    摘要： Uses a generic sensor to provide a rotary encoder with high accuracy, excellent environmental resistance, and low cost that is equivalent to having a precision sensor. A generic type rotary encoder comprising a generic sensor, a rotation angle detector that outputs information on the rotation angle of the rotary shaft of the motor based on an output signal from the generic sensor, and an encoder control unit, wherein the encoder control unit comprises a function for driving an initial setting motor, an initial setting data acquisition function for acquiring initial setting data unique to the generic sensor, a normal operation data acquisition function that acquires and generates data for normal operation used when the motor to be controlled to which the generic type rotary encoder is mounted is normally operated, and an EEPROM recorded calibration data to calibrate the initial setting data unique to the generic sensor, wherein the calibration data is obtained, by using a standard sensor that guarantees high accuracy of 2 digits or 3 digits higher than the generic sensor, and by simultaneously connecting the generic sensor and the standard sensor to the initial setting motor and driving the initial setting motor at least one forward and reverse rotation, and the calibration data is data for calibration relating to the rotation angle of the rotary shaft.

    摘要： A control system for operation of an industrial machine includes a processor and a tangible, non-transitory, computer-readable memory communicating with the processor. The tangible, non-transitory computer-readable memory includes instructions that, in response to execution by the processor, cause the processor to perform operations including: receiving image data from an imaging device that monitors an image zone around the industrial machine, and analyzing the image data. The processor further performs operations including determining, based upon the analyzing, that the control system is functional, determining, based upon the analyzing, that the image data includes at least one of a predefined color, a predefined pattern, and a predefined shape, and transmitting a proximity signal to at least one relay module coupled between the processor and the industrial machine to halt operation of the industrial machine.

    摘要： The present disclosure is directed toward a system that includes a first optical sensor, a second optical sensor, and a gear feature controller. The first optical sensor measures a plurality of first distances measured from a first reference point to a surface provided between a pair of adjacent teeth among a plurality of teeth circumferentially distributed about a first side of a gear. The second optical sensor measures a plurality of second distances measured from a second reference point to a surface along a second side of the gear opposite the first side. The gear feature controller configured to determine a stock removal amount of the gear based on the first distances and the second distances.

    摘要： A machine tool having a rotatable machine tool spindle for performing drilling and tapping operations. The spindle has limited axial movement relative to the spindle carrier. Fluid pressure means may be operated to displace the spindle in opposite directions for a predetermined position in the spindle carrier and to apply a force yieldably opposing return of the spindle to the predetermined position. The position of the spindle in its carrier is sensed by control means and the spindle carrier is translatable toward or away from the workpiece in response to the direction of displacement of the spindle from its predetermined position. The spindle is displaced forwardly to effect translation of the spindle carrier and spindle to engage a tool with a workpiece and the return of the spindle to the predetermined position upon the engagement of the tool with the workpiece is utilized to initiate control means for automatically controlling the depth of drilling or tapping as measured from the surface of the workpiece and the return of the spindle to an automatic repeat position or to a home position. The spindle is allowed to float while a tapping tool is in engagement with the workpiece and the feed and return of the spindle carrier is controlled during this period by sensing the position of the spindle in the carrier. During drilling the spindle is locked against axial movement relative to the carrier while the tool is in engagement with the workpiece. The locking means is engageable over the range of axial movement of the spindle relative to the carrier to locate the spindle in a predetermined position relative to the carrier.
