Abstract

The invention discloses a linear cutting energy consumption prediction method based on geometrical characteristics. The method comprises the following steps that firstly, a two-dimensional CAD drawing, a part material and the thickness of a pre-machined part are input, a basic database is called, and the material coefficient eta C, the thickness coefficient eta H and the speed coefficient eta S are determined; secondly, a machining drawing is determined according to the CAD drawing, the characteristics are decomposed, and according to the geometrical characteristics, the part characteristics are decomposed into the idle wiring characteristic, the instant cutting-in characteristic, the linear cutting characteristic, the arc cutting characteristic and the angle characteristic; thirdly, the time required by all the characteristics is worked out; fourthly, the energy consumption of all the characteristics is worked out; fifthly, the energy consumption of each part is worked out; and sixthly, the total energy consumption is obtained through accumulation. According to the linear cutting energy consumption prediction method, the required total energy consumption can be predicted through the two-dimensional CAD drawing, the part material and the thickness.

Description

【Technical field】 [0001] The invention relates to the technical field of energy consumption prediction, in particular to the technical field of a wire cutting energy consumption prediction method based on geometric features. 【Background technique】 [0002] Wire cutting is a processing method that uses a continuously moving thin metal wire (called an electrode wire) as an electrode and performs pulse spark discharge on the workpiece to remove metal and cut into shape. When wire electric discharge cutting works, a pulse discharge is carried out between the electrode wire and the workpiece. The electrode wire is connected to the negative pole of the pulse power supply, and the workpiece is connected to the positive pole of the pulse power supply. When an electric pulse comes, a spark discharge is generated between the electrode wire and the workpiece, and the temperature in the center of the discharge channel can be as high as 10,000°C instantaneously. The high temperature wil...
