Abstract
The invention discloses a wire cut electrical discharge machining energy consumption prediction model based on machining parameters. The modeling is divided into five parts, specifically, a total energy consumption model of a wire cut electrical discharge machining machine tool, a relation model of surface roughness and machining electrical parameters, a calculation model of the size of a removedworkpiece, a relation model of a material removal rate of a pulse system and the machining parameters, and a relation model of average power of the pulse system and the material removal rate of the pulse system are established, and finally, the total energy consumption model of the wire cut electrical discharge machining machine tool is obtained by combining the five parts. According to the model,machining energy consumption and machining time can be accurately predicted through the energy consumption prediction model in the process design stage, the setting of the machining parameters can beoptimally selected before producing and machining, so that the aims of finally reducing energy consumption and improving energy efficiency are achieved, and the model has certain theoretical and practical significance in a wire cut electrical discharge machining industry.
Description
【Technical field】 [0001] The invention relates to the technical field of wire electric discharge machining, in particular to the technical field of a method for predicting energy consumption of wire electric discharge cutting based on processing parameters. 【Background technique】 [0002] Studies have shown that industry consumes a large amount of energy and resources and imposes a huge burden on the environment. Worldwide, the energy consumption of the industrial sector accounts for 37% of the total energy consumption and 17% of carbon dioxide emissions, and this data shows a rapid upward trend. Among them, as a non-traditional processing method, WEDM has great advantages in processing materials with complex geometry and precision, so it is widely used in aerospace, automotive, medical, tool and mold manufacturing and other industries. However, compared with the traditional processing method, the energy consumption of WEDM is greater, and the energy consumption can be attr...
