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

Analysis of the Influence of Engine Speed ​​in Automobile Air Conditioner

 

The car air conditioner controller should be able to control the evaporating temperature, superheat, compressor speed, electronic expansion valve opening, evaporator fan speed and car interior temperature at the same time according to certain performance indicators. Unlike household air conditioners, the speed of the car air conditioner compressor changes with the speed of the car engine.

The cooling capacity of the car air conditioner is greatly affected by the engine speed. Therefore, the car air conditioning control system is a multivariable control system. The coupling relationship of various control parameters affects the quality of the car air conditioning control system. Therefore, it is very important to design a controller with a simple precompensator to decouple the coupling system of the car air conditioner.

Air conditioning system is mainly composed of compressor accumulator, expansion valve and other equipment. In the traditional semi-mechanical control system, the constant-capacity compressor controls the start and stop of the compressor through the electromagnetic clutch according to the evaporation temperature, and the thermal expansion valve reduces the pressure of the high-pressure liquid refrigerant to the evaporation pressure, so that it can be vaporized and absorbed in the evaporator. Heat, and it can also control the flow in the evaporator.

Traditional fixed-capacity compressors and expansion valves can no longer meet the requirements of high-efficiency and energy-saving automatic control. Therefore, it is necessary to study the control system of car air-conditioning with a new actuator. It adopts a multi-variable control strategy, and uses a variable speed compressor and an electronic expansion valve to comprehensively control the evaporation pressure and superheat.

In the experiment, a variable-speed compressor was simulated by a constant-capacity compressor driven by an AC motor, and an electronic expansion valve driven by a stepping motor was used for the experiment.
