    摘要： A method for measuring the contour of a machined part with a contour gage apparatus, having a probe assembly including a probe tip for providing a measure of linear displacement of the tip on the surface of the part. The contour gage apparatus may be moved into and out of position for measuring the part while the part is still carried on the machining apparatus. Relative positions between the part and the probe tip may be changed, and a scanning operation is performed on the machined part by sweeping the part with the probe tip, whereby data points representing linear positions of the probe tip at prescribed rotation intervals in the position changes between the part and the probe tip are recorded. The method further allows real-time adjustment of the apparatus machining the part, including real-time adjustment of the machining apparatus in response to wear of the tool that occurs during machining.

    摘要： The determination of the position of a tape thread-in and thread-out mechanism in a cassette recorder is carried out using contact paths together with a slider contact that form position switches. Output signals of the position switches are coupled via a resistor network that combines the output signals and produces an output signal on a single conductor. The resistor network output signal is coupled to an input of an analog -to-digital converter. To improve the reliability of determining the position of the mechanism without requiring the use of highly accurate resistors in the resistor network, the voltage value assigned to each individual position is measured at the output of the network during a calibration operation. The voltage values are stored in a memory and used as the desired values during normal operation.

    摘要： An improved final servo control for numerical control systems of the type which perform linear and/or circular interpolation by iterative updating of commanded position signals. The improvements are embodied in means to sense when the servo loop has had an offset error introduced by drift or aging of the final amplifier or similar components, together with means for progressively and automatically removing such error; and by means to avoid attempts at extreme acceleration or deceleration beyond the ability of the servo power element (motor) to accomplish, --by creating from an iteratively updated primary position command signal, whose rate of change may suddenly alter by a wide margin, a secondary position command signal which varies ultimately by the same amount but at a lesser rate of change.

    摘要： Method and apparatus for numerical control to produce contouring by simultaneous coordinated motions along two or more axes, characterized by the creation of desired velocity signals supplied as the primary inputs to velocity servos coupled to drive a member relatively along the respective axes. A digital computer associated with an adjustable interrupt clock which measures off successive time periods .DELTA.T, supplies a changeable velocity command number signal to each servo proportional to the distance per .DELTA.T through which motion along the associated axis is to occur. This velocity command number is algebraically added to a theoretical position number to signal dynamically during each period .DELTA.T the axis position at which the member should reside; and the latter number is used with a dynamically signaled actual position number to re-compute and signal during each period the position error. The position errors are used as a trimming or adjusting term in the signals applied to the respective axis servos.When the signaled error exceeds a first threshold on any axis, the periods .DELTA.T are lengthened to reduce all axis velocities; when it exceeds a second threshold, the system is put into a holding mode. The input signal applied to each axis servo includes a further historical adjustment term incrementally changed during any period when the error exceeds a predetermined value-- all to the objective of making the axis servos (a) operate with substantially zero following error, (b) correct themselves if the position error becomes at all appreciable, or (c) stop if that error becomes intolerable.

    摘要： The present invention relates to improvements in a method of sensing a position of a movable body by directly or indirectly converting a unit movement of the movable body into digital pulse signals and an apparatus therefor. A reference position is selected at a point, at which said movable body abuts against and presses a stopper provided at a specific position within the moving range thereof. The pulse signals are counted as the movable body moves from the stopper using the reference position as a reference number. The coincidence of the number of the pulse signals counted with a first predetermined pulse number corresponding to a predetermined position is sensed so as to sense the fact that the movable body has reached a predetermined position and position sensing signals are emitted. Further, as necessary, the position sensing signals that have been emitted are sustained for the duration of a second predetermined pulse number corresponding to a predetermined stroke preset so that the position sensing signals indicate that the movable body has reached the predetermined position and is within a predetermined stroke from the predetermined position.
