PROBLEM TO BE SOLVED: To provide a numerical control device capable of high-precision machining in wire-cut electric discharge machining on a free curve shape approximated to a very small segment or a very small circular arc.SOLUTION: A numerical control device moving a wire electrode and a workpiece relatively to each other and machining the workpiece in accordance with a machining program of the present disclosure, comprises: section division means generating section data obtained by dividing a machining route commanded by the machining program into sections each having a sufficient distance; re-approximation means generating re-approximation section data obtained by re-approximating each section to either a straight line or a circular arc on the basis of the section data; and machining adjustment means adjusting a motion of the wire-cut electric discharge machine in corner portions and a circular arc portion of the machining route on the basis of the re-approximation section data.SELECTED DRAWING: Figure 5 |
