    摘要： A method of forming data of a composite curved surface maintaining high precision and quickly. After a part program is input, there are input via a keyboard reference curves (BC11, BC12, BC21, BC22) that specify first and second curved surfaces (SS1, SS2) which form a composite curved surface (SS) and data that represent operation curves (DC11, DC12, DC21, DC22). Then, a processor (102) divides by cut pitches (b1, b2) the operation curves and an intermediate sectional curve (M) that is obtained by dividing the reference curves related to the curved surfaces by cut pitches (a1, a2) designated in the part program. The processor then calculates coordinate positions (PT'(x, y, z)) at four apexes of each of many quadrilateral tiny planes (PT) constituting the curved surface that is obtained, and stores the calculated results, i.e., mesh data representing the curves in the memory. Thus, there is formed a composite curved surface consisting of two mesh data.

    摘要： This invention relates to an NC data preparation method for simultaneous 5-axis control and comprises the steps of determining a point (Ai) on a curve forming the locus (Mk) of the tip of a tool in a three-dimensional curve surface (SS), determining a normal vector (N(Boolean not)) and a tangential vector (T(Boolean not)) of the tool tip locus at this point (Ai), determining next the outer product vector (S(Boolean not)) of the normal vector (N(Boolean not)) and the tangential vector (T(Boolean not)), determining the tool center axis vector (V(Boolean not)) using the direction inclined a designated angle toward the direction of the product vector (S(Boolean not)) form the normal vector (N(Boolean not)) on the plane (PL) formed by the normal vector (N(Boolean not)) and the product vector (S(Boolean not)) as the direction of the tool center axis and preparing the NC data for the simultaneous 5-axis control by use of the coordinates values of the point (Ai) and the tool center axis vector (V(Boolean not)).
