基于复杂零件的数控加工工艺分析和宏程序编程

NC Machining of Complex Parts Based on the Analysis and Programming Instructions

主要论述了复杂零件的图样分析方法、确定复杂零件的工艺基准、加工方法和切削用量,以及编制铣削圆弧齿的宏程序。在数控加工中,由于零件复杂多样,特别是轮廓曲线的形状和位置千变万化,对具体的零件应灵活处理,制订出合理的加工方案。

This article mainly clahorated the complex components pattern analysis method, the determination complex components craft datum, the processing method and the cutting specifications, as well as estahlishnlent milling circular arc tooth great procedure. In numerical control processing, hecause components complex diverse, specially outline curve shape and position ever changing, should process nimbly to the concrete cnmponents, draws up the reasonable processing plan.
