摘要： A machine tool includes a time calculation unit calculating the time for a spindle to arrive at a target rotational speed, and the time for a spindle head to arrive at a target position; a comparison unit comparing the time to arrive at the target rotational speed and the time to arrive at the target position; and a drive control unit controlling the drive of the spindle and the drive of the spindle head. The drive control unit controls the drive of the spindle head, when a determination is made that the time to arrive at the target rotational speed is longer than the time to arrive at the target position, such that the time for the spindle head to arrive at the target position is longer than the calculated time to arrive at the target position, and less than or equal to the calculated time to arrive at the target rotational speed. Accordingly, the machine tool can drive the spindle head that is a control object in a power-saving mode.

摘要： A feed apparatus has a ball screw, a nut, a drive motor, a braking mechanism and a controller and moves a movable body vertically. When recognizing a movement command for rapid traverse relating to the movable body, the controller, when the movable body is to be moved upward, moves the movable body past a target position according to the movement command and then reverses the moving direction thereof and moves the movable body to the target position and stops it there, and, when the movable body is to be moved downward, moves the movable body directly to the target position and stops it there. After moving the movable body to the target position and stopping it there, the controller causes the drive motor to keep the position of the movable body at the stop position and causes the braking mechanism to brake the movement of the movable body.

摘要： Relative movement in X, Y and Z axis directions is made between a main spindle and a table 6 for application in a machine tool in which a work is machined. An emitting element 12 for irradiating laser beam 11 and a photosensitive element 13 are disposed on the table 6. A measuring tool 8 with its top end being shaped as a cone form is attached to the main spindle 4. The laser beam 11 is interrupted with the cone form portion 15 of the measuring tool 8 through relative movement between the table 6 and measuring tool 8 before and after machining a work. Detection signal of interruption is generated at the moment of interruption, position is detected, operation processing is performed so that difference in X, Y and Z axes before and after machining is obtained along with values for correction. Positional coordinate values for three axis directions are detected simultaneously with a measuring device of a simple constitution by use of laser beam and values for correction such as of thermal displacement is obtained by operation processing of displacement values.

摘要： The invention concerns a feed system control method and apparatus that can calculate an accurate backlash amount and can accomplish highly precise position control. Position errors are calculated before and after a reversal in direction of movement of a slide 30, each from the difference between the position data of the slide 30 detected by a linear scale 25 and the position data of the slide 30 calculated from the rotational position data of the servo motor 23 detected by a rotary encoder 24. The backlash amount of the slide 30 is calculated from the difference between the position error before the reversal and the position error after the reversal thus calculated. Thereafter, when reversing the direction of movement of the slide 30, the feed speed during direction reversal is increased in accordance with the backlash amount.
