The invention discloses a numerically-controlled machine tool rough machining technological parameter optimization method based on main shaft current analysis. After optimization is conducted, it is guaranteed that the over-cutting phenomenon does not occur on workpieces in the whole machining process conducted according to a numerically-controlled program, it is guaranteed that a cutter is in a steady-working state with a maximum safe load all the time, the numerically-controlled program with the optimal material removal rate is generated, and the quality of the numerically-controlled program is improved; the load-carrying state of the cutter is optimized in the machining process, impact of a mutation load to the cutter can be reduced, and the service life of the cutter can be prolonged; a G code program with the highest efficiency can be generated after optimization, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of numerically controlled machine tools, and more specifically relates to a method for optimizing process parameters of numerically controlled machine tools for rough machining based on spindle current analysis. Background technique [0002] In the process of CNC machining, the reasonable selection of cutting parameters is of great significance to the improvement of production efficiency and machining accuracy and the reduction of production costs. For example, in the CNC machining process of the mobile phone case, due to the constant changes in the cutting conditions during the machining process, in order to achieve the maximum production efficiency and economic benefits, the feed rate F should be optimized to ensure that the workpiece does not overcut during the machining process. Under the premise, the optimized NC program can not only ensure that the tool is in a safe working state at all times, but also...
