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

How to choose a five-axis machining center for aluminum alloy parts

To say what is suitable for the processing technology of aluminum alloy parts, it must be non-five-axis processing technology. Compared with the traditional three-axis four-axis machine tool, the five-axis processing technology has obvious advantages, and its accuracy is higher. The processing speed is faster and it saves more tools. However, there are currently a large number of five-axis machining centers for aluminum alloy parts on the market. How should we choose?

1. Structure determines equipment performance

Five-axis machining centers have various structures. The structural design of the machine tool determines the performance of the equipment on the basis of the machine tool, and determines the rigidity, accuracy, stability, operability of the machine tool, and so on. The following aspects should be considered: one is that the linear axis is not combined and superimposed when moving, the other is that the equipment with a short cutting circuit has good rigidity, the third is whether the tilt rotation axis is a DD motor, and the fourth is whether it is 5-axis linkage and 5-axis proximity, etc. .

2. Interference and collision avoidance

Interference avoidance is a problem that cannot be ignored in 5-axis machining. In addition to the use of computer-side software interference checking, the standard machine tool should also have the online real-time simulation CSG function to prevent interference even in manual mode. The online real-time simulation CSG function can check possible tooling errors or tool length setting errors before processing so as to reduce the emergency stop during operation to a smaller limit.

3. Rotation center correction

Changes in the rotation center caused by environmental and temperature changes will affect the five-axis machining accuracy. It should be automatically corrected by the probe. The 3-axis/index/5-axis machining accuracy verifies that the machining error of the tool is less than ±4μm. In order to ensure this, it is recommended to use the probe to automatically calibrate the 5-axis rotation center, and its linkage accuracy is a manifestation of multi-factor results.

Of course, the processing technology is also a key factor, which determines whether the performance of the equipment can be exerted to a greater extent. For example, our common use of special-shaped tools can greatly improve the processing efficiency. In addition, we all must pay attention to that is that the machining accuracy of the machine tool is directly affected by the accuracy of the rotation axis.
