英文摘要	The characteristics of serrated chips were analyzed using the theory of shear-slipping deformation at high speed cutting, with geometric and mathematic models of the chip built. Deformation of continuous chip for scissile metal materials can be analyzed and controlled by analogous methods that are employed at normal cutting speed. Geometrical model about serrated chip for difficult-to-cut material under orthogonal cutting condition is offered by proper simplifying. The nonlinear equations of indices related to some factors for measuring deformation degree of chip have been ascertained. Based on the condition fo forces equilibrium with respect to single serrated chip at the moment when it is to be in shear instability, forces equilibrium equations are obtained, with shear force and shear velocity as well as friction force and flowing velocity for a chip segment found. Finally, energy equations of cutting are acquired from deformation energy and friction work consumed in the course of chip formation, which can be offered to the further study of mechanism of high speed machining and the design of high speed machine tool.
