Abstract
A wire electrical discharge machine includes: a supporting member for relatively moving a wire electrode relative to a measurement target; servomotors for moving the supporting member; a setting changer for changing the setting of a directive speed; and a motor controller that controls the servomotors in performing move-and-contact detection for detecting contact between the wire electrode and the measurement target by moving the two relative to each other, so that the wire electrode is moved relative to the measurement target based on the directive speed changed and specified by the setting changer.
Claims10
A wire electrical discharge machine for positioning a wire electrode supported by upper and lower wire guides or measuring a shape of a measurement target, by moving the wire electrode and the measurement target relatively to each other to detect contact, comprising:
- a driver configured to relatively move the wire electrode to the measurement target;
- servomotors configured to move the driver;
- a setting changer configured to change a setting of a directive speed;
- and,
- a motor controller configured to control the servomotors in performing move-and-contact detection for detecting contact between the wire electrode and the measurement target by moving the wire electrode and the measurement target relative to each other, so that the wire electrode is moved relative to the measurement target based on the directive speed changed and specified by the setting changer.
A measuring method for use in a wire electrical discharge machine that includes:
- a driver configured to move a wire electrode supported by upper and lower wire guides relative to a measurement target;
- servomotors configured to move the driver;
- and a contact detector configured to detect contact between the wire electrode and the measurement target, to position the wire electrode or to measure a shape of the measurement target, by moving the wire electrode and the measurement target relatively to each other to detect contact, comprising:
- a setting change step of changing a setting of a directive speed;
- and,
- a motor control step of controlling the servomotors, in performing move-and-contact detection for detecting contact between the wire electrode and the measurement target by relatively moving the two relative to each other, so that the wire electrode is moved relative to the measurement target based on the directive speed changed and specified in the setting change step.
