The problem of disjointed design and manufacturing links, a method of seamlessly connecting Pro/Designer and Pro/Engineer in the product design process is proposed, which opens up a new way for the coherence of industrial product design and later engineering manufacturing. The process of design process provides effective measures for product design systemization, which shortens the product design and development cycle and realizes the systematic design of product design.

introduction
The design of the product is a combination of art, humanity, history, and nature. This design should use specialized image design software such as Coreldraw, Photoshop, Painter, 3DSMAX, ALIAS, etc. This type of software usually has no data restrictions and is relatively free and arbitrary. Product design is generally undertaken by art stylists.
The structural design of the product is a rigorous design. It requires accurate data and meets national or international standards. Each size and tolerance of the product is based on data and is not bad. This design is based on software designed for product structure design, such as: AutoCAD, UG, Solidedge, Pro/ENGINEER, SolidWork, etc. Although some high-end design software has already had the design and rendering functions of complex products, it is still not easy for art designers to master and use such software. Therefore, the designers who are engaged in structural design are mostly mechanical engineers. The thinking and methods of design are completely different from the stylists. Their thinking is a design thinking method that fully meets the mechanical design standards.
Then, how the two designs will be combined in the design of the product, and get a better combination, and better to complete the conversion from design to processing procedures? Become a problem we have to consider in product design.
1. CAD technology is applied to product design
As a new science combining engineering technology and aesthetic art, product design is a modern design method in modern industrial product design. It comes from the material production of society, and is closely integrated with human industrial production activities and daily life. With the improvement of human material life and cultural art level, product design has penetrated into all aspects of society, from household daily necessities, Household appliances, furniture, etc., to all kinds of production equipment, instrumentation, office supplies and various types of transportation, public facilities, etc., product design has become an indispensable part of modern industrial product design. Reasonable and beautiful design can attract more users in the market competition, strive for market share and create more economic value. Industrial products with good appearance, pleasant colors and comfortable surface texture can beautify people's living and production environment, enrich people's spiritual requirements and improve production efficiency [1].
Traditional product design, generally in the market research, after the development of the demand table, first expand the concept of the flat sketch, form a slightly complete plan, start to draw a three-dimensional sketch, after the final shape, then draw the effect map, three views as needed Or make a simple model. In the process of designing, engineers and technicians, product stylists and workers need to work together to express the designer's ideas with sample physical models. However, it takes a lot of labor to make physical samples for each type of solution. There are problems such as low precision, difficulty in modification and adjustment, long design cycle and high cost [2].
The development of computer technology has brought about the third wave of technological revolution. Computer aided design (CAD) technology is the most active computer in the industrial field. It integrates numerical calculation, simulation, geometric model processing, graphics, database management system and other aspects of the technology, the abstract, flat, separate design objects are embodied and visualized, it can pass the "virtual reality" technology The product shape, material, color, and even the processing process are fully expressed, and the product design process can be systematically and standardized through data management. This is the basis for the inevitable combination of industrial design and CAD technology.
2. The influence of CAD technology on product design
Computer-aided techniques and means for product design have not only broadened the field of computer applications, but also have a great impact on traditional design concepts and methods. The specific embodiment can be summarized in several aspects of product design.
2.1 Design performance display to “paperlessâ€
Computer-aided product design does not require a variety of traditional tools such as rulers, gauges, pens, papers, etc. The computer's operating platform provides inexhaustible space. The implementation process of the performance is the mouse click and keyboard operation, copying , modification, etc. can be completed in the past, and it is clean, simple and efficient. The emergence and popularization of digitizers and tabletes have enabled the design to break away from the traditional pattern of hand-painted handwriting in the creative sketching stage, thus creating a complete “paperless†design.
2.2 Design scheme exchange is convenient and fast
The development of the network has narrowed the distance between people. In the computer network, the designer and the client can communicate design ideas more conveniently, and can communicate with each other in the first place anywhere. In addition, the division of labor can be carried out through online resource sharing.
2.3 The overall design process is more flexible and efficient
On the computer, the creative solution of the product can realize the three-dimensional design through rapid three-dimensional modeling and rendering, and change and adjust the body feeling, shape adjustment, color, texture and so on. The traditional effect picture loses the original design. status. In the design, a lot of time and energy can be used in analysis, evaluation, and adjustment, so that the traditional design process has changed in the focus. At the same time, the contents of the computer are digital, and there is no loss in file copying. This way, other people can share the same design, and the design tasks can be completed in stages, by people, and by sub-sites, which greatly improves work efficiency [3].
2.4 Product development cycle is shortened, design results are more realistic and reliable
The increase in work efficiency has significantly shortened the product development cycle, and computer-aided manufacturing has greatly shortened the production cycle of the prototype. The results of computer-aided design have real stereoscopic effects and quality sense, especially the rapid development of digital technology, making virtual reality possible. Computer virtual reality technology can make static design results become virtual real world, people are in real products. Simulate the use of the environment to verify all aspects of product performance.
In the design of computer-aided products, the production process of the product can also be simulated by computer, which can greatly enhance the scientific and reliability of the production plan, and can timely detect and correct errors that are not easily noticeable in the design stage.
