[0002] Wire cutting machine tools belong to the category of electro-discharge machining. Its main working principle is to use a moving (molybdenum wire, copper wire or alloy wire) as the electrode wire. Relying on the pulsed electric spark discharge between the electrode wire and the workpiece, when the heat generated by the discharge of the metal cutting wire is greater than the melting point of the workpiece material, the high temperature generated by the metal cutting wire melts or vaporizes the workpiece, forming a cut, and thus achieving the purpose of cutting the workpiece.

[0003] Currently, due to its characteristics such as high machining accuracy and fast cutting speed, wire cutting processing technology is widely used in the cutting processing of metals. When cutting a workpiece, the metal cutting wire is generally installed on the upper wire frame and the lower wire frame. The workpiece is clamped on the workpiece clamping fixture, and programmed on the numerical control system. The metal cutting wire is electrified, and the workpiece is driven to slide through the numerical control system, and then the product is cut.

[0004] However, the cutting angle of the existing wire cutting machine tools is usually relatively single, and the moving direction of the workpiece is mainly horizontal or vertical movement. Therefore, it is usually only possible to cut a vertical end face on the workpiece, while some inclined surfaces or chamfers on the workpiece cannot be cut and processed.
