Numerical control machine tool drilling process power, energy consumption and energy-saving control method

Abstract

The invention discloses a numerical control machine tool drilling process power, energy consumption and energy-saving control method. According to the method, the total power of the drilling process of a numerical control machine tool is decomposed into five parts, namely, a machine tool standby power part, a cutting fluid spray power part, a spindle rotation power part, a Z axis feed power part,and a material drilling power part; the power model of each part is established separately, so that the total power model of the drilling process can be obtained; a drilling time value is calculated through drilling depth and drilling speed; a drilling power consumption model is further obtained by multiplying the total drilling power and the drilling time; the power and energy consumption valuesof a plurality of drilling programs that are practical and feasible are calculated and evaluated according to the established total drilling power model and drilling energy consumption model, and an optimal drilling program of which the power value does not exceed a limit and of which the energy consumption is minimum is selected to perform practical cutting, and therefore, energy-saving control can be realized. The method of the invention is simple and practical, has high energy consumption prediction accuracy, is conducive to achieving energy-saving control, and is convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of energy consumption prediction and energy saving in the drilling process of a numerical control machine tool, in particular to a method for obtaining power and energy consumption in the drilling process of a numerical control machine tool and an energy saving control method. Background technique [0002] Research by the International Energy Agency shows that nearly 1 / 3 of global energy consumption and 40% of carbon dioxide emissions are attributed to manufacturing. A study by the Massachusetts Institute of Technology shows that the carbon dioxide emissions produced by a CNC machine tool running for one year are equivalent to the annual carbon dioxide emissions of 61 SUVs. As the key equipment in the manufacturing industry, CNC machine tools have significant energy consumption and carbon emissions. Therefore, the study of energy consumption prediction and energy-saving technology of CNC machine tools plays...
