Abstract
A three-dimensional laser machine includes a machine head, a controller for positioning the machine head and controlling an orientation of a nozzle, and a sensor for detecting a distance between a workpiece and the nozzle. The controller is capable of performing a profile control of correcting the position of the machine head based on the detected distance. When the machine head has reached a predetermined position part way through an approach process of moving the machine head from an approach start position to a machining start position while controlling the pose of the nozzle, the controller performs the profile control to move the machine head to the machining start position.
Claims8
A three-dimensional laser machine, comprising:
- a machine head having a nozzle, the nozzle through which a laser beam is guided and emitted to a workpiece;
- a controller connected to at least one motor, the at least one motor used by the controller to position the machine head and control an orientation of the nozzle;
- and
- a sensor included on the machine head, the sensor detects a distance between the workpiece and the nozzle, the detected distance being provided to the controller, wherein
- the controller performs a profile control of correcting a position of the machine head based on the detected distance,
- when the machine head reaches a predetermined first position part way through an approach process of moving the machine head from an approach start position to a machining start position while controlling the orientation of the nozzle, the controller performs the profile control and moves the machine head to the machining start position, and
- the controller executes a control program for moving the machine head from the approach start position to a predetermined second position along a route connecting the approach start position and the second position, the first position is on the route.
A method for controlling a three-dimensional laser machine, the method comprising:
- causing a machine head of the three-dimensional laser machine to approach, via at least one motor, from an approach start position to a machining start position while controlling, via the at least one motor, an orientation of a nozzle of the machine head;
- detecting, via a sensor included on the machine head, a distance between the workpiece and the nozzle;
- performing, when the machine head has reached a predetermined first position part way through approaching the machining start position, a profile control of correcting a position of the machine head based on the detected distance between the workpiece and the nozzle;
- and
- executing a control program for moving the machine head from the approach start position to a predetermined second position along a route connecting the approach start position and the second position, the first position is on the route.
