Embodiment Construction

[0034] First, some relevant features of the HS-WECDM machine are explained and illustrated by means of figures. figure 1An exemplary high speed reciprocating wire cutting machine 1000 is shown including a base 106 on which a column 101 is mounted. The beam 102 is mounted at the column 101 on a Z mount, indicated by the dotted line Z, so that the upper wire guide head 112 can be positioned vertically. A lower wire guide arm 103 carrying a lower wire guide head 113 is fixedly mounted at the cylinder 101 . The X mount 104, the Y mount 105, and the stage 110 are serially mounted on the base 106, so that the workpiece 2 mounted on the stage 110 can move in the X / Y plane. A working tank 120 with a splash guard 121 surrounds the gantry to collect the electrolyte. The wire is stored on a wire spool assembly 10 . In known manner, the wire is unwound from the drum 10, travels through the wire travel line, and is then rewound onto said drum. The figure illustrates a conventional rec...

Abstract

A method for high-speed wire cutting is disclosed. A high-speed wire electrochemical-discharge cutting method (HS-WECDM), in which a work piece is processed by means of a wire electrode, in which consecutive negative polarity pulses are applied at the wire electrode, thereby at least partially developing discrete electrical discharges, characterized in that the method further includes, applying positive polarity pulses at the wire electrode between the negative pulses, and that an ignition occurring with each positive polarity pulse is immediately detected, and that the positive polarity pulses are immediately interrupted.

Description

technical field [0001] The invention relates to a method for electrochemical discharge cutting of wire rods, in particular to a pulse forming method for high-speed wire rod electrochemical discharge cutting. Background technique [0002] Wire Electrical Discharge Machining (WEDM) is a non-traditional process for accurately cutting conductive materials. The desired contour is cut in the workpiece with the aid of a wire electrode. The wire and workpiece are moved relative to each other according to the instructions of the machining program. The treatment is performed by applying a pulse voltage between the workpiece and the wire, causing a spark discharge at the space (gap) between the electrodes. [0003] WEDM processing is versatile and extremely precise, so WEDM machines are widely used, especially for producing dies and punches for stamping. WEDM processing is performed with the workpiece submerged in a bath of dielectric fluid or using an in-line rinse (mainly deionize...
