摘要:A generalized mechanical model is proposed to predict cutting forces for five-axis milling process of sculptured surfaces with generalized milling cutter, which is considered as a revolution around tool axis of an arbitrary section curve composed of variable lines and curves. Solid-analytical-based method is presented and extended to precisely and efficiently identify the cutter-workpiece engagements between the generalized milling cutter and workpiece being machined. And the undeformed chip thickness is calculated with respect to pre-defined tool coordinate system, which is regarded as the transformation form of feed cross-feed normal system by lead and tilt angles. Although only two experimental validations (peripheral milling with cylinder end mill and multi-axis milling with ball end mill) are performed to estimate the robustness and flexibility of the method presented, it can be applied for an arbitrary mill geometry in multi-axis milling as well as three-axis milling, two-and-a-half-axis milling. Finally, a case study of aero-engine impeller five-axis milling with ball end mill is performed to further illustrate the validation of the model.
