Determination method and determination program to determine the processing range and processing the order at the time of forming the hole or notch that spans more than one surface to the material

摘要

PROBLEM TO BE SOLVED: To provide a determination method which automatically determines a processing range and a processing order for processing surfaces respectively, for forming a hole or a notch across multiple surfaces in a material by using a laser processing device.SOLUTION: Development figure data is prepared by setting an outer surface corner part of a material as a development auxiliary line, and a range corresponding to board thickness of the material as a pair of board thickness lines interposing the development auxiliary line, and by setting a processing range of a hole or a notch to be formed in the material. In the step S1, the processing range is divided into a plurality of blocks by using the development auxiliary line and the board thickness lines, and when there exists a block positioned at a surface area excluding a board thickness area and if the block is combined with a block that is positioned at a neighboring board thickness area while interposing the development auxiliary line, the block is determined to be processable. In the step S2, the plurality of blocks are grouped into a plurality of processing groups, and when block height of a processing start surface is equal to or greater than a preset aperture minimum height, the block is determined to be processable.
