    Abstract: A tracing control system for tracing a groove counter can easily measure the groove contour formed on a three-dimensional model surface. A tracer head is provided with a stylus having a size enabling the stylus to slide in a groove formed on the model surface in the state that the stylus receives a load from three axial directions. Amount of displacement sensing means senses the amount of displacement of the stylus. Displacement vector calculation means calculates the displacement vector of the stylus based on the sensed amount of displacement of the stylus. Movement control means controls the positional movement of the tracer head so that the displacement vector is equal to a predetermined vector value at all times. Position sensing means senses the present position of the tracer head. Data creation means creates digitized data based on the sensed present position of the tracer head and the amount of displacement of the stylus.

    Abstract: In tracer control equipment which controls the relative feed rate between a tracer head (1) and a model by controlling a motor (12X to 12Z) according to a displacement signal (.epsilon..sub.x to .epsilon..sub.z) from the tracer head, a deceleration control circuit (18) is provided to perform deceleration control corresponding to the configuration of the model at a jerk point thereof. The deceleration control circuit (18) compares a plurality of threshold values with variation of the displacement signal (.epsilon..sub.x to .epsilon..sub.z) per unit time, and controls the relative feed rate between the tracer head and the model depending upon which region defined by the plurality of threshold values includes the amount of variation of the displacement signal.

    Abstract: Provided is a tracer control method in a master-slave type tracer system having first and second tracer units in each of which a tracer controller (TCC.sub.1, TCC.sub.2) generates velocity commands (V.sub.x, V.sub.y, V.sub.z) along respective axes by using a detection signal generated by a tracer head (TC.sub.1, TC.sub.2), motors (XM.sub.1, YM.sub.1, ZM.sub.1 ; XM.sub.2, YM.sub.2, ZM.sub.2) provided for respective axes are driven on the basis of the velocity commands and a workpiece (WK.sub.1, WK.sub.2) is subjected to tracer machining conforming to the profile of a model (MDL), tracer machining being performed by tracing a model (MDL.sub.1) with the tracer head (TC.sub.1) on the first tracer unit side and providing the second tracer unit with a move command on the basis of the tracing. In the tracer control method, the first tracer unit (TCC.sub.1, TCM.sub.1) produces the velocity commands (V.sub.x, V.sub.y, V.sub.z) in digital form to drive the motors (XM.sub.1, YM.sub.1, ZM.sub.1 ) for the respective axes, monitors a current position of a movable element, and sends a distance travelled along each axis during a predetermined time interval as a digital move command to the second tracer unit (TCC.sub.2, TCM.sub.2). A pulse distributor (PDC.sub.2) of the second tracer unit performs a pulse distribution calculation on the basis of move command data received as an input from the first tracer unit, thereby to control the motors (XM.sub.2, YM.sub.2, ZM.sub.2) of the respective axes on the side of the second tracer unit.

    Abstract: A method and apparatus for sensing the current position of a movable element in a position control system which includes first and second control devices each having a 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. The position control system also includes 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 element being sensed by one control device when the other control device is connected to the speed control circuit. The method includes steps of storing the errors which prevail in the respective storage means just prior to switching from the first control device to the second control device, returning the movable element to the position which prevailed just prior to the switching operation by supplying the speed control circuit with an offset voltage corresponding to an arithmetic difference found by subtracting the stored error from the error storage means of said second control device, from the error in the error storage means of the second control device after the switching operation when the movable element has stabilized, updating the data in a current position register of the first control device on the basis of an arithmetic difference found by subtracting the stored error from the error storage means of the first control device, from the data in the error storage means of the first control device while the motor controlled by the second control device, and revising the data in the error storage means of the first control device on the basis of the arithmetic difference.

    Abstract: An improved electronic tracing control including a tracing feed rate control circuit for modifying the tracing velocity in response to internal corners in a model. When the tracing apparatus enters an internal corner, the control circuit immediately attenuates the tracing feed rate in response to an instantaneous change in the quadrature error signal. The tracing feed rate is then gradually increased as the tracing control changes direction through the corner.
