摘要： This invention relates to a method of creating a complex curved surface, which includes a step of from data specifying three-dimensional curved surfaces (12a, 12b). Data is input specifying a reference line of intersection (CL.sub.i) on the XY plane (10) and a rule for generating lines of intersection on the XY plane on the basis of the above-mentioned reference line of intersection. Also a range (SCR1, SCR2) is specified for each of the three-dimensional curved surfaces (12a, 12b) to obtain a section curve on the three-dimensional curved surface, for a section corresponding to one of the lines of intersection. The method includes obtaining first and second section curves (13a', 13b') in the range (SCR 1, SCR2) when first and second three-dimensional curved surfaces (12a, 12b) are cut by a section whose line of intersection with the XY plane is an i-th line of intersection (CL.sub.i). Then, a point of intersection (CR.sub.i) between the two section curves (13a', 13b') is obtained. Thereby, a set of first and second section curve segments A1 - CR.sub.i, CR.sub.i - B2), having the point of intersection (CR.sub.i) as a boundary, are used to define a section curve of the complex curved surface (11). The complex curved surface (11) is generated from sets of these section curves.

摘要： A method for generating data defining a tool path for a numerically controlled machine 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, subdividing each patch into a predetermined number of segments as divided by a plurality of dividing points, with the number of segments being variable depending upon the distance between adjacent dividing points so that the distance is maintained to be smaller than the machining area of a machine tool. The machining depth at each dividing point within the tool path is derived with respect to the maximum height position at which the machining tool comes into contact with the dividing 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： The method involves entering section data relating to two sections (11, 12) of a three-dimensional curved body, data relating to first and second section curves (11a, 12a) formed by the two sections (11, 12), and data relating to a three-dimensional curve (31a) which contains points (P.sub.1, P.sub.1 ') on the first and second section curves, and which specifies the external shape of the three-dimensional curved body. An intermediate section (41) is generated for each and every one of partition points (S.sub.i) (i=1, 2, 3 . . . ) that partition the three-dimensional curve (31a) into a multiplicity of line elements, the intermediate section containing the respective partition point. An intermediate section curve (41a) in the intermediate section is calculated by using the data relating to the two section curves (11a, 12a) and position information indicative of the partition points (S.sub.i), and a curved surface of a three-dimensional curved body is created by the intermediate section curves.
