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 on 3D-product model can enhance the corporate efficiency among product design department, process design department and tooling design department for turbine disk.
