<p>PROBLEM TO BE SOLVED: To easily perform a curved surface machining desired by a designer by individually allocating the plural pieces of machining instruction information to be instructed at the time of machining a curved surface to plural operators. SOLUTION: The free-form surface selected by the designer is displayed on the display curved surface of a monitor 22 together with an end point group. The designer specifies a control point group (end point group) to be moved by using a mouse 14B and a keyboard 14C, etc., while viewing the display screen. In this case, the eight end points groups are simultaneously specified as the end point group to be moved and they are allocated to the respective dials of a dial operator 14A. By the constitution, the designer arbitrarily adds various deformation to the free-form surface by operating the respective dials of the dial operator 14A and easily performs the desired curved surface machining.</p> |
