A unit vector calculating unit of a laser machining device obtains a unit vector based on respective current rotational positions of an A-axis and a B-axis. A movement command calculating unit, a speed command calculating unit, or a torque command calculating unit generates a command signal for maintaining a gap amount at a constant value, based on the unit vector, and the gap amount between a machining nozzle and a workpiece. With a servo control unit, on the basis of the command signal, an X-axis motor, a Y-axis motor, and a Z-axis motor are controlled, whereby the machining nozzle is moved relatively in three-dimensional directions with respect to the workpiece.

A method for predicting and compensating frictions of a feed system includes following steps: constantly obtaining current signals and angle-position signals of a motor by a motor driver of a feed system after being activated; calculating frictions of the motor upon each rotating position according to the obtained current signals and angle-position signals and generating multiple records of friction data; creating a friction model according to the multiple records of friction data and the angle-position signals each respectively corresponding to each record of friction data with respect to each rotating position; importing current angle-position signal of the motor to the friction model for predicting a predicted friction; calculating a compensation current based on the predicted friction; and, controlling the motor driver to additionally provide the compensation current to the motor for conquering an upcoming friction of the feed system approximate to the predicted friction.

An electric motor-driven screwdriver includes a control circuit having a memory stored with setting data and a computing unit controlling the electric motor-driven screwdriver based on the setting data. The computing unit sets an execution order of work processes based on a pre-designated piece of order setting data, and sets, based on a next operation setting value, a next operation to be performed after completion of the final work process. The next operation setting value is selectable from among a setting value for stopping the operation of the electric motor-driven screwdriver, a setting value for repeating a series of work processes, and a setting value for shifting to a series of work processes in an execution order determined based on another piece of order setting data.

A method for controlling a filling process, wherein a predetermined filling quantity of a medium is filled into a container, the flow rate of the medium flowing into the container is measured as a time series of measured values for the instantaneous flow rate and a filling quantity already filled is estimated from the time series, wherein at least one current measured value of the time series is corrected on the basis of at least one earlier measured value of an earlier time series of measured values of the flow rate of an earlier filling process.
