THE INVENTION Problems to be Solved] However, in the first conventional example shown in FIG. 9, when the two-dimensional machining shape WF is close to the outer periphery of the workpiece W 2, the table 1A
Fixed circumferential portion of the workpiece W 2, the wire electrode running in the vertical direction can not discharge machining by interference of said table 1A. Therefore, in this case, after the electric discharge machining of the machining shape WF of the workpiece W 2, except for the fixed circumferential portion rotates the workpiece W 2 by releasing the fixing,
As that process the raw portion from the fixed to the end of machining parts again table 1A of the workpiece W 2, were processed in several. However, each time for rotating the workpiece W 2, must redo the settings parallel out or machining origin of the workpiece W 2, is not suitable for those high accuracy is required, a problem that it takes time to set-up was there.
