PROBLEM TO BE SOLVED: To prevent gouging from being formed and to obtain a target machined shape with high precision by evaluating two-dimensional image data according to specific standards and generating a tool movement path for machining on a base curved surface group according to the evaluation result and the tool for machining. SOLUTION: On a three-dimensional base curved surface group, two-dimensional image data are arranged and the positional relation between the base curved surface group and the two-dimensional image data is determined. Then, a lattice is formed by approximating each base curved surface with fine planes so that specified tolerance is satisfied, offset quantities of vertexes of the fine planes are found by evaluating the two-dimensional image data to offset them, and an offset process is performed according to the shape of the machining tool in use. On a lattice segment group 91 formed by connecting the offset vertexes, a tool path pattern line group is projected and a group of intersections 100 of the lattice segments and tool line patterns is connected according to tool path pattern standards to generate a machining tool movement path 101. |
