With the application of computer technology in mechanical engineering design, computer aided design (CAD) has gradually replaced the traditional mechanical design method. The continuous development and improvement of CAD technology's own functions have also had a great impact on modern mechanical engineering design. The application of various design techniques, calculation techniques, design tools and even new materials and new processes in mechanical design and manufacturing has greatly and continuously reduced the monotonous mechanical work in the process of mechanical engineering design, and the creative thinking of designers has been liberated as never before. At the same time, the traditional theoretical system and method system have also been strongly impacted. CAD technology is an important part of advanced manufacturing technology, and it is the most influential high-tech application technology of computer technology in engineering design, machinery manufacturing and other fields. As a modern design method, CAD technology has untied many constraints for designers and created a convenient and fast design platform. People's minds are liberated, and the intensity of design work is much reduced, which is of great significance to the development of mechanical engineering design industry.

Main advantages of 1 and CDA technology in mechanical engineering design

1. Promote the digital upgrade of mechanical design

With the continuous progress of science and technology, the computer-aided design software system is constantly optimized and upgraded. Because the digital engineering of computer-aided design software is obvious, the production devices of mechanical equipment in mechanical manufacturing industry have gradually realized digital control and design. Therefore, computer-aided design technology promotes the digital development of mechanical design.

2. It is beneficial to shorten the design time of mechanical engineering.

Mechanical design is a job that needs a lot of time. Since the introduction of CAD technology, the mechanical design cycle has been greatly shortened. Because CAD three-dimensional mechanical design is conducive to solving complex geometric modeling problems. It can combine simple geometric entities into various complex geometric entities through Boolean operation and other functions, and can automatically generate intersecting lines and intersecting lines, which greatly reduces the design workload, shortens the mechanical design cycle by nearly half, and greatly improves the design and production efficiency. When using 3D CAD system to develop and design new machinery, only some parts need to be redesigned and manufactured, and most parts will inherit the previous information, which improves the efficiency of mechanical design several times. At the same time, the 3D CAD system has high variant design ability, and brand-new mechanical products can be obtained through rapid reconstruction.

3. It is beneficial to ensure the quality of mechanical products.

In mechanical design, the parameters of mechanical products in mechanical design are accurate and precise through some software systems in computer-aided technology system. In addition, the system model in the computer-aided design software system is precisely designed by computer software. In addition, the computer-aided design software system integrates mechanical system and structural optimization system, which makes the designed mechanical products not only accurate in design, but also scientifically guaranteed. Therefore, use a computer.

2. The concrete embodiment of 2.CDA technology in mechanical engineering design.

1. computer-aided drawing

Computer aided drawing is the earliest application of CAD technology in mechanical engineering design, and it is also the most basic function. Traditional manual drawing has a large workload, and the quality of drawing is affected by many external factors, so its accuracy and aesthetics are difficult to be guaranteed. Using the rich graphics library and drawing commands in CAD software, high-quality engineering drawings can be easily drawn. The printed drawings are neat and clear and easy to save. Computer-aided drawing can make the majority of draftsmen no longer need to draw at their desks for a long time, thus reducing the labor intensity of drawing work. At the same time, making full use of the graphic library and fully functional drawing commands in CAD software can greatly improve the efficiency of engineering drawing.

2.CAE mechanical software

The practical functions of CA E software system in mechanical engineering design mainly include: structural optimization design, engineering numerical analysis, kinematics/dynamics simulation, strength life prediction and design evaluation. In the process of design, the software of CA E system can't design the dynamic characteristics of products such as stiffness, strength, material, life, rationality, motion characteristics and structure, until the modeling problem of mechanical products is solved by CAD technology.

3. Applied to mechanical engineering design modeling.

Modeling is the most critical part in mechanical design. Three-dimensional modeling technology is the most widely used technology in computer aided design software. Among the three-dimensional models, wireframe model, surface model and solid model are three modeling technologies that are widely used. The most important design concept of three-dimensional design is to realize parametric and variable design of modeling design. In the traditional mechanical design technology, it is difficult to realize the three-dimensional processing of modeling technology. The computer-aided design software realizes the three-dimensional model processing of mechanical design modeling technology through the construction of some basic technical systems. In the computer aided design system, there are six modeling systems, namely, cube, sphere, cylinder and cone, in addition to rings and wedges. According to the design requirements, mechanical design engineers complete the mechanical model design by disassembling and assembling some different systems. However, in mechanical design, if you encounter some parts with complex design, you need mechanical design engineers to draw two-dimensional images of the parts first, then use computer-aided technology software to process these two-dimensional images in three dimensions, and finally establish a three-dimensional model of the parts. With the help of computer-aided technology software, mechanical design engineers can realize the accuracy and accuracy of parameters in mechanical design, make the designed model closer to the needs of real life, and finally minimize the errors in mechanical design.

Integrated manufacturing of molds in 4.CAD/CAM.

With the continuous application and update of CAD technology, the production equipment of machinery manufacturing industry has gradually changed from ordinary machine tools to CNC machine tools. Using CAD design technology, mold manufacturing can develop in the direction of digitalization and integration. The functions of CAD/CAM technology mainly include graphic editing, 3D drawing, simulation, finite element analysis of surface modeling, NC machining and dynamic display.

In a word, China's manufacturing industry is developing rapidly. In the future social development, informationization, automation and intelligence will surely become the main trend of all walks of life. It is very necessary to apply CAD technology in mechanical engineering design, and it also meets the requirements of the development of the whole social environment. Machinery enterprises should vigorously introduce and popularize CAD technology, actively expand its application scope in the field of mechanical design, and promote the modernization and intelligent development of machinery manufacturing industry.
