Application of Computer Three-dimensional Drawing Technology in Automobile Parts Manufacturing

Abstract

With the rapid development of China's economy and society, people's living standards have greatly improved, and people's demand for travel quality has also increased. China is the largest car owner and has invested a lot of manpower and material resources in the car manufacturing industry. Auto parts are the various units that constitute the entire car and a product that serves the car. There are many types of auto parts. With the improvement of people's living standards, people buy more and more cars, and the auto parts market is getting bigger and bigger. In recent years, auto parts manufacturing plants have developed rapidly, and the manufacturing quality requirements of auto parts must also attract the attention of the entire society. We not only need to meet the quality of people's travel services, but also always ensure people's travel safety. This requires higher auto parts manufacturing technology, and efficient and precise manufacturing technology must rely on 3D CAD/CAM integrated software to achieve. The essence of 3D modeling technology is to construct a 3D model, especially a geometric model, based on the 3D spatial information of the research object, use related modeling software or programming language to create a graphic display of the model, and then perform various tasks and processing. In order to obtain the three-dimensional spatial information of the research object, appropriate algorithms are used and three-dimensional spatial feature points are set through computer programs. This article mainly uses relevant 3D software to study the advantages of computer 3D drawing technology in the R&D and manufacturing of modern auto parts. The research results show that after the application of three-dimensional drawing technology, the quality and efficiency of auto parts manufacturing will be improved accordingly.
