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

Analysis on the Research of Automobile Liquid Nitrogen Drive System

Regarding the research of automotive liquid nitrogen drive system, there are mainly the following aspects.

System circulation research: LN2000 system and CoolN2Car system are the representatives of current liquid nitrogen driving system circulation research. Both are circulation systems that only use liquid nitrogen as the energy storage medium. The working principle is to use liquid nitrogen as the working fluid in the open Rankine cycle, exchange heat in the ambient air heat exchanger, and perform work in the expander.

The main components of the LN2000 system are: low temperature Dewar, cryogenic pump, main heat exchanger, economizer, expander, etc. But the efficiency of the system is only 0.2miles/gallon (about 85km3), and the speed is low, only 22miles/h (about 35.4km/h).

The principle of the LN2000 circulation system is: the liquid nitrogen is sent from the low temperature Dewar to the economizer (preheater) by the cryogenic pump. After being heated by the discharged nitrogen in the economizer, it enters the main heat exchanger, is heated by air, and the pressure rises. High, enter the expander to do work. The exhausted nitrogen returns to the economizer to heat the liquid nitrogen.

LN2000 system and CoolN2Car system are all circulating systems that use liquid nitrogen as the energy storage medium, but they face the following three problems:

①The energy is only provided by the ambient air, and the heat exchange rate is slow;

②The surface of the heat exchanger is easy to be frosted;

③It is highly dependent on the external air environment. Therefore, from a practical point of view, such a system has low power, slow speed, and unstable operation.

Research on the expansion process: The research on the expansion process, theoretically, the specific work* obtained by isothermal expansion is greater. Isothermal expansion is to keep the temperature of the expanding gas constant during the expansion process, but such an expander is difficult to design. The actual isothermal expander has not yet been manufactured. Therefore, there is research on the quasi-isothermal expansion process.
