PROBLEM TO BE SOLVED: To take in even the curve surface definition expression of a different type, to integrate it into one curve surface expression and to execute the curve surface work of a desirable shape with a speedy operation by defining plural curve surfaces with the plural definition expressions as bases by means of algebraic method or an analysis method by an integration expression.;SOLUTION: A CPU 24 inputs a curve surface and a curve line by other CAD data and CAM data and discriminates a relation showing the curve surface and the curve line. Namely, it is discriminated whether all inputted curve surfaces and curve lines are shown by a rational expression and a solution is obtained by an algebraic method or whether at least one curve surface and one curve line are not shown by the rational expression and the solution is obtained by an analysis method. When all the curve surfaces and curve lines are shown by the rational expression, the solution is obtained by using the algebraic method. When the curve surface and curve line without the rational expression are contained, the solution is obtained by using the analysis method. The obtained solution is defined by an integration expression, an intersection point and an intersection line are calculated, the central travel point of a tool is obtained and NC data is generated.;COPYRIGHT: (C)2000,JPO
