摘要
为有效解决涡轮盘榫槽拉刀设计周期长和效率低的问题,提出基于产品模型的榫槽拉刀快速设计方法。该方法通过特征识别和参数提取获得涡轮盘榫槽型面的加工特征参数,建立适应不同齿数的涡轮盘榫槽拉刀通用模板,通过参数关联将提取出的加工参数信息转化为拉刀设计信息,并驱动涡轮盘榫槽拉刀模型模板生成相应的榫槽拉刀。上述研究成果缩短了榫槽拉刀的设计周期,提高了榫槽拉刀的设计效率,并实现了涡轮盘设计部门、工艺设计部门、榫槽拉刀工艺装备部门之间基于三维产品模型的有效协作。
A rapid design method of mortise broaches based on product model was proposed to solve the problems of long designing cycle and low efficiency of mortise broaches.In this method,characteristic parameters were obtained by feature recognition and parameter extraction based on product model.3D parametric model templates were built to apply to mortise broaches with different numbers of teeth.Characteristic parameters were transformed to design information of broaches by parameter association.The model templates were driven to generate the broaching tools.The application of this method can shorten the design cycle of mortise broaches,reduce duplication of effort and improve design efficiency.Besides,the communication based on3D-product model can enhance the corporate efficiency among product design department,process design department and tooling design department for turbine disk.
