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

Three commonly used compensation methods for CNC machining and mold machining

1. CNC machining tool length compensation

The concept of tool length is an important concept. When programming a part, the programming center of the part must be specified first, and then the workpiece programming coordinate system can be established. It is just a workpiece coordinate system, and the zero point is generally on the workpiece. The length compensation of CNC machining is only related to the Z coordinate. It is not like the programmed zero point on the X and Y planes, because the tool is positioned by the spindle taper hole without changing, and the zero point of the Z coordinate is different. The length of each knife is different, for example, we have to drill a hole with a depth of 50 mm, and then click the tap with a depth of 45 mm, which has 250 mm and 350 mm taps respectively. At this time mm, the machine tool has set the workpiece zero point. When the mold processing is changed to tap tapping, if both tools are processed from the set zero point, the tap is too long, because it is longer than the drill, which will damage the tool and the workpiece.

2. Tool radius compensation

  • The concept of tool radius and compensation is just like using different tool path lengths as compensation. Basically, you don’t need to consider choosing the length of the tool yourself when programming. Because of the tool radius compensation, we can do it at the same time when programming. Did not consider too much tool diameter size. CNC machining tool length compensation is applicable to all tools, while tool radius compensation is generally only used for milling cutters.
  • Offset compensation: When the machining center is processing small workpieces, the fixture can accommodate multiple workpieces at a time. The programmer does not need to consider the zero point of each workpiece coordinate when programming, but program according to the respective programmed zero point, and then Use the fixture offset of CNC machining to move the programmed zero point on each workpiece of the machine tool. Just as tool length compensation and radius compensation allow programmers to cover tool length and size, fixture offset allows programmers to use fixture offsets regardless of the location of the workpiece fixture.
