Description

1. Technical field

[0001] The invention relates to the numerical control machining technology of complex curved surfaces such as arbitrary curved surface impellers in the technical field of mechanical processing and numerical control machining, in particular to a drum-cone cutter and a method for side-milling complex curved surfaces using the drum-cone cutter. 2. Background technology

[0002] At present, the cutters usually used in the finishing of centrifugal impellers are spherical cutters, which have a small effective cutting radius and low processing efficiency.

[0003] C.Y.Wu.(Arbitrary surface flank milling of fan, compressor, and impeller blades.Transactions of the ASME, Journal of Engineering for Gas Turbines and Power, Vol.117, 1995, p534~p539), proposed the use of conical cutter side milling arbitrary curved surface The method of impeller blades, the cutting edge of which is conical, see figure 1 . He broke through the way of thinking that spherical cutters or ...
