A CAD/CAM SYSTEM USING A TECHNICAL KNOW-HOW DATABASE FORMETALLIC MOLD PLATES

摘要

The purpose of this research is to create a practicalrnCAD/CAM system manufacturing metal molds for plastic injection.rnIn this paper, a technical know-how database is built byrnholding expert’s technology as an object-oriented forms, and thernCAD/CAM system uses it automatically. Know-how of experts,rnsuch as decision of cutting speed tool path, and tool’s life,is accumulatedrnin the database. Anyone can get the same NC data asrntheir to be made by experts. Moreover,the lead time generatingrnNC data is decreased.
