在IBM 486 PC机上，用PROLOG语言开发了轴对称零件多阶段冷锻工艺设计专家系统，该系统由用户界面、材料数据库、规则库和系统外壳组成。特别是，将规则库与系统外壳分离，使开发的专家系统在处理各种几何图形时更加灵活。本文利用所开发的专家系统进行了若干工艺设计。

AN EXPERT SYSTEM FOR MULTI-STAGE COLD FORGING PROCESS DESIGN OF AXI-SYMMETRIC PARTS IS DEVELOPED USING PROLOG LANGUAGE ON IBM 486 PC. THE PROGRAM IS COMPOSED OF USER INTERFACE, MATERIAL DATABASE, RULE-BASE, AND SYSTEM SHELL. IN PARTICULAR, THE RULE-BASE WAS SEPARATED FROM THE SYSTEM SHELL TO MAKE THE DEVELOPED EXPERT SYSTEM MORE FLEXIBLE IN HANDLING VARIOUS GEOMETRIES. SEVERAL PROCESS DESIGNS HAVE BEEN CARRIED OUT USING THE DEVELOPED EXPERT SYSTEM IN THE PRESENT PAPER.
