STATISTICAL EVALUATION OF CUTTING FORCE COMPONENTS AS A FUNCTION OF CUTTING EDGE RADIUS SIZE FOR MILLING OF AUSTENITIC STAINLESS STEEL AISI 316L

This study investigates the impact of cutting edge radius on cutting forces during machining of AISI 316L with uncoated cemented carbide tools. Four cutting edge radii were tested, each with three tools. Milling was conducted with different parameters for roughing and finishing. Cutting forces were measured and analyzed into tangential and radial components. Statistical evaluation using linear regression and analysis of variance assessed the influence of edge radius, machining conditions, and interactions. Results showed that both edge radius and machining conditions significantly affect cutting forces, providing insights for optimizing tool selection and improving tool life under various conditions.
