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

The application of frame assembly in the processing technology and integration of auto parts

Processing unit based on group technology We adopted the organization form of processing unit in the machining workshop in the technical transformation project of the relocation of an automobile chassis parts manufacturer. The company mainly produces independent suspension systems and brake parts. The original processing and production are divided into multiple workshops. Due to the limitations of the original site, the layout of the workshops is relatively scattered. The main production organization in the workshop is the cluster layout, resulting in production logistics Cross and roundabout, increase logistics costs. This time because of the opportunity of relocation and technical reform, the company hopes to expand its production capacity while improving its management level and gradually realize ERP management.

After analyzing the products and production process of the factory, it is found that the main processing parts of the factory, such as ball pins, spherical pins, joints, ends, etc., have structural, material similarity and process similarity, and they are large in quantity, suitable for group processing technology .

The analysis is now carried out with the production workshop of independently suspended lever arms. The workshop is divided into joint processing area, end processing area, spherical pin processing area, etc. according to the principle of similar parts structure and process similarity. Each district is divided into 23 processing units according to the production program of the product, which is beneficial for enterprises to replicate and expand their production capacity according to their own capabilities and market demand. Take the spherical pin processing as an example. The part blank is an outsourcing forging into the blank warehouse. The part processing consists of drilling the center hole (double-sided centering machine tool) y rough turning rod and ball (profiling lathe) y drilling (drilling machine) ) Y Finish turning the rod and ball (CNC lathe), and enter the warehouse after cleaning and inspection after processing. The layout of the machine tool for the spherical pin processing unit. This processing unit adopts a U-shaped layout.

This group of processing units can complete the annual production capacity of 100,000 pieces, and can be replicated with the expansion of the production program; the material carts are used for transportation between the processing units, and the logistics basically flows in the closed production unit. The processing of various machine tools The ability is relatively balanced, which can greatly reduce the waiting time; the operation of the CNC lathe adopts the way that one person takes care of two equipment at the same time, which improves the simultaneous care coefficient of the equipment. It can be seen that the adoption of this layout scheme has significantly improved logistics and reduced production costs.

After the transformation of modern production management based on group technology, the enterprise needs to implement ERP system to integrate enterprise resources and improve management level. Group production units are connected to the ERP system through information technology, which builds the foundation of modern management. As shown, the entire production management system is centered on ERP, and the scheduling management is based on the principles of /urgent priority 0/inventory * small 0. Processed parts use the product data management system to convert the information required by the ERP from the CAD system; the production management system interacts with the ERP data to determine the process route, man-hour quota and tools according to group technology or computer-aided process design (CAPP) to convert the parts The processing tasks are assigned to the corresponding processing units. As a result, the workshop plans to replace the original process management with the management of similar parts; the quality management is mainly transformed from the control of the inspectors to the automatic control of the processing unit; the worker is developed from one person, one machine to one person with multiple machine tools. As the basis of the flexible manufacturing system (FMS), the processing unit simplifies production planning and scheduling, and improves the flexibility and work efficiency of workshop production.
