    摘要: A curved surface generation method well-suited for application to the preparation of a numerical control tape used in the numerically controlled machining of a three-dimensional body such as a three-dimensional mold. The surface creation method includes steps of defining, on a first section curve or reference curve of a three-dimensional curved body, a point Pi (i=1,2 . . . ) which corresponds to a point Qi (i=1,2 . . . ) on a second section curve or reference curve, and generating an intermediate section curve in accordance with the established correspondence. A curved surface is created by collecting a plurality of the intermediate section curves together. Accordingly, the invention raises the degree of freedom with which a curved surface is created, and enables the accurate creation of a curved surface featuring subtle changes, allowing the precise machining of a three-dimensional body.

    摘要: A method of creating NC data for a complex curved surface (10) which has a combination of at least two three-dimensional curved surfaces (11, 12). The NC data creation method includes inputting data specifying each of the curved surfaces (11, 12) and data for specifying cutting path patterns (a pattern 21 of radiating straight lines and a pattern 22 of parallel straight lines) for respective ones of the curved surfaces. Points are obtained discretely from a cutting starting point (P.sub.i) of one curved surface (11) to a boundary point (R.sub.i) with the other curved surface (12) along the radiating-type cutting path pattern (21) set for this curved surface. Points are also obtained discretely on the other curved surface along the cutting path pattern (22) of parallel straight lines specified with respect to the other curved surface (12). A pick-feed is performed points are obtained discretely along the cutting path pattern on each of the curved surfaces in similar fashion. NC data for generating a complex curved surface by successively traversing each of the points, is created.

    摘要: There is disclosed a numerically controlled cutting method of cutting a curved surface SF generated by interconnecting corresponding points mi, ni (i=1, 2, . . . ) on two curved lines CV1, CV2 with a cutter BT of a milling machine having simultaneously controlled five axes or a wire electrode of a wire-cut electric discharge cutting machine. According to the numerically controlled cutting method, curve information specifying the two curved lines CV1, CV2, information on tool radius or wire radius, information on the direction of tool or wire compensation, and division information for dividing the curved lines are supplied as inputs. Using the above items of information an offset position at dividing points mi, ni, which are next to dividing points mi-1, ni-1 at which the cutter BT or wire is currently positioned, is determined. The cutter BT or wire is then moved to the offset position to cut the curved surface SF.
