    摘要: A digitizing control apparatus successively receives positional data and produces NC data while tracing the shape of a model. The digitizing control apparatus has a tracer head (3) having first and second non-contact-type distance detectors (30a, 30b) for independently measuring distances up to the surface of the model, the first and second non-contact-type distance detectors being positioned to travel parallel to a feed direction. A sampling circuit (16) samples measured values from the first and second distance detectors (30a, 30b) at predetermined times. A memory (13) stores a previously sampled measured value from the non-contact-type distance detector (30a) and a previously sampled measured value from the non-contact-type distance detector (30b). Data in a normal direction of the model surface (4) are determined based on at least three of the previously sampled measured values, a presently sampled measured value from the non-contact-type distance detector (30a), and a presently sampled measured value from the non-contact-type distance detector (30b). Therefore, the data in the normal direction can be obtained at high speed. The data in the normal direction thus determined are used in the determination of a tool offset, for example.

    摘要: 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.

    摘要: 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.

    摘要: A non-contact tracing control apparatus is disclosed which traces the surface of a model by using at least two optical distance detectors for detecting the distances therefrom to the model. When a first light corresponding to a first of the optical distance detectors is detecting a distance, a second light of another, second optical distance detector is either dimmed or shut off. Interference between more than one light reflected from the model and errors from, i.e., the first light reflected from the model incident on a second position sensor of the second optical distance detector can be avoided. The distances to a plurality of measurement points thus can be detected without interference even though the measurement points on the surface of the model are relatively close to one another.
