    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.

    摘要: A cut contour display method in a wire electric discharge machine for subjecting a workpiece to taper cutting by moving a workpiece relative to a wire electrode and moving a wire tensioning guide horizontally has a first step of entering a programmed path (WDP) lying on the lower surface of the workpiece, workpiece thickness, data including a taper angle or a vector indicating a positional offset between the upper and lower surfaces of the workpiece, and data specifying a number of cross-sectional contours. A second step includes obtaining a wire electrode path (WUP) on the upper surface of the workpiece, which is not a programmed surface, by using the programmed path (WDP), workpiece thickness, and the taper angle or vector indicative of the positional offset. A third step includes obtaining coordinate values of points on each cross-sectional contour at an end portion of each block by using data indicative of the wire electrode paths on the upper and lower surfaces of the workpiece and the number n of cross sections. A fourth step includes displaying, on a display unit, the wire electrode paths on the upper and lower surfaces of the workpiece, as well as each cross-sectional contour of the taper-cut surface, by using the data indicative of the wire electrode paths on the upper and lower surfaces of the workpiece and coordinate values of the points on each cross-sectional contour at the end portion of each block.

    摘要: A linear interpolating method used for controlling the movement of a robot in which a speed distribution at the time of linear movement of a multi-articular robot involves a linear acceleration and deceleration so that precision of movement is improved at a driving start point and an end point of the robot. Linear acceleration and deceleration are realized by a discrete time state equation so that a sampling time is reduced and the precision of a straight line is improved while making high speed movement possible. The method computes a positional deviation on the basis of the present position and a target position and then exact driving is maintained via compensating for positional deviation.

    摘要: A cylindrical interpolation system for machining a cylindrical surface of a cylindrical workpiece, wherein a tool diameter correcting means (104) obtains a tool center path by calculating a tool diameter offset vector for a machining shape specified with reference to an assumed orthogonal coordinate system, and an interpolating means (107) interpolates the tool center path and outputs an interpolation pulse (PCyi) related to an assumed linear axis and an interpolation pulse (PZi) related to a cylindrical axis. To effect a reverse conversion from the assumed orthogonal coordinate system to the cylindrical coordinate system, a pulse converting means (108) converts the interpolation pulse (PCyi) into an interpolation pulse (PCi) for rotating the rotary axis. A block-start correction component calculating means (105) and synchronous correction component calculating means (109) calculate correction components (Vcy, .DELTA.Vcy), and these correction components (Vcy, .DELTA.Vcy) are interpolated by a block-start correction component interpolating means (106) and synchronous correction component interpolating means (110), and added to the interpolation pulse (PCi) for rotating the rotary axis. As a result, the tool cutting surface can be always located immediately above the axis of rotation of the workpiece, and the side surface being machined is at a right angle to the cylindrical surface of the workpiece.
