<p>A numerical control device has an X axis along which a turret (906i) to which a plurality of tools (9061i, 9062i) are mounted is moved, a Z axis along which a workpiece (W) is moved, and a B axis which is a center line perpendicular to the X axis and the Z axis and about which the turret is rotated, and also has at least one of an H axis which is a center line perpendicular to the center line of the rotation about the B axis and about which the turret is rotated and a C axis which is a center line parallel to the Z axis and about which the workpiece is rotated. The numerical control device includes a means for performing virtual Y slanted plane machining. During a virtual Y axis slanted plane machining mode in which the tools are moved along the X, Y, and Z axes relative to the workpiece on the basis of an X-Y-Z axis movement instruction in a machining program, the means for performing virtual Y slanted plane machining slants the tools such that the center axis is perpendicular to a slanted plane slanted from the X axis and the Z axis, and moves the tools relative to the slanted plane along the Y axis.</p> |
