatility, and is an ideal solution to complete the geometric measurement and quality control of various auto parts.
Auto parts have the characteristics of high quality requirements, large batches and different shapes. According to different measurement types of parts, it is mainly divided into three types: box, complex shape and curved surface. The configuration of each type of relative measurement system is not the same, and it is necessary to carry out interaction from the mainframe of the measurement system, the detection system and the software. matching and options.
In modern manufacturing, high-precision comprehensive measuring machines are more and more used in the production process, so that the goal and key of product quality are gradually transformed from final inspection to control of the manufacturing process, and the parameters of processing equipment are adjusted through information feedback. Make timely adjustments to ensure product quality and stabilize the production process to improve production efficiency.
The engine is composed of many parts of various shapes, and the manufacturing quality of these parts is directly related to the performance and life of the engine. Therefore, very precise inspections are required in the production of these parts to ensure the accuracy and tolerance of the products. In modern manufacturing, high-precision comprehensive measuring machines are more and more used in the production process, so that the goal and key of product quality are gradually transformed from final inspection to control of the manufacturing process, and the parameters of processing equipment are adjusted through information feedback. Make timely adjustments to ensure product quality and stabilize the production process to improve production efficiency.
In the selection of traditional measurement methods, people mainly rely on two measurement methods to complete the measurement of box-type workpieces and workpieces with complex geometric shapes, namely: the detection of box-type workpieces by a three-coordinate measuring machine; Gear detectors, special cam detection equipment, etc. complete the measurement of workpieces with complex geometric shapes. Therefore, for enterprises engaged in the production of workpieces with complex geometric shapes, the quality control enterprises that complete the above products not only need to configure general measuring equipment, such as three-coordinate measuring machines, general standard measuring tools and measuring instruments, but also need to configure special testing equipment, such as each Various sizes and types of gear-specific testing instruments, cam testing instruments, etc. This often leads to the need for the measurement department of the enterprise to configure multiple types of measurement equipment and professional testing personnel engaged in measurement operations. The utilization rate of the measurement equipment is low, and the enterprise bears higher training costs for the measurement personnel and the use and maintenance costs of the measurement equipment; Flexible and general metrological detection cannot be achieved.
Therefore, it can reduce the measurement cost of the enterprise, the training cost of the measurement personnel, the use and maintenance costs of the measurement equipment, and achieve the purpose of improving the measurement and inspection efficiency, so that the enterprise has the real-time quality control ability of the production process, which will be related to the enterprise in the market activities. The ability to adapt to changes plays an important decisive role in helping enterprises establish and maintain a good market reputation.
