    摘要: A curved surface machining method for machining a curved surface through unidirectional cutting by automatically creating a pick-feed path that will not cause a tool (TL) to strike a workpiece when a pick-feed is performed, pick-feeding the tool along the path, and thereafter performing cutting. The pick-feed path is obtained by using a given tool retraction quantity l for retracting the tool from a cutting path end point Pe, a clearance plane (CPL), coordinate values of the cutting end point Pe, and coordinate values of a cutting starting point Ps on the next cutting path. Specifically, there are obtained: coordinate values of a point Pa distanced from the cutting path end point Pe by the tool retraction quantity l in the direction of the central axis of the tool; coordinate values of the foot Pb of a perpendicular dropped from the point Pa to the clearance plane (CPL); coordinate values of a point Pd distanced from the cutting starting point Ps of the next cutting path (PT2) by the tool retraction quantity l in the direction of the central axis of the tool; and coordinate values of the foot Pc of a perpendicular dropped from the point Pd to the clearance plane. The path Pe.fwdarw.Pa.fwdarw.Pb.fwdarw.Pc.fwdarw.Pd.fwdarw.Ps serves as the pick-feed path.

    摘要: A method of machining performed by back-and-forth cutting, particularly a machining method for automatically creating a pick-feed path that will not cause a tool (TL) to interfere with a workpiece (WK) when a pick-feed is performed, moving the tool along the pick-feed path, and thereafter performing cutting. If the workpiece is concave in the proximity of the pick-feed path, the method includes obtaining an approach plane (AP) containing a machining end point (Pe) and lying parallel to a plane (PL) which contacts a curve (OLC) of the external shape of the workpiece at a next machining starting point Ps. Then a point of intersection Pc between the approach plane (AP) and a straight line (SL) passing through the machining starting point Ps is obtained, with the straight line coinciding with the direction of the central axis of the tool at the machining starting point. The path Pe.fwdarw.Pc.fwdarw.Ps serves as the pick-feed path. If the workpiece is convex in the proximity of the pick-feed path, the method includes obtaining the approach plane (AP) contacting the curve (OLC) of the external shape of the workpiece at the next machining starting point Ps. Then the point of intersection Pc between the approach plane (AP) and a straight line (SL') passing through the machining end point Pe is obtained, with straight line coinciding with the direction of the central axis of the tool at the machining end point. The path Pe.fwdarw.Pc.fwdarw.Ps serves as the pick-feed path.

    摘要: The present invention relates to a tool radius compensation method for numerically controlled apparatus in which the coordinates Pi of the position of a tool center are computed which is offset a distance equal to the radius r of the tool in a direction normal to a surface to be cut based on commanded positional information P.sub.1, Pc and P.sub.2, for enabling the tool to three-dimensionally cut a workpiece. Based on the positional information P.sub.1, Pc and P.sub.2, a unit offset vector Vi is determined which lies on a plane defined by vectors U and V normal to first and second surfaces to be cut at a three-dimensional corner point Pc. Components along respective axes of the unit offset vector Vi are corrected so that the tool center will move smoothly along a curve contiguous to paths of movement of the tool center before and after the three-dimensional corner point Pc. The coordinates Pi of the position of the tool center are determined from the corrected unit offset vector Vi', a tool radius r, and the information Pc on the position of the three-dimensional corner point.
