【摘要】 人机界面是CAD系统中沟通使用者和系统之间的桥梁,其设计对系统的使用和维护有很大影响。这里针对蜗轮滚刀的设计要求,就蜗轮滚刀CAD系统的人机界面与容错性能进行了设计,采取必要的容错处理技术,利用可回复操作、良好的出错信息和纠错处理以及提供用户引导的交互方式等措施来提高系统的容错能力,保证了系的可靠运行。更多还原

【Abstract】 Human - computer interface acts to be anintermediumthat communicates betweenusers and systeminCAD system. And it has a great effect on use and maintenance of the system. In this paper, aiming at the demands of the worm hob, the human - computer interface and the fault - tolerant capabil y is designed. The system runs reliably by taking measures SUGh as adop ting necessaryfault - t01erant processing technique, making use Of recoverable operation, favorable enor information and correcting process, and providing introductory alternation mode to users.更多还原
