中文摘要：

将CAD技术与模块化技术相结合,开发了数控成形磨齿机模块化CAD系统。根据模块化设计原理,在功能分析的基础上划分机床的各级模块。以三维设计软件UG为开发平台,建立机床各级模块的参数化三维造型模板库,同时还建立了存放设计数据的数据库。用户在系统界面的引导下可完成设计过程中的模块选择、模块组合和设计计算等环节,从而实现数控成形磨齿机计算机辅助模块化设计。

英文摘要：

The modularization design CAD system of CNC gear form grinding machine was developed by combining CAD with modularization technology. According to the design principles of modularization, the modules of gear form grinding machine were divided on the basis of function analysis. Taking UG software as the developing platform, the parametric 3-D modeling module bank and a database were set up. Under the guiding of the system interface, users could complete such tasks as module choice, module combination, and calculation etc. Therefore, computer aided modularization design of CNC gear form grinding machine could be realized.
