YHCAPP系统工艺信息提取和工序图生成技术研究

Research on Process Information Selection and Process Flowsheet Creating in YHCAPP

YHCAPP系统是面向中小企业的工具型CAPP系统,如何从CAD图形提取工艺信息和生成工序图是该类系统的一个难点。文中给出了一种基于表达式求值的方法,成功解决了该难题,实际应用表明该方法稳定可靠。该方法也为一般的工具型CAPP系统提供了新思路。

YHCAPP system is an instrumental CAPP system oriented to middle or small enterprises. Its key question is how to select process information and create process flowsheet from CAD drawing. A method based on arithmetical expression evaluation is provided, which has successfully resolved the above question and has proved its correctness and credibility. The method also provides a new way of thoughts for general instrumental CAPP system.
