生产信息化首先表现在先进的生产技术,它从设计、加工到装配都日益建立在知识密集的基础上。电子计算机辅助设计(CAD)平均可以提高工效三倍以上,而设计质量提高,又可使新产品一次成功率由过去的百分之三十至四十提高到百分之九十。电子计算机辅助制造(CAM)促使机电一体化全面实现。机电一体化首先是数控机床(NC),即用数字指令来控制机床动作的自动化机床,使机械加工实现单件自动化。在数控机床的基础上又发展了装有自动换刀装置
Production informatization first manifests itself in advanced production technology, which is increasingly based on knowledge-intensive design, processing and assembly. On average, computer-aided design (CAD) can improve ergonomics by more than three times, and the quality of design can be improved, which can increase the success rate of new products from the previous 30% to 40% to 90%. Computer-aided manufacturing (CAM) facilitates the full realization of mechatronics. Mechatronics First, the numerical control machine tool (NC) is an automatic machine tool that uses digital commands to control the movement of a machine tool, enabling single-piece automation of machining operations. On the basis of numerical control machine tools, automatic tool change devices have been developed.
