CAD/CAM自动编程中零件造型的研究

在零件数控加工中,对零件加工造型是进行自动编程的基础,在CAD/CAM中进行的零件加工造型,虽然以零件设计造型为基础,但从表现形式上有自身的特点和要求。零件加工造型具有不同于零件设计造型的特点和要求,在自动编程中合理选择适当的造型方法,有利于高效、准确地生成符合要求的刀具路径,从而收到良好的效果。有时可根据零件的结构特点、加工工艺采用一些简化方法来进行建模,可缩短造型时间,降低造型难度,提高加工质量。

Automatic Programming and Simplicity CAD Mold Based on CAD/CAM

In component numerical control processing, is carries on the automatic programming to the component processing modelling the foundation, carries on the component processing modelling in CAM, although take the CAD in component design modeling as the foundation, but has own characteristic and the request in the manifestation. The part machining models have specific requirements and feature which are different from the part design models, choosing the appropriate modeling methods in auto - mastic programming is helpful to venerate the required tool path efficiently and accurately so as to obtain the fine operation effect. Sometimes may according to the component unique feature, the processing craft be possible to use some short - cut methods to carry on the modelling, may reduce the modelling time, reduces the modelling difficulty, improves the processing quality.
