  • METHOD FOR PRESSING TAILSTOCK OF MACHINING APPARATUS, MACHINING APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
    Publication number: 20230302543
    Abstract: A machining apparatus includes a processor configured to control an actuator to move a tailstock in a first direction at a first speed, to detect a contact between the tailstock and a workpiece based on a change in an input amount to the actuator while the actuator is controlled to move the tailstock at the first speed, to control the actuator to stop moving the tailstock when the contact is detected, to control the actuator to move the tailstock by a first distance in a second direction, to control the actuator to move the tailstock in the first direction at a second speed lower than the first speed, and to control the actuator to stop moving the tailstock, when the input amount to the actuator becomes a value corresponding to the target pressing force while the actuator is controlled to move the tailstock at the second speed.
