摘要： A cutting method in which a workpiece is cut on the basis of a plurality of tool paths parallel to one another into a shape having a corner that protrudes outward. A machining step for machining the workpiece on the basis of one tool path and a moving step for moving to the starting point of the next machining step after the completion of the one machining step are repeated. In the machining step, a cutting step for cutting the workpiece in the one tool path and a removing step for removing a burr by moving a tool relatively to the workpiece in the same tool path as that of the cutting step in a region forming the corner are successively performed.

摘要： In an actuator control method and an actuator control device, time optimal control is used, and a switching time at which an acceleration output is switched to a deceleration output, and an end time of the deceleration output are calculated using a maximum acceleration and a maximum deceleration at the time of a maximum output of a control force. A control force of an actuator is set as a maximum acceleration output from a calculation time to the switching time, the control force of the actuator is set as a maximum deceleration output from the switching time to the end time, output of the control force is ended at the end time, and the switching time and the end time are repeatedly calculated, and updated for each preset time. The control output is reduced along with decrease of residual energy, which is a sum of remaining work and kinetic energy of a control system. From this, an element of feedback control is incorporated in the time optimal control, and the control output is converged after the end of the control.

摘要： A motor control device includes a power converter, a velocity controller, and a certain-position stop controller. The power converter outputs a driving current on the basis of an input torque command. The velocity controller generates a calculated torque command on the basis of a difference between a velocity represented by a velocity command and a motor velocity. The certain-position stop controller performs position control by, after first detecting a reference position of a motor during velocity control, generating a position command for positioning the motor from the reference position to a target stop position at a torque of a torque schedule, generating the velocity command on the basis of a difference between a position represented by the position command and the motor position, and outputting a value resulting from adding a torque feedforward command generated on the basis of the torque schedule to the calculated torque command.

摘要： A motor control apparatus includes a motor that rotates a controlled object, an encoder that outputs a pulse signal in synchronization with a rotation of the motor, and a control section that performs a feedback control so as to rotate the motor to the target rotational position. The control section includes a stopping and holding control portion. The stopping and holding control portion performs a stopping and holding process in which the stopping and holding control portion supplies electric current to the motor so as to stop and hold the motor for a current-supply holding time. The stopping and holding control portion sets the current-supply holding time on the basis of a rotation speed of the motor just before the stopping and holding process.

摘要： An encoder includes: a main scale having two or more band-shaped tracks in each of which an optical main grating is formed so that longitudinal direction of the main scale corresponds to a measurement axis direction; and an index scale opposed to the main scale so as to form a diffraction interference optical system in cooperation with the main grating, disposed so as to be movable relative to the main scale in the measurement axis direction, and in which two or more optical index gratings are formed. A plurality of slits included in the main grating in at least one track are formed so as to be inclined at a predetermined inclination angle from a direction perpendicular to the measurement axis direction so that pitch of the slits in the track becomes equal to the pitch of the slits in the at least one other track.

摘要： The invention relates to a method and a device for guiding the movement of a moving machine element on a numerically controlled machine, whereby maximum possible track speed, maximum possible track acceleration, and maximum possible track jerk are defined by means of given restrictions on track axes. The local minima for the maximum possible track speed are determined, whereby for each local minimum a corresponding left-sided and right-sided track speed segment is determined, whereby, for track values for the displacement track to the left and right of a given minimum, the resulting track speed is determined by using the maximum possible track jerk and the maximum possible track acceleration until the track speed exceeds the maximum possible track speed to the left and right of the minimum, a track jerk curve for the movement guidance is hence determined. According to the invention, a simple method and a simple device for movement guidance of a moving machine element on a numerically controlled machine are achieved, with as good as possible a usage of the restrictions on machine axes of the machine.

摘要： There is provided a digital controller which can reduce a variation in output voltage as compared to the conventional digital controller at the time of abrupt changes in load and in input of a power amplifier. The digital controller is built in the power amplifier for supplying an output voltage vo to a load and is equipped with a manipulated variable calculating unit which detects the output voltage vo to calculate a manipulated variable ξ1 and a signal generating unit which converts the manipulated variable ξ1 into a signal for making the power amplifier operate. A feedforward function from an equivalent disturbance qy caused by the variation in the load is replaced by a feedback function from the output voltage vo and the manipulated variable ξ1, thereby allowing a transfer characteristic from the disturbance qy to the output voltage vo to result in a quadratic differential characteristic. Consequently, the variation in output voltage can be reduced as compared to the conventional controller at the time of the abrupt changes in the load and in the input of the power amplifier.

摘要： An integrated motor and position sensor achieves motion between a moving portion and a stationary portion by electrically energizing poles to interact with magnetics respectively on the moving and stationary portions. The position sensor includes a plurality of sensing coils placed to intercept the magnetic flux between a plurality of the poles and the magnetics. The outputs from these coils are fed to a microprocessor DSP through an internal or external A/D converter. The microprocessor or DSP decodes the measured voltages using resolver strategies to produce a position, velocity or acceleration measurement.
