工序图自动生成技术是 CAPP系统开发的难点之一，本文在分析汽车冲压件工艺特点的基础上，将大量的工序内容抽象为若干个操作元素进行处理，并对图形有效性检验、工序有效性检验和图形预处理等方面进行了研究，最后实现工序图形的自动生成。
The automatic generation technology is one of the difficulties in CAPP system development. Based on the analysis of the process characteristics of automotive stampings, this paper abstracts a large number of process elements into several operating elements for processing. The validity of the graphic inspection, Inspection and graphic preprocessing and other aspects of the study, the final realization of the process graphics automatically generated.
