The significance of wide application of CAM technology

What is CAM? CAM is computer-aided manufacturing (Computer Aided Manufacturing). So far, CAM has two concepts: narrow and broad. The initial narrow concept of CAM refers to all production preparation activities from product design to processing and manufacturing. It includes CAPP, NC programming, calculation of working hours quotas, formulation of production plans, formulation of resource demand plans, etc. However, today, the narrow concept of CAM has even been further reduced to Numerical Control Technology, which is a technology that uses computers to control machine tools' movements in digital instructions, that is, CNC programming.

1. Development background

The 21st century is a period of rapid development and widespread application of information technology, and advanced manufacturing technology has become the development of the manufacturing industry. CAM technology originated in developed countries in the 1960s, and the development of CAM technology has always been closely related to CAD technology, because CAM technology directly uses CAD data information to realize CNC programming. Today, CAM technology has become the core foundation of advanced manufacturing, and its development and application have become an important symbol of measuring a company's progress and industrial modernization.

Before CAM technology became popular, programmers could only use manual programming and then field operations to determine whether their programming was safe and effective. Programmers need to go through various steps such as part pattern analysis, process plan, numerical calculation, writing program sheets to program verification before completing programming. Manual programming can only be used when the parts have simple shapes and short machining programs. Once you encounter parts with complex shapes, such as parts with non-circular curves, list curves and combined surfaces, or parts with not only complex shapes but also long machining programs, the programmer's work efficiency will become lower during the manual programming process, and it is prone to errors compared to automatic programming, and even collision events may occur, causing immeasurable losses.

With the rapid development of modern industry, CAMTechnology has been widely used in aircraft, automobile, machinery manufacturing, household appliances and electronic products manufacturing. Especially as the accuracy requirements of the automotive and aerospace industries are becoming more and more complex in the shapes, traditional design and manufacturing methods can no longer meet the current requirements. At this time, CNC milling becomes more and more important. Before CNC milling processing, the application of CAM technology became an indispensable link.

Therefore, the application of CAM technology can avoid many limitations of manual programming, which are reflected in the following points:

(1) Since the existing CAM software functions are quite mature, the work of CNC programming has been greatly simplified, and the requirements for programmers' technical background and creativity have been greatly reduced, creating favorable conditions for the popularization of this technology.

(2) Since CAM software is a system software formed by the computer's rapid computing, large-capacity storage and data processing capabilities, as well as rich graphics and text conversion functions, programmers can use its processing simulation functions to avoid major safety accidents, so programming safety is still worthy of belief.

(3) After so many years of supplementation, CAM software will come with dozens of general tooling methods, such as isometric processing, surround processing, projection processing, cycloid processing, NURBS unreasonable sample interpolation milling, etc., which are easy to learn to understand and flexibly use.

(4) During the CNC milling process, the basic cutting condition equation is established in the CAM software in advance. According to the parameters measured by the measurement system and the working conditions of the machine tool, the feed rate, cutting force, cutting speed, cutting operation sequence and coolant flow are adjusted. Under the conditions of the surface finish and machining accuracy of the parts, the machining efficiency, tool wear and energy consumption are better.

3. Summary

Using computer-aided manufacturing of parts and components can improve the ability to adapt to product design and variety, improve processing speed and production automation level, shorten processing preparation time, reduce production costs, and improve product quality and labor productivity in mass production. Due to the application of CAM technology, it provides strong guarantees for the initial trial production of Haery Company's project. In the future, we will focus on project needs to more actively explore the wider and deeper applications of CAM technology, and provide customers with faster and better quality services.
