ANALYTICAL STUDY OF RAKE ANGLE AND TOOL–CHIP FRICTION BEHAVIOUR IN ORTHOGONAL METAL CUTTING
The friction generated between the cutting tool and the work piece is a critical area of study in machining research, as metal cutting involves three major deformation zones: the primary shear zone responsible for chip formation, the secondary shear zone on the rake face where complex tool work piece interaction occurs, and the tertiary zone associated with ploughing and flank contact. Although various analytical, semi-analytical, and numerical models have been developed to study machining behavior, accurate material model parameters and the friction coefficient between the tool and work piece remain essential inputs. Based on literature studies, the friction behavior in metal cutting operations was analyzed using a thermo-mechanical cutting model that considers both sticking and sliding regions on the rake face. The study quantitatively examined the relationship between sliding friction and apparent friction coefficients, identified sliding friction coefficients for different tool work piece combinations through cutting experiments, and investigated the influence of total, sticking, and sliding contact lengths on cutting mechanics. The effects of varying cutting conditions on friction coefficients and contact lengths were also evaluated. In this work, uncoated carbide and coated carbide cutting tools were used to machine aluminum work pieces at cutting speeds ranging from 600 m/min to 1200 m/min with a constant depth of cut of 2 mm.
Furthermore, the experimental results related to rake angle and friction behavior during turning operations were optimized using the Taguchi method, where an appropriate orthogonal array was selected to minimize the number of experiments, and the significance of process parameters was analyzed using Minitab software.
