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 rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Study car vibration and noise

Studying the vibration and noise of automobiles and taking effective measures to control them has also become extremely complicated. At present, effective control measures have been taken to control the internal noise of gasoline and diesel vehicles, while the problem of identifying and controlling noise sources of new energy vehicles such as hybrid vehicles, electric vehicles, and fuel cell vehicles will become a problem for researchers. New subject. Each test will provide effective feedback to optimize the design at this stage. These verification tests and design optimization are repeated to determine the structure of the catalytic converter.

Taking a fuel cell prototype vehicle as the research object, through the experimental analysis of its acoustic and vibration characteristics in the anechoic chamber, the main frequency components of the noise in the vehicle under static and different uniform speed conditions and the corresponding noise sources and their transmission methods are obtained. The corresponding vibration and noise reduction schemes are proposed.

Introducing the noise sources in the car The vibration and noise generated by the driving motor assembly, power steering pump, air-conditioning compressor, fuel cell auxiliary system moving parts (such as hydrogen pump, fan) and cooling water pump of the fuel cell prototype vehicle studied are inside the car The main source of noise. Among them, the drive motor assembly, power steering pump, air-conditioning compressor, and fuel cell cooling water pump are arranged in the front compartment, and the hydrogen pump and fan are arranged in the luggage compartment. Because the prototype car borrows the traditional engine front car body, the rear part of the body does not adopt sound insulation measures, when the fuel cell power system is working, the occupants in the rear seats obviously feel a low “buzzing” roar, and the rear seats The noise is significantly higher than the front seats.
