PROBLEM TO BE SOLVED: To improve work efficiency by arranging a calculating means for calculating such an area lower in a finishing height than a designated cutting area and excluded a worked part from a combined area of the cutting area and an adjacent area adjacent to the cutting area. SOLUTION: A central processing unit 1 for indicating a this time work area by an input device 2 selects an indicated this time work area, for example, an adjacent area lower in a target work height of a finishing shape plane than a target work height of an area plane. Next, the central processing unit 1 decides an area by synthesizing the indicated this time work area and selected area as a work object area. The central processing unit 1 removes an already worked part from the decided work object area in the selected area by a tool stored the result again in a prescribed area of an inside storage device 3 as a work object area to be displayed on a display unit 6. |
