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

Verify the reliable simulation algorithm to simulate and calculate the dual-drain pipe radiator

 

Porous media conditions: model parameter method of porous media for calculation. The numerical simulation result table lists the simulation data of the heat sink with the wave distance of the heat dissipation band. The radiator simulation data shows the numerical simulation results of the overall temperature field of the tube-belt radiator when the wave distance of the heat dissipation belt is at the water inlet flow rate and the air inlet speed. Result comparison and conclusion analysis The error comparison between the experimental data and the simulation results of the radiator with a wave distance of the heat sink The distance radiators have been processed as shown in the table.

The numerical simulation results of the radiator are in good agreement with the wind tunnel test data, where the maximum error of the outlet water temperature is and the maximum error of the wind resistance is. The errors between the test data and the simulation results mainly come from two aspects. On the one hand, the inevitable errors caused by the test equipment, test methods, and data collection in the heat transfer wind tunnel test of the radiator are caused by the radiator numerical simulation. Errors caused by assumptions and simplifications in the calculation of its physical model. Although there are certain errors, the accuracy of this simulation algorithm can already meet the needs of actual engineering, and it has certain reference value for the future research on the fluid flow and heat transfer mechanism inside and outside the tube-belt automotive radiator. Performance comparison of double drain pipe and single drain pipe radiator. Simulation results. The core of double drain pipe radiator is made of aluminum; the core is high, the air inlet speed, the water flow rate, the water temperature, the water temperature, the air temperature, the air temperature, and the heat dissipation. Wind resistance temperature, inlet air speed, inlet water flow rate test, outlet water temperature simulation, outlet temperature error test, wind resistance simulation wind resistance error year, width and thickness respectively; the number of heat dissipation water pipes is; the number of heat dissipation bands is the double drain pipe type heat dissipation water pipe row is row, water pipe The outer side is wide, the wall of the water pipe is thick, and the water pipe is long; the wave height, wave distance, and thickness of the heat dissipation belt are as follows. The window opening angle of the heat dissipation belt is simulated and calculated using the proven and reliable simulation algorithm for the double drain pipe radiator.
