What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

The control problem of electronically controlled clutch

  The automatic clutch of the vehicle can automatically perform the separation and combination operation according to the driving conditions of the vehicle and the driver’s intention to realize semi-automatic shifting. The control performance of this clutch directly affects the longitudinal comfort and fuel economy of the vehicle. Therefore, studying the control problems of electronically controlled clutches has important industrial application value. Generally speaking, the control of the clutch has to solve two problems: one is the coupling law of the clutch; the other is the actuator tracking the coupling law. Therefore, the entire controller is divided into an upper-level controller and a lower-level controller. Shen Shuiwen and others discussed the upper-level controller to solve the problem of the coupling law of the clutch. Due to the non-linearity, time lag, external interference, parameter perturbation and other influences in the system itself, it is difficult for the lower-level controller to track the clutch engagement law. In this paper, a sliding mode variable structure controller is designed, which adopts switching function leading compensation method to reduce chatter vibration. Motor-driven clutch actuator modeling DC brushless motor position servo system, which includes two controllers, an inner loop and an outer loop. The inner loop system is a pulse width modulation power inverter controlled by a sinusoidal current; the outer loop is a variable structure The controller is used to generate control signals and input the inner loop. In the figure, x is the reference displacement of the clutch release bearing, which represents the ideal coupling law of the clutch, which is proposed by the upper controller, that is, the clutch controller; the DC brushless servo motor is a three-phase permanent magnet synchronous motor. It is worth mentioning that the diaphragm spring plays an important and special role in the clutch. Due to its special structure, it also functions as a separation lever and a compression spring. At the same time, its special non-linear characteristics can reliably transmit torque after the friction plate of the driven disc is worn, and make the pedal easy to operate.
