Embodiment Construction

[0010] See figure 2 , the cutting tool 10 used for cutting the blade boss features is a large-angle taper cutter, which includes a side conical surface 11 and a bottom R1 angle. Consistent with the R2 angle of the boss feature of the blade to be processed, the side conical surface is the cutting edge of the tool; the taper α of the side conical surface 11 is 15°; the surface of the side conical surface 11 is sprayed with a titanium nitride coating , so that the wear resistance of the tool can be greatly improved, so the number of blades that can be processed after each tool grinding is greatly increased, and the cost of the tool can also be effectively reduced. After adopting the cutting tool of the present invention, since the machining contact area between the cutting tool and the boss of the blade is greatly increased, the program efficiency is increased by more than 60%, and the number of blades that can be processed in a single grinding is increased from 2 pieces of the ...

Abstract

The invention provides a cutter for cutting machining of blade lug boss characteristics. The cutter is capable of solving easy-to-happen problems of long machining time, low machining efficiency, severe cutter wear, high production cost and low blade lug boss surface quality during the cutting machining of the blade lug boss characteristics by using a hard alloy ball-end cutter at present. The cutter is a large-angle taper cutter, and comprises a lateral conical surface and a bottom R1 angle, the two of which are in smooth transition and integrally connected with each other; the bottom R1 angle is consistent with an R2 angle of each blade lug boss characteristic to be machined in dimension; and the lateral conical surface is a cutting edge of the cutter.

Description

technical field [0001] The invention relates to the field of blade cutting tool design, in particular to a tool used for blade boss feature cutting. Background technique [0002] The feature of the blade boss is a three-dimensional curved surface in space. Because of its complex surface features, the boss features of the blade die forging blank are more and uneven than the surface allowance. In order to meet the finished product size of the boss features, the existing processing method mainly uses a carbide ball-end cutter to profil the boss features of the blade. Although this cutting method can better cut the boss features of various blades , but due to the large blank allowance of the boss feature, the dense tool path, and the low tool processing parameters of the boss part, the processing time of the boss feature will be long; in addition, due to the surface For point contact, its cutting parameters are low, the tool wear is serious, and the tool needs to be regrinded o...
