    摘要： A method of generating data defining a tool path for a numerically controlled machine (14) is designed for generating machining tool path data without establishing offset plane data, so that the machining tool path depth data can be established for discontinuous, surfaced, offset planes which might otherwise cause interference in the tool path. The method includes the steps of forming a plurality of patches defining a three-dimensional plane to be machined, sub-dividing each patch into a predetermined number of segments as divided by a plurality of grid points so that the distance is maintained to be smaller than the machining area of the machine tool (14). The machining depth at each grid point within the tool path is derived with respect to the maximum height position at which the machining tool comes into contact with the grid point. The machining depth is modified with a correction value which is determined in terms of the surface condition of the surface to be machined.

    摘要： A method of generating a complex curved surface (CPS) consisting of at least two three-dimensional curved sufaces (10a, 10b), and more particularly to a method of generating a complex curved surface in which the intersecting portion of the first and second curved surface is rounded. In this method of generating a complex curved surface, the normal vectors V 1 , V 2 to the first and second curved surfaces (10a,10b) at the intersecting point P o of first and second sectional curved lines (11, 12), which is obtained when the first and second curved surfaces (10a, 10b) are cut with a sectional plane (13) normal to an XY-plane, are determined, and an angle θ made by V 1 X V 2 and the normal vector V of the sectional plane (13) is then computed. When the rounding with a radius R is given, R' is computed in accordance with the equation, R'= (1+1/ Icosθ1). R/2, and the rounding is made by inserting an arc having the radius R' into the intersecting portion. The R' represents an average value of a major axis (=R/Icosθ1) and a mirror axis (=R) of an ellipse.
