Abstract

The invention discloses a novel numerical control wire-cut electrical discharge machining method and a novel numerical control wire-cut electrical discharge machining device. The numerical control wire-cut electrical discharge machining device is at least configured with a numerical control X axis, a numerical control Y axis and a numerical control Z axis; a wire electrode is provided with a horizontal cutting section and a vertical cutting section; after a workpiece is clamped once and when the workpiece is processed by utilizing the horizontal cutting section, if the wire electrode in the horizontal cutting section is set to be parallel with the X axis, a straight grain profile, around the X axis, of the workpiece is cut through the linkage of the numerical control Y axis and the numerical control Z axis; if the wire electrode in the horizontal cutting section is set to be parallel with the Y axis, a straight grain profile, around the Y axis, of the workpiece is cut through the linkage of the numerical control X axis and the numerical control Z axis; when the workpiece is processed by utilizing the vertical cutting section, a straight grain profile, around the Z axis, of the workpiece is cut through the linkage of the numerical control X axis and the numerical control Y axis. According to the novel numerical control wire-cut electrical discharge machining method and the novel numerical control wire-cut electrical discharge machining device disclosed by the invention, without turning over the workpiece, the precise complicated straight grain profile of the workpiece can be cut in two vertical and horizontal directions, and therefore, a workpiece turnover process is not needed, a workpiece turnover error is avoided, and the machining precision is improved.

Description

technical field [0001] The invention relates to the field of electric machining, in particular to a method and device for wire electric discharge cutting. Background technique [0002] CNC WEDM device (machine tool) uses the principle of EDM, uses metal wire (electrode wire) as the processing electrode tool, applies pulse power (copper wire, molybdenum wire) between the workpiece and the electrode wire, and is controlled by the computer. Predetermined trajectory and the detection data of the processing state control the relative movement between the workpiece and the electrode wire, and a kind of electric processing machine tool for cutting and processing through the controllable pulse discharge between the two electrodes. The discharge area needs to be adjusted during processing. The flushing works to remove the erosion material and cool the workpiece wire electrode. [0003] In the existing CNC WEDM device, the electrode wire in the wire feeding system is only provided wi...
