Research of CNC Automatic Programming Method Based on Process Database

摘要

In this paper, a method of NC process information extraction and import to template file based on Process Recording Files and database was proposed, which provides an effective way for NC process information sharing and reuse, and made positive effect on current situation in CNC manufacturers, such as: type of product is relative stable, process of CAM programming has lots of duplication, process parameters are dependent on programmers, the processing quality is instable and so on. The Process Recording Files are from mainstream heterogeneous CAM softwares, such as: PowerMILL, UG/CAM, which used to record CAM programming process, macro files from PowerMILL and UG/CAM are belongs to this kind of file.
