FMS中CAPP与CAM集成技术的研究

Inberation of CAPP and NC Programming in FMS

介绍了一个适用于ＦＭＳ的ＣＡＰＰ／ＣＡＭ集成系统．它由创成法ＣＡＰＰ系统、ＮＣ自动编程系统和它们之间的接口等主要部分组成．系统采用基于特征的零件描述方法作为集成环境下统一的零件信息模型．由ＣＡＰＰ系统生成的工艺规程，通过接口文件自动传输给ＮＣ编程系统，经过特征识别后，从特征ＮＣ程序库中调用相应的特征数控程序，实现ＮＣ自动编程．为检验ＮＣ程序的错误，系统还具有刀具轨迹仿真功能．系统用户界面友好，经加工验证，可用于生产．

The develop￣ of an inmptal C￣/NC prognlnming sySthe in FMS isdescribed. The systhe is made up of a genelahve CAI,P and NC auto-programmingspsthe and the interfveen there A fears-based method is ed for padsdiction to build up a consistal model for infonnation on partS under an inoptalenvironment. The CAPP system is provided for the genelation of process plans ofparts. In the NC programming spstem,a set of standard NC proguim of features arebuilt into a NC program library. By ￣us of the data tlansfer interfaCe file, the syStemcan can up NC proglaim for the features from the library in armrdanee with thepine plan of the part, to reachs NC proglalnming automation. The spstem isptovided for the simulation function of tool path to cheCk up mistakes in NCprograms. This spsteln has ho abet in actual production and it is shown that it beapplied in manufacturing practice.
