现代cad发展（Modern CAD development） Modern mechanical design using CAD Technology Keywords: mechanical design; CAD Technology Abstract: the introduction of CAD technology in mechanical design, can solve the repetitive mechanical design of multi enterprise information resource utilization rate is low, shorten the cycle of product development, has great economic benefits and application prospects. 1 development of CAD Technology CAD (Computer Aided Design) is a computer aided design English abbreviation, is the use of the powerful graphics processing ability and numerical calculation ability, support the design and analysis of engineering and technical personnel for the project or product, to achieve the desired objective, and achieved a technological innovation. Since the birth of computer aided design (CAD) technology in 1950, it has been widely used in the fields of machinery, electronics, architecture, chemical industry, aeronautics and Astronautics, energy, transportation and so on. The design efficiency of products has been improved rapidly. Now the computer aided manufacturing technology (Com-puter Aided Manufacturing, CAM) and product data management technology (Product Data Management, PDM) and computer integrated manufacturing system (Computer Itegrated manufacturing system, CIMS) in one set. Product design is the study of the fate of the product and the most important part. The design of the product determines the cost of the product 75%. At present, the CAD system has developed from an original CAD system with only numerical calculation and graphics processing capabilities into an intelligent CAD system (ICAD CAD) combining artificial intelligence technology (Intelligent). In twenty-first Century, ICAD technology will have new features and development directions to improve the rapid response ability of the manufacturing industry to market changes and small batch and variety requirements in the new era. The modern design technology and intelligent activities re
