Abstract

PURPOSE:To machine a corner part with precision without diminishing a machining speed by a method wherein the suspension time of impressed pulses is controlled so that the density of machining energy may be constant in proportion to the change of machining area. CONSTITUTION:In a wire cut electric discharge machining etc. to finish the propile and the shape of a work during relative movement of a wire electrode 2 to the work, when the electrode 2 changes its advancing direction, the area of a machining part 3 (the oblique line part) decreases the instant its direction changes. In order to prevent abnormal machining at a corner part 5 by the change of this machining area, under a fixed feed speed of the electrode the change of the machining area caused by directional change is calculated in advance as a function of changing angle to advancing direction, electrode feed speed, machining groove width etc. and the suspension time is controlled according to the machining area so that the density of machining energy may be fixed. Thus, a high precision machining can be acomplished without lowering machining speed.
