Abstract
A predicted discharge gap g(n) and a predicted minimum gap gmax(n) between a workpiece ( ) and a wire electrode ( ) to prevent a short-circuit are added to the machining conditions, and read in doing a program check, and a predicted allowance for machining m(n) in the nth machining is calculated from the predicted discharge gap g(n), a correction amount y(n) of the wire electrode ( ) for the workpiece ( ) and a wire electrode diameter d, in which the predicted allowance for machining m (n) in the nth machining and the predicted minimum gap gmax (n) between the workpiece and the wire electrode to prevent short-circuiting in the nth machining are displayed on a display unit ( ).
