Laser processing control method

A system for controlling a laser processing apparatus, said laser processing apparatus comprising laser means for machining a workpiece using a laser beam and movement means for moving said laser beam relative to said workpiece, the system comprising data processing means for executing in parallel computer readable and computer executable instructions in a laser control module and a movement control module, said laser control module having instructions comprising:

• a) determining a plurality of laser action locations where at least one laser action for said laser means is supposed to occur and determining what at least one laser action is supposed to occur at each one of said plurality of laser action locations
• b) determining a current position of said laser beam relative to said workpiece
• c) comparing said current position with at least one of said plurality of laser action locations determined in step a)
• d) in the event a difference between said current position and said at least one laser action locations is within a predetermined acceptable range, based on determinations in step a), executing said at least one laser action for said corresponding laser action location through said laser means
• e) repeating steps b)-d) for each laser action location and each laser action determined in step a)
• said movement control module having instructions comprising:
• f) determining a sequence of a plurality of movement action locations where motion change actions are supposed to occur
• g) sequentially controlling said movement means to position said laser beam relative to said workpiece at each one of said plurality of movement action locations
• wherein said laser control module and said movement control module continuously exchange data to execute steps a)-g).
