Abstract
An apparatus for generating numerical control (NC) information automatically determines a division point if two steps are required for machining a part member, and produces NC information for each of divided portions, thereby reducing the time taken to prepare NC information for overall machining. The apparaus includes a division point determination unit for determining a division point between first and second steps based on a material shape, a part shape and a jaw shape supplied: a part shape division unit for generating a first step part shape and a second step part shape based on the division point, the material shape and the part shape: and a material shape division unit for generating a first step material shape and a second step material shape based on the division point, the material shape and the part shape. The numerical control information for the first step is formed from the first step material shape and the first step part shape, while the numerical control information for the second step is formed from the second step material shape and the second step part shape.
