At present, with the continuous development of modern science and technology, the more traditional model production methods such as manual model and parts processing can not meet the actual development requirements. In CNC processing, the preparation of processing software is the basic work, but the preparation of CNC processing software is usually very complicated, and the programming workload for the production of complex workpiece and single part is very heavy, resulting in low production efficiency. Therefore, the combination of CAD/CAM software and CNC processing technology can save a lot of design and production time, and improve the precision and speed of parts processing, greatly promoting the development of manufacturing industry.
1.1 NUMERICAL control machining technology
The current NUMERICAL control processing technology is a variety of technology combination, including: mechanical processing technology, computer technology, electronic technology, automatic control technology and detection technology. This is a new type of machinery production technology, rapid development in the machinery manufacturing industry to play an important role. CNC machine tools and CNC production machinery that focus on CNC technology represent the most advanced automation integration technology.
1.2 CAD/CAM technology
CAD is computer aided design. This technology can process the model of CAM parts and meet the design requirements. When judging the performance of CAD system, it is mainly based on its design function and whether it can be designed effectively. Nowadays, automatic design and interactive design are the most widely used CAD technologies. Although automatic design has high working efficiency, it is not flexible enough and can only be used for standardized production with fixed product structure. Interaction design has greater flexibility and can better show the creativity of employees, but this approach is less efficient.
