Title:
ワイヤ放電加工装置、及びワイヤ放電加工方法
Document Type and Number:
Japanese Patent JP5077433
Kind Code:
B2
Abstract:
Based on a discharging gap value and machining allowance value stored in a corner-control-information storing means 20, a speed-ratio calculating means 23 being 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 means 24 calculates a machining feed speed at the corner portion based on a volume ratio calculated by the speed-ratio calculating means 23, and then outputs to a servo amplifier 8 on the basis of the length of a pre-corner section outputted by a pre-corner-section calculating means 21 and the length of a post-corner section outputted by a post-corner-section calculating means 22, instructions about machining feed speeds from entering the pre-corner section till getting out of the post-corner section.
