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 Find the Hole Center with a Meter?

We sometimes encounter some special-shaped workpiece to be processed, the edge of the workpiece is curve, no straight line.

 

In the first process of numerical control processing, this will not have an impact on our processing, but to the back of the process processing, irregular shape will let us in the workpiece points encountered trouble, so that the processing can not be normal down.

Even sometimes due to temporary process changes, the workpiece that has been processed in the first process may be scrapped, which wastes a lot of resources. Therefore, it is a very important part of the process to have a foresight of the process planning.

 

For example, in the workpiece machining in the figure above, because the workpiece is surrounded by curves, the only feature that can be used as the origin of the coordinate of the workpiece is the hole.

 

We want to choose a hole as the origin of the workpiece coordinates, the hole had better be the original existence of the workpiece, so that there will be no additional cost of more processing time; Hole processing is best to use the existing tool, which will reduce the cost of the tool; It is important that the position of the hole be accurate after the first process is completed.

 

After comprehensive consideration, we chose the hole in the lower right corner of the workpiece as the origin of the coordinate of the workpiece.

After the completion of the first processing procedure, due to the shape of the workpiece, we processed a slightly larger clamp in the soft clamp according to the shape of the workpiece, so as to better hold the workpiece. According to the design of the process, we need to find the center of this hole, which can be used as the origin of our workpiece coordinates.

 

The diameter of the machining hole and the requirement of position precision are not suitable for the use of edge finder, so we choose the calibration table to find the center of the hole.

The tools above all serve the same purpose — to find the center of the hole.

 

Although the installation of the calibration meter is different, the basic principle of operation is the same. In the following video, you can learn not only the details of how to do it, but also the good practices that will help you in your work.
