【Abstract】 The design manufacture and application of replaceable carbide profile finish milling cutter are described with the example of nuclear power groove 2270-091092 fir tree blade root finish milling cutter. It mainly includes the design of the circumferential distribution of the blade,the calculation and optimization of the blade body and parameters,the determination of the number of teeth,the helical direction and the rotation angle of the cutter,and the modeling verification. The precision of the profile of the replaceable finish milling cutter developed in this project has completely reached the level of imported milling cutters,which can greatly save the cost of enterprise blades and bring remarkable economic benefits.更多还原
