Influence of blade curvature characteristics on energy consumption in machining process.

Saving resources and reducing the energy consumption of CNC machine tools has become one of the main research directions of modern green manufacturing. In this paper, the influence of curvature characteristics on energy consumption is studied based on surface milling. Firstly, the loss of energy consumption in the machining process of the NC machine tool is analyzed, and the milling energy consumption model per unit volume is established; secondly, based on the unit volume milling energy consumption model, a unit volume milling energy consumption model considering blade curvature characteristics is established; finally, based on the milling energy consumption model, the "specific energy" is introduced to establish the energy consumption field model of blade milling path. The distribution of the energy consumption field of four milling paths is analyzed in turn, and the distribution of the energy consumption field of 24 tool sites in the milling path is analyzed. The experimental results show that the energy consumption field model can show the energy consumption distribution of the NC machine tool machining process, and the accuracy is more than 90%, which provides a reliable basis for the subsequent energy consumption prediction of the impeller machining process.
