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

Five-axis processing of plastic parts How to ensure the quality of processing?

Five-axis processing of plastic parts is a more commonly used form of processing now. It can process complex-shaped parts that ordinary machine tools cannot process. However, when using five-axis processing, you also need to master the corresponding technology, otherwise you will be processing complex parts. Quality problems are prone to occur when

1. Compile the tool program

Although the tool length compensation function in five-axis machining is still effective, the tool radius compensation is invalid. This is because the ISO file does not provide enough data to recalculate the tool position. Therefore, in order to ensure reliable machining quality, it is necessary to compile different programs for different diameters of the tool when performing five-axis machining.

2. Use post processor

The difference between five-axis and three-axis machine tools is that there are two rotating coordinates on the five-axis machine tool and the tool position is converted from the workpiece coordinate system to the machine tool coordinate system, and the coordinates need to be changed several times in the middle. With the help of the current popular post processor generator, the post processor of a three-axis Cnc Machine tool can be generated only by inputting the basic parameters of the machine tool. For five-axis CNC machine tools, there are currently only some improved post-processors and the post-processors of five-axis CNC machine tools need to be further developed.

3. Solve the problem of nonlinear error and singularity

The kinematics of five-axis machining after the introduction of rotating coordinates is much more complicated than that of three-axis machine tools. One of the main problems related to rotation is the nonlinear error and it belongs to the programming error. In order to avoid this error, the programmer cannot know the size of the nonlinear error in the pre-calculation stage. Only after the machine tool program is generated by the post processor, the nonlinear error It is possible to calculate the error.

Although five-axis machining has more advantages than ordinary machining methods, in order to avoid the inefficiency of the entire machining process and the unsatisfactory quality of the machining, when using the five-axis machining of plastic parts, everyone should program the tool first. After that, we must make good use of post-processors and solve problems such as non-linear errors.
