摘　　要：涡轮盘是航空发动机的重要零部件之一,通常采用拉刀拉削加工涡轮盘榫槽部位。传统的拉刀设计方法是根据设计与工艺需求采用绘制二维工程图图样的方法,这种方法设计周期长,且不易更改。为此提出了MBD工艺模型驱动的涡轮盘榫槽拉刀设计方法,通过构建涡轮盘的MBD拉削工艺模型和涡轮盘榫槽拉刀模型模板,提取出涡轮盘MBD拉削工艺模型中的参数并将其与涡轮盘榫槽拉刀模型模板相关联,驱动涡轮盘榫槽拉刀模板生成相应的拉削刀具,从而实现MBD工艺模型驱动的航空发动机涡轮盘榫槽拉刀设计,缩短了设计周期,提高了设计效率。The turbine disk is one of the important parts of the aero-engine. Mortise broach is usually made by broaching process. In the traditional broach design method, according to two-dimensional drawing and designing and process requirements, the parts are made. If this method is used, the design cycle is longer and it is not easy to change it. So, the design method of aero-engine mortise broaches driven by MBD process model is proposed in this paper. The MBD broaching technological model of the turbine disc and the template model of the turbine disc tenoning broach model are constructed, then the parameters in the MBD broaching process model of the turbine disc are extracted, which are associated with the turntable tongue-and-groove broach model template and used to drive the turntable tongue and groove broach template to generate the corresponding broaching tool so as to realize the MBD technology model-driven aeroengine turntable tongue and groove broach design, thus shortening the tongue and groove broach design cycle and improving the tenon broach design efficiency.
