本文介绍了一个重型齿轮的CAPP系统。该系统依据重型齿轮的特点，采用半创成式的思想，自动对重型齿轮进行加工方法的选择、加工顺序的排定、刀具、机床和切削用量的选择及轮齿加工的挂轮计算等一系列工艺工作，生成完整实用的工艺文件。系统已在工厂应用。
This article describes a heavy duty gear CAPP system. Based on the characteristics of heavy duty gear, the system automatically adopts the idea of semi-creation, selects the processing method of heavy duty gear automatically, arranges the processing order, selects the tool, machine tool and cutting dosage, Series of workmanship, to generate a complete and practical process documents. System has been applied in the factory.
