FIG. 2 is an explanatory diagram showing a method of cutting off a workpiece in a conventional wire cut electric discharge machining method. In the figure, 1 is a wire electrode of a wire cut electric discharge machining apparatus, 2 is a workpiece, and 3 is a wire electrode 1. The machined groove 4 is formed halfway into the workpiece 2, and the machined groove 4 is formed so as to straddle the machined groove 3.
This is an auxiliary board that is adhered to with adhesive 5.

Since the conventional electrical discharge machining method is configured as described above, the adhesive 5 flows into the machining groove 3,
Since it is also bonded at the processed groove 3, it is difficult to peel off when cutting off the cut portion 7 after cutting, and since the adhesive 5 remains on the processed surface of the cut portion 7,
There were problems in that the part to which the adhesive 5 was attached was discolored and that extra effort was required to remove the adhesive 5.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory cross-sectional view of one embodiment of the present invention. In FIG. 1, before attaching the auxiliary plate 4, the processed groove 3 is filled with water-based glue 6, which is a soluble filler. Thereafter, an adhesive 5 is applied to the auxiliary plate 4, and the plate is bonded to the workpiece 2 so as to straddle the processing groove 3. Since the cutting process begins after the adhesive 5 dries, the water-based glue 6 packed in the grooves 3 is washed away by the process fluid, and the process surface is cleaned.
