Abstract: In the present paper, the effects of the hardness, strength, chemical composition, microstructure, fracture properties of the material and other factors on the chips formation and deformation were studied during cutting the brittle metal. The process of cutting the brittle metal and the basic theory of the scrap fracture was also discussed comprehensively. In addition, this study pointed out the importance of the hot working process to avoid some metallographic organizations within the cast iron such as the stripy-like and inhomogeneous graphite.

Abstract: The experiment of ultrasonic assisted pulse electrochemical compound finishing is carried in this paper. The machining principle of the compound finishing is discussed in this paper. Processing experiments of compound finishing are carried out to study the effects of the main processing para- meters, including the particle size, the ultrasonic vibration amplitude, the minimum gap between the tool head and workpiece and the pulse voltage, on the material removal rate and the surface quality for hard and brittle metal materials. The curves of the corresponding relationships are also obtained. The study indicates that the processing velocity, machining accuracy and surface quality can be improved under the compound finishing, obtaining the processing technology conductions of the compound finishing.
