Laser processing system and method

A laser processing method, wherein laser processing is performed on a processing target using a processing machine according to a processing design, the method comprising:

• (a) preparing, according to predetermined setting criteria, a processing recipe comprising a plurality of set values for testing of processing parameters for controlling a quality value of a predetermined quality item;
• wherein the plurality of set values comprises one of power, frequency, pulse width, duty ratio or focal length of a laser beam,
• (b) repeatedly performing first test processing for the processing target in multiple implementation rounds by driving the processing machine by selectively using any one of the set values for testing as a set value of the processing parameters according to a predetermined order;
• (c) analyzing each of results of the first test processing and individually measuring a quality value of each of the results of the first test processing;
• and
• (d) selecting, among the set values for testing, a set value for testing used in a specific implementation round of the first test processing, at which a quality value that most satisfies predetermined reference quality is measured, as a set value for manufacturing a product from the processing target of the processing parameters, wherein the manufacturing is controlled based on the set value for manufacturing the product;
• wherein the processing design is provided to have a processing shape corresponding to a shape of the product, and
• wherein the processing shape is defined by a pattern to be processed, which comprises at least one of a line and a dot,
• in step (a), the pattern to be processed includes a plurality of sections each having different shapes, the pattern to be processed is divided into a plurality of processing units each including one of the plurality of sections and the processing recipe for each of the processing units is individually prepared;
• and
• in step (b), first test processing for each of the processing units is individually performed, wherein, first test processing for a specific processing unit among the processing units is performed by selectively using one of the set values for testing in the processing recipe for the specific processing unit based on a shape of a corresponding section of the specific processing unit.
