Method for pressing tailstock of machining apparatus, machining apparatus, and computer-readable storage medium

A method for pressing a tailstock of a machining apparatus, the method comprising:

• setting a target pressing force that an actuator is to apply via the tailstock to a workpiece attached to a spindle in a first direction along a rotation axis of the spindle;
• controlling the actuator to move the tailstock in the first direction at a first speed;
• detecting a contact between the tailstock and the 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;
• controlling the actuator to stop moving the tailstock upon detection of the contact;
• controlling the actuator to move the tailstock by a first distance in a second direction opposite to the first direction along the rotation axis;
• controlling the actuator to move the tailstock in the first direction at a second speed lower than the first speed;
• and
• controlling 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.

A non-transitory computer-readable storage medium storing a computer program for causing a processor to execute a process comprising:

• obtaining a target pressing force that an actuator is to apply via a tailstock to a workpiece attached to a spindle in a first direction along a rotation axis of the spindle;
• controlling an actuator to move the tailstock in the first direction at a first speed;
• detecting a contact between the tailstock and the 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;
• controlling the actuator to stop moving the tailstock upon detection of the contact;
• controlling the actuator to move the tailstock by a first distance in a second direction opposite to the first direction along the rotation axis;
• controlling the actuator to move the tailstock in the first direction at a second speed lower than the first speed;
• and
• controlling 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.
