Abstract

The invention discloses an efficient energy-saving optimizing method for numerical control milling processing process parameters based on a Taguchi method. The efficient energy-saving optimizing method comprises the following steps: analyzing characteristics of a numerical control milling processing process energy consumption time interval and establishing a numerical control milling processing energy efficiency function; designing orthogonal experiment by applying an orthogonal table in the Taguchi method, and adopting signal to noise ratio evaluation to obtain an interference relationship between process parameters and processing time as well as specific energy consumption; obtaining a regression equation of each target by adopting a response surface process, and establishing an efficient energy-saving multi-target optimizing model for numerical control milling processing process parameters; and searching out Paretro optimal solution through a particle swarm optimization. Correlation relationship of specific energy, processing time and process parameters in the processing process is analyzed through experimental data and algorithm optimizing results, so that a complex coupling mechanism between energy consumption efficiency and process parameters is disclosed in the numerical control milling processing process.

Description

technical field [0001] The invention relates to a numerical control machining process optimization method, in particular to a high-efficiency and energy-saving optimization method for numerical control milling process parameters based on the Taguchi method. Background technique [0002] The CNC machining system has a large volume and a wide range, and the energy consumption is huge but the energy efficiency is extremely low. In the actual processing process, process parameters not only affect the processing quality, cost, efficiency and other indicators, but also are closely related to energy efficiency issues. Reasonable process parameter selection is one of the important means to realize energy saving of machine tool processing system. Therefore, it is a basic scientific problem that needs to be solved urgently to optimize the process parameters of NC machining by comprehensively considering the energy consumption of machine tools and traditional goals.
