摘要:
This machine tool has a first rotating feed shaft around a first axis line that is inclined with respect to all the linear motion axes of the machine coordinates. Table coordinates are set ahead of time in the machine tool. The table coordinates have an imaginary first linear motion axis, an imaginary second linear motion axis, and an imaginary third linear motion axis that are perpendicular to each other, and an imaginary first rotating feed axis around an imaginary first axis line. The imaginary third linear motion axis is parallel to a third linear motion shaft extending in the direction of the axial line of a main spindle. One imaginary linear motion axis of the imaginary first linear motion axis or the imaginary second linear motion axis is set above the surface of a workpiece attachment surface, and the imaginary first axis line is set parallel to the one imaginary linear motion axis. A computation unit computes the coordinate values of the imaginary first rotating feed axis in the table coordinates, and a display unit displays the coordinate values of the imaginary first rotating feed axis.

By an actuator control method and an actuator control device that perform "energy evaluation control" that compares kinetic energy of a controlled object and work that can be done by braking and switches driving to braking at a point of time at which the kinetic energy of the controlled object and the work that can be done by braking become equal, and also repeatedly makes a comparison between the kinetic energy of the controlled object and the work that can be done by braking at each preset time, as a new control method that replaces PID control in mechanics for effectively utilizing vehicle energy to improve vehicle fuel consumption and control methods thereof, a control result is obtained by a simpler method.

A stop range setting circuit (1) sets a stop range of a control object on the basis of a target position signal, and a PBR (6) detects a present position of the control object driven by a motor (5). The comparison circuit (2) compares the present position of the control object with the set stop range, and outputs an out-of-stop range signal (e) and a rotating direction indication signal (f) until the control object reaches the stop range. The out-of-stop range signal (e) is input to a drive start determination circuit (3), and a drive permission signal (g) is output to a drive circuit (4) when the out-of-stop range signal (e) is continuously output for at least a predetermined period of time. The drive circuit (4) drives the motor (5) in a direction indicated by the rotating direction indication signal (f) while the drive permission signal (g) is continuously output, so that an instantaneous ON/OFF signal is not input to the drive circuit (4) in the presence of external noise.
