Design Method of Turbine Fir–Tree Blade Root Tenon Slot Broach
This paper studied the key issues of the broach structure design of turbine fir-tree blade root tenon slot, based on the analysis technical requirements of groove surface and the total margin. According to the principles of rough broach efficient, high precision broach qualitative to determine broaching method and broaching margin distribution. It proposed broaching methods of surface processing, broaching margin distribution and geometric parameters.
