企业信息化东风汽车公司 CAD/CAM应用已经有了近二七年的历程。80年代初,自行开发了《交互车身设计CAD系统SUMS》。 80年代中后期开展了锻造模具、铸造模具及注塑模具的CAM工作。1986年起引进二维CAD软件并进行二次开发。1990年在产品设计部门实现彻底甩掉图版。1995年引进Pro/ENGINEER软件。该系统的引进,使技术中心的CAD/CAM技术应用水平上了一个的台阶,也使企业的设计水平上了一个新的台阶。 应用效果 东风汽车公司花费比二维CAD软件数十倍的价钱建立三维CAD系统,充分… 相似文献

本文对工作在63-64GHz频段的异步码分多址(A--CDAM)蜂窝系统的特性进行了分析研究,并同工作于传统频带(低于2GHz)的CDMA系统进行了比较,得出结论为:应用63-64GHz频段能够极大地改善系统的通信容量,如果在系统设计时考虑到足够的功率储备以克服降雨衰落的影响,这个频带作为CDMA蜂窝系统或个人通信网络的通信频率是十分合适的。 相似文献

CAD (Computer Aided Design) has now become an integral part of Technology Education. The recent introduction of highly sophisticated, low-cost CAD software and CAM hardware capable of running on desktop computers has accelerated this trend. There is now quite widespread introduction of solid modeling CAD software into secondary schools but how much is really known about the processes of learning and teaching CAD, particularly solid modeling? This paper will discuss current practice in CAD teaching and the way this relates to solid modeling. It will discuss the findings of current research with particular emphasis on the difference between command knowledge and strategic knowledge and how this relates to the development of CAD expertise. Command knowledge is referred to as knowledge of the commands (algorithms or tools) and the procedures to use those tools within CAD software while strategic knowledge is concerned with knowledge of the alternate methods by which a specific task may be achieved and the process by which a choice may be made. The results of a recent experimental study into the teaching of CAD expertise will then be outlined and the implications for the teaching and learning process will be discussed. 相似文献

This article examines the impact of CAD/CAM on the UK clothing industry. It questions the extent to which computerisation has led to a greater choice over production strategy and argues that upskilling has not occurred. 相似文献

Continuous innovations in product and process technology, coupled with time-to-market pressure, have made rapid product development a key strategic objective of manufacturing firms. Consequently, many firms have started to define the ways in which products are designed, developed and produced, so as to reduce the time from conception to manufacture. The strategies employed to achieve this goal vary, and include the integration of functions through selective use of concurrent engineering, the formation of strategic project teams, and technological connections by CAD/CAM systems. The research reported in this paper, co-ordinated by the WZB Institute of Berlin, is aimed examining organizational, technological and human resources practices that enhance quality in R&D by improving communication and co-operation C&C) between the actors. Although the research was carried out in four countries(Germany, Italy, Japan and the USA) and in three sectors (car, personal computer and machine tools) this paper analyses the evidence provided by a set of face to face interviews of the managers, engineers and designers of a European car producer. 相似文献
