End milling cutting force model considering tool path radius under partial engagement
Abstract
Abstract With the advancement of tool path planning, milling trajectories have evolved beyond straight lines. Since tool path geometry strongly influences milling forces, this study develops a unified prediction model incorporating both tool path radius and cutting width—factors often neglected in previous research. Based on geometric modeling, discretized cutting elements, and oblique cutting theory, the model achieves theoretical computation of milling forces under linear and circular paths. Simulation results show that path radius notably affects the magnitude and direction of milling forces, confirming the model’s accuracy and applicability. The findings provide theoretical guidance for optimizing tool path parameters in complex surface machining.
