Abstract: Since the shear stress is the main parameter influencing the energy requirement in machining, the estimation of this stress remains one of the principal problems in the theory of chip formation. ...

Abstract: A theoretical analysis of the high-speed shear in chip formation is based on a simplified model of the flow zone. Formulas for the shear stress and strain rate are developed. The data available ...

Abstract: This paper presents metal-cutting data for the high-speed machining of copper and aluminum, each at two levels of purity, and over a range of workpiece temperatures from −326 deg F (80 deg ...

Abstract: Variations in machining characteristics accompany differences in microstructure in resulfurized free machining steels. In this paper a relation between machining properties of this class of steels ...

Abstract: The process of chip formation in copper and aluminum single crystals has been examined with a scanning electron microscope. The morphology of the shear planes clearly illustrates that the actual ...

Abstract: The chip formation process during metal cutting in which the cutting velocity is permitted to decrease freely is examined from an experimental standpoint. Metal cutting data are obtained from ...

Abstract: The primary purpose of this series is to provide a review of significant technical literature published about materials processing up to the end of 1968. On the Fiftieth Anniversary of the ...

Abstract: In this paper, studies of incipient chip formation when cutting annealed 70/30 brass under orthogonal conditions are presented. Cutting forces were recorded and changes in deformation occurring ...

Abstract: An AISI 4340 Steel (325 BHN) was machined at various speeds up to 2500 m/min (8000 SFPM). Longitudinal midsections of the chips were examined metallurgically to delineate the differences in ...

Abstract: Single electrical discharges were produced on Fe and Zn electrodes under conditions similar to Electro-Discharge Machining (EDM). Crater morphology and surface texture were studied by means of ...
