    摘要： A non-contact tracer control device for carrying out a profile machining on a workpiece while tracing the profile of a model in a non-contact fashion. Two non-contact distance detectors (5a, 5b) are slantingly mounted to a tracer head 4) controlled through a rotary axis, and measurement values obtained by the two non-contact distance detectors (5a, 5b) are sampled at predetermined sampling intervals. Based on the measurement values obtained at previous and current sampling times, coordinates of the four vertexes of a very small rectangle on the surface of a model (6) are obtained, and a normal vector is obtained by using the coordinates of three required vertexes out of the four vertexes. The tracer head (4) is rotated in the direction of a projected vector obtained by projecting the normal vector onto an X-Y plane. Accordingly, the measurement axes of the non-contact detectors (5a, 5b) are oriented in a direction as perpendicular as possible to the model surface, thus permitting a high-accuracy distance measurement.

    摘要： A tracing control system for machining a workpiece through tracing by calculating speed commands of respective axes, using change amounts detected by a tracer head, and by moving a cutter relative to the workpiece through a control of the speed of the respective axes in accordance with the speed commands. First delay speed commands are obtained from the speed commands (Vx, Vz) at delay circuits (14a, 14c), respectively, and second delay speed commands are obtained at second delay circuits (14b, 14d), respectively, the differences between the first delay speed commands and the above second delay speed commands are calculated, and an X-axis main motor and a Z-axis main motor are driven in accordance with the first delay speed commands, and an X-axis sub-motor and a Z-axis sub-motor are driven in accordance with the calculated differences, thereby move the tracer head. As a result, the tracer head always precedes the cutter, and when the tracer head comes to a corner and the axis speed is reduced, the precedence amount of the tracer head is canceled out (relatively returned) by the amount corresponding to the speed reduction. This return amount can be made equal to the amount of over-run of the tracer head, and therefore, the amount of movement of the cutter is reduced by this over-run amount of the tracer head, to thereby prevent overshot machining.

    摘要： An arbitrary-direction tracer control system moves a model and a tracer head relative to each other at an arbitrary angle to a reference axis X along lines passing through a reference point K, first and second tracing stroke limits L1 and L2 are set at which tracing feed is returned, so that tracing feed is along radial lines a - b, c - d, e - f and f - g extending from the reference ponts K, and pick feed operations are carried out by predetermined amounts b - c and f - g at the tracing stroke limits L1 and L2. As a result, tracing feed can always be performed in a direction perpendicular to a curved surface of the model, ensuring accurate tracing of the curved surface.

    摘要： The invention relates to a pick-feed method in rotating body tracing for performing tracer control by rotating a model (MDL), advancing or retracting a stylus (ST) in contact with the model, in dependence upon the shape of the model, in a direction of the center of rotation (O.sub.M), and pick-feeding the stylus in a plane parallel to a rotational axis of the model every revolution of the model. This pick-feed method includes forming first and second areas (AI, AII) by dividing the full circumference of the model in half by a straight line (LL') connecting a point (P.sub.L) having a predetermined rotational angle (.theta..sub.L) and the center of rotation (O.sub.M) of the model, determining in which area the stylus (ST) is present when the stylus is rotated relative to the the model (MDL) by rotating body tracer control, refraining from executing a pick-feed when the stylus enters the second area (AII) from the first area (AI), and executing a pick-feed when the stylus enters the first area from the second area.

    摘要： A method of sensing the current position of a movable element in a position control system which includes first and second control devices each having command pulse generating means and error storage means for computing and storing an error between a number of command pulses and a number of feedback pulses indicative of an amount of motor movement, a speed control circuit for driving and controlling the motor on the basis of the error in the storage means, and a switching circuit for selectively connecting the first and second control devices to the speed control circuit, the current position of the movable elements being sensed by the first control device when the second control device is connected to the speed control circuit. The method includes the following steps, when the second control device is connected to the speed control circuit, of reading and storing, as a steady deviation, the error in the error storage means of the first control device after the motor is rotated in accordance with the magnitude of drift of a closed loop formed by the second control device. The data in a current position register of the first control device is then updated on the basis of an arithmetic difference found by subtracting the stored steady deviation from the data in the error storage means of the first control device and revised in the error storage means of the first control device on the basis of the arithmetic difference.
