Abstract
Based on a discharging gap value and machining allowance value stored in a corner-control-information storing means, a speed-ratio calculating meansbeing a machining-volume calculating means calculates machining volumes of a straight line portion and a corner portion to calculate a volume ratio therebetween. A corner-portion-speed calculating meanscalculates a machining feed speed at the corner portion based on a volume ratio calculated by the speed-ratio calculating means, and then outputs to a servo amplifieron the basis of the length of a pre-corner section outputted by a pre-corner-section calculating meansand the length of a post-corner section outputted by a post-corner-section calculating means, instructions about machining feed speeds from entering the pre-corner section till getting out of the post-corner section.
