Laser control method and laser control apparatus

A laser control apparatus for controlling a laser beam irradiated, onto a target object to be processed, during execution of a laser processing program, the apparatus comprising:

• a processing condition storage section that stores previously a first processing condition table describing a plurality of different feed velocities, in association with a processing condition of the laser beam corresponding to individual feed velocities;
• a velocity detecting section for detecting an actual feed velocity which is relative processing velocity of the laser beam relative to the target object while a processing is performed along a processing path instructed by the laser processing program;
• and
• a processing condition calculating section that determines the processing condition of the laser beam corresponding to the actual feed velocity detected by the velocity detecting section based on the first processing condition table.

A laser control apparatus for controlling a laser beam irradiated, onto a target object to be processed, during execution of a laser processing program, the apparatus comprising:

• a processing condition storage section that stores previously a processing condition table describing a plurality of different corner angles, in association with a processing condition of the laser beam corresponding to individual corner angles;
• a corner angle calculating section which, while a processing is performed along a processing path instructed by the laser processing program, automatically detects a corner section included in the processing path and calculates a corner angle of the corner section;
• and
• a processing condition calculating section that determines the processing condition of the laser beam corresponding to the corner angle calculated by the corner angle calculating section based on the processing condition table.
