Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a process parameter optimization method related to energy efficiency and processing cost in numerical control processing. Background technique [0002] Modern CNC machining often adopts multi-step processing methods. Process parameters and the number of steps have an important impact on processing efficiency and processing costs. Some scholars have done related research on multi-step CNC machining efficiency and processing costs. Corresponding process parameters and number of steps to optimize the selection method. However, as the energy consumption of machine tools has attracted increasing attention, how to optimize the energy efficiency of the process parameters in the multi-step machining process is an urgent problem to be solved in the context of green manufacturing. [0003] Research on energy consumption is mainly focused on revealing the relationship between process p...
