 Abstract: The purpose of this study is to explain the experimentally observed variations in cutting parameters during the machining of single-crystal materials. Fundamental relationships between crystal plasticity and machining are developed. The workpiece anisotropy stem from crystallographic differences are explained with a rate-insensitive Taylor plasticity model. A brief discussion of the applicability of Schmid-based models to machining processes is also presented. The periodic variations with changing crystal orientations observed in experimental studies are explained with the results of the proposed model for machining. The friction between the rake face of the tool and the material is introduced to the existing model. The applicability of concepts like Texture Softening Factor and Effective Taylor Factor in previous works are discussed. The specific energy of cutting is related to Taylor factor for better understanding of crystallographic effects.
