Numerical control programming has its own "language" just like computer programming. The difference is that now the computer market takes Microsoft Windows as an absolute advantage. None of the CNC systems has an absolute advantage, which means that the CNC systems are not compatible with each other for a while. Therefore, when we want to use CNC machine tools, we must first know what kind of system the machine tools we already have.

 

Numerical control programming is widely used in the machinery manufacturing industry. It usually includes analyzing part patterns and determining the machining process; calculating tool trajectories and obtaining tool position data; writing CNC machining programs; making control media; proofreading programs and first piece trial cutting.

 

 

 

 

 

 

Introduction to commonly used CNC software

 

CNC (machining center) is rapidly popularized in the field of machinery, and computer modeling has become a must-learned skill for machinery and mold practitioners. The reality has also proved that a technician who understands graphics and programming will earn much higher than his peers with the same technical level. Therefore, it is necessary for us to understand relevant knowledge in this area.

 

Now in the CAD/CAM industry, UG, Cimatron, PRO-E, Mastercam, CATIA, CAD...

The system has been widely used in machinery, electronics, aerospace, scientific research, and mold industries. CIMATRON and MASTERCAM are used in 99% of machining programming. In the early days, these two softwares were used to draw pictures and write numerical control programs, but the functions of drawing modeling were not very good. PRO-E entered mainland China at this time.

 

3. Pro/E is a software developed by PTC (Parameter Technology Co., Ltd.) in the United States. It has become the most popular 3D CAD/CAM (computer-aided design and manufacturing) system in the world for more than ten years. It is widely used in various industries such as electronics, machinery, molds, industrial design and toys. It integrates multiple functions such as part design, product assembly, mold development, CNC machining, and modeling design. It became popular in mainland China in 1997. It is used for mold design, product drawing, advertising design, image processing, lighting design, and can automatically generate engineering drawings. At present, most companies have Pro/ENGINEER software installed. It and UG are both the best drawing software, but PRO-E is more popular in mainland China. Drawing with PRO-E, processing with UG and Cimatron has been recognized.

 

 

4. Mastercam is the most commonly used software in the Pearl River Delta. It first entered mainland China. 70% of the factory's CNC masters use MASTERCAM. It integrates drawing and programming. It has a fast line drawing structure and a good zoom function.
