With the development of science and technology, people pay great attention to the manufacturing industry, design, manufacturing level, product quality, cost and production cycle. In the decades since the emergence of CAD and CAM technology, the relationship between computer and machining production has become closer and closer. The technology that leads to the adoption of CAD and cam has become the focus of the current and future technological development of the entire manufacturing industry. Today, let's talk about the software application of CAD and CAM technology.
CAD and CAM technology has gone through the era of mainframe, minicomputer, workstation and microcomputer. There are popular cad/cam software at that time in every era. Now, workstation and microcomputer platform cad/cam software has occupied a dominant position, and there have been a number of excellent and popular commercialized software.
1. High grade cad/cam software
Representatives of high-end CAM software include Unigraphics, I-DEAS /pro/engineer, CATIA, etc. This kind of software is characterized by superior parametric design, variable design and feature modeling technology combined with traditional solid and surface modeling functions. It has complete processing methods, accurate calculation and strong practicability. It can process extremely complex workpiece surfaces from simple 2-axis processing to 5-axis linkage, and can automatically control and optimize the NC processing process, At the same time, it provides secondary development tools that allow users to expand the functions of UG. It is the preferred cad/cam software in aviation, automobile and shipbuilding industries.
2. Mid range cad/cam software
Cimatron is the representative of mid-range cad/cam software. This kind of software has strong practicability, providing a relatively flexible user interface, excellent three-dimensional modeling, engineering drawing, comprehensive NC machining, various general and special data interfaces, and integrated product data management.
3. Relatively independent cam software
Relatively independent cam systems include Mastercam, SURFCAM, etc. This kind of software mainly obtains the geometric model of products from other CAD systems through neutral files. The system mainly includes interactive process parameter input module, tool path generation module, tool path editing module, 3D machining dynamic simulation module and post-processing module. It is mainly used in the mold industry of small and medium-sized enterprises.

In CNC machining, the selection of cad/cam software has a great impact on machining. If the requirements of products are not high, but choose high-end software, it will not only waste resources, but also increase the cost of enterprises; If you choose ordinary software with high product requirements, it will lead to poor product quality. Therefore, operators engaged in NC machining should have a certain understanding and understanding of the classification, characteristics and scope of application of the software, and choose the software reasonably according to the production situation.
