Milling Force Analysis and Modeling of Super-Alloy GH2132

Abstract:

Iron-based alloy GH2132 is a kind of difficult-to-machine material. In this study, the experiments were processed to research the effect of feed per tooth, axial cutting depth and radial cutting depth on milling force. Variance analysis was made on the three factors. The results reveal that axial cutting depth affects milling force significantly, followed by feed per tooth and radial cutting depth has little influence on it. Two types of empirical model of milling force were established by the result of orthogonal experiment and multiple linear regression analysis. It was verified that both (h_m, a_p) model and (h_m, a_p, a_e) model had good prediction accuracy compared with the experimental data. By calculating specific cutting force using the (h_m, a_p) model, a modified coefficient of the specific cutting force for 1mm² chip cross section was proposed. The study would provide guidance to improve the machining precision and machining efficiency of high temperature alloy materials.
