仿真观察渐开线齿廓展成

Unfolding Process of Involute Tooth Profile by Simulation Observing

当前计算机辅助设计与辅助制造已成为了现代制造技术中的一项关键技术;采用Visual Basic6.0驱动AutoCAD 2000实现了齿轮加工的仿真;采用参数法建立了齿轮毛坯及齿条插刀模型,并在齿轮毛坯上记录齿条插刀的加工痕迹,这样可清楚地观察到渐开线齿廓展成加工的过程。

The current computer-aided design and manufacture become a key technology in a modern technique of manufacture.In this paper Visual Basic6.0 is used to actuate AutoCAD 2000 to realize the simulation of the gear processing.We can use the parameter method to establish gear semi finished materials and the rack slotting tool model,and record the processing trace of the rack slotting tool on the gear semi finished materials.In this way we can observe the unfolding process of the involute tooth profile clearly.
