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

How to lock the solenoid valve from power off in the automobile control system

In the A4LD automatic transmission, when certain situations occur, the electronic control unit de-energizes the lock-up solenoid valve and releases the lock-up clutch. These situations include: the engine cooling water temperature is below 53℃ or above 116℃, the throttle valve is completely closed, the throttle valve is suddenly opened or closed, the accelerator pedal is pressed hard or the throttle valve is fully opened, and the intake manifold vacuum is low. When the engine speed is lower than the set value, and when the car is braking.

Specifically, when the engine cooling water temperature is lower than 53°C, the lock-up clutch will not be locked, so that the engine can be fully warmed up and can withstand the work load smoothly; when the cooling water temperature is higher than 116°C, the same will not happen. The purpose of locking is to reduce the load on the transmission system and help cool the engine. When the cooling water temperature is within the normal range, the electronic control unit will pay close attention to the electric signal sent by the throttle position sensor. Unlock the clutch during the throttle period to reduce engine emissions and improve fuel economy: If the signal indicates that the throttle valve is open or fully open, the electronic control unit will also notify the lock solenoid valve to de-energize for faster Accelerate the vehicle and utilize its unique torque-increasing effect in the torque converter. The purpose of disengaging the lock-up clutch even when the throttle valve is opened and closed suddenly and briefly is to prevent the lock-up clutch from repeatedly operating during this period. Correspondingly, in the electronic control unit, the memory program can ensure that after a slight change in the throttle position, the action of the lock-up clutch is delayed for a period of time.

The electronic control unit in the system also pays close attention to the engine speed signal provided by the ignition sensor and the intake manifold vacuum signal provided by the intake manifold absolute pressure sensor. When the engine speed drops below the determined function value at a low vacuum, the electronic control unit will notify the lock solenoid valve to de-energize, so as to ensure that the torque converter changes from fourth gear to third gear without locking the torque converter. Downshifting of gears, in order to obtain the best shifting smoothness and softness.

In addition, in any case, as long as the electric signal from the brake switch indicates that the driver is braking, the control unit of the electronic control system will also notify the lock solenoid valve to de-energize to prevent damage to the engine during sudden braking.
