Abstract
A laser machining device comprises a movable stage which is controlled by a stage controller. A laser produces a beam for machining and the beam is scanned over the part using a laser scanner under control of the laser scanner. The scanner controller controls the stage controller to synchronize movements of the stage with movements of the scanner. The stage may carry the part to be machined or the scanner.
Claims15
A laser machining device comprising:
- a stage controller for controlling movement of a stage;
- a laser for producing a beam;
- a laser scanner for scanning said beam over a part to be machined;
- a stage for movably holding one of a part to be machined and said laser scanner, to provide relative motion between said part to be machined and said laser scanner;
- and
- a scanner controller for controlling said scanner;
- wherein said scanner controller is configured to control said stage controller, thereby to synchronize movements of said stage with movements of said scanner.

A laser machining device comprising:
- a stage for movably holding a part to be machined;
- a stage controller for controlling movement of said stage;
- a laser for producing a beam;
- a laser scanner for scanning said beam over said part to be machined;
- a scanner controller for controlling said scanner;
- wherein said scanner controller uses a first clock at a first clock rate and said stage controller uses a second clock at a second clock rate, said second clock rate being different from said first clock rate, said stage controller being configured to use a derivative of said first clock to provide said second clock.

A laser machining device comprising:
- a stage for movably holding a part to be machined;
- a stage controller for controlling movement of said stage;
- a laser for producing a beam;
- a laser scanner for scanning said beam over said part to be machined;
- a scanner controller for controlling said scanner;
- wherein said laser scanner and said scanner controller are connected using a first frequency communication network, and said stage controller is connected using a second network with a second different frequency, said first network and said second network being connected by a bridge component, said bridge component configured to obtain a first frequency clock signal from said first network and to provide a frequency derivative of said first frequency clock signal to a master component of said second network, thereby to synchronize said first and second networks.

A laser machining device comprising:
- a stage for movably holding a part to be machined;
- a stage controller for controlling movement of said stage;
- a laser for producing a beam;
- a laser scanner for scanning said beam over said part to be machined;
- a scanner controller for controlling said scanner;
- wherein the device is configured to provide first and second derivations of a path command as control signals for said laser scanner and said stage respectively, and to compare a first delay at said scanner and a second delay at said stage, and to apply first and second fixed delays to said scanner control signal and to said stage control signal respectively to synchronize respective stage and laser beam movements.
