    摘要： An apparatus and method for measuring the electrical load on a motor driven tool operating in a cycle having idle and cutting or machining states. The electrical power is continuously measured and an average power value is established during the idle state of at least one cycle and used as an offset subtracted from the measured electrical power values to generate an output proportional to the incremental power drawn by the cutting tool during the cutting state. The offset value is recalculated at the start of each new cycle and/or just prior to the commencement of a cutting operation by a tool. At least one filter and/or an amplifier are used to improve the signal-to-noise ratio of the output signal.

    摘要： An active sensor calibration system includes a plurality of sensors configured to measure at least one physical quantity. Each sensor is configured to output a signal indicating at least one measured physical quantity. An electronic scenario library module is configured to store a plurality of scenarios. Each scenario is configured to excite two or more selected sensors among the plurality of sensors to generate redundancy among the selected sensors based on physical quantity models. An electronic calibration module is in signal communication with the plurality of sensors and the scenario library. The calibration module is configured to select at least one scenario from the scenario library module, determine at least one possible un-calibrated sensor among the plurality of sensors, and to identify a positive un-calibrated sensor in response to executing the at least one selected scenario.

    摘要： Four basic measurements are performed when calibrating a spherical measurement probe fastened to a tool spindle having a fixed longitudinal position along the spindle axis. Moving the measurement probe transversely towards the calibration sphere yields a basic position of the tool spindle relative to an element with an attached calibration sphere, when measurement probe touches the calibration sphere. The measurement probe is rotated about the spindle axis from one basic measurement to the next by the same angle, whereas the orientation of the calibration sphere is maintained for all four basic measurements. Based on the basic positions, a reference position of the tool spindle relative to the element, at which the tool spindle is located above the calibration sphere and the spindle axis goes through a central point of the calibration sphere, is determined and taken into account in further calibration of the measurement probe.

    摘要： A robot includes: an arm driven by a motor; an angle sensor that detects a pivoting angle of the motor; an inertia sensor that detects an inertial force acting on the arm; a noise detecting unit that detects a noise frequency of the inertia sensor from both an output of the angle sensor and an output of the inertia sensor; a filter-constant determining unit that determines a characteristic of a filter from information of the noise detecting unit; and the filter that removes noise of the inertia sensor on the basis of the filter-constant determining unit.

    摘要： An actuator having a two-parameters energy converter is coupled to a transducer and is driven by a controller. Prior to assembly and operation of the actuator, a calibration procedure is performed. The calibration procedure, together with the unique controller, enable accurate control of the output parameters of the actuator. In one example, the parameters are rate and force, and the calibration and controller enable accurate control of the rate and force at the output of the actuator by measuring only the rate at the output of the energy converter. Consequently, no sensors are needed at the output of the actuator, i.e., at the output of the transducer, where the load is applied.
