基于操作与精铸模特征的工艺规程设计

The Process Planning of Refine Casting Mould to Turbine Blade Based on Feature and Operation

涡轮叶片精铸模具工艺规程设计是一项典型的强经验弱理论性工作,将工艺设计专家经验知识化,是解决该问题的较好途径。系统采用基于精铸模特征与操作的设计思想,为精铸模零件典型特征建立数据库,将专家经验知识化,缩短精铸模工艺规划周期,增强模具产品的经济时效性。

The process planning of refine casting mode to turbine blade is a difficult job which needs more experience. Using expert system to translate the experience into knowledge is a good way to solve this problem. By the thought of expert system and operation, the feature database for refined casting mould is established and, which can enhance the efficiency and shorten the time of developing cycle.
