Abstract
The laser machining apparatus of the present invention is configured to analyze and adjust a cutting order of opening forming regions in order to prevent a scrap rising from interfering with a laser head by determining a first opening forming region and a second opening forming region based on interfering conditions of the scrap rising with the laser head and processing the second opening forming region prior to the processing of the first opening forming region.
Claims7
A laser machining apparatus comprising:
- a machining apparatus main body including a table on which a plurality of skids are arranged, and configured to irradiate a material mounted on the skids with a laser beam from a laser head and cut the material;
- and
- a control device configured to control the machining apparatus main body to cut around an opening forming region set in the material and form an opening, wherein
- the control device:
- determines that the opening forming region where a scrap rising after processing is to be formed in a plurality of scraps formed by cutting around the opening forming region is a first opening forming region,
- determines, in a case where the first opening forming region is processed and the scrap rises, whether or not the opening forming region is an opening forming region where the scrap rising reaches and interferes with the laser head and adds a predetermined interference width to an outer circumference of the opening forming region where the scrap rising is determined to interfere with the laser head, and
- determines that the opening forming region where the laser head is moved to a position at which the laser head interferes with the scrap rising is a second opening forming region, and
- controls the machining apparatus main body to perform processing in such a processing order that the second opening forming region is processed prior to the processing of the first opening forming region.
A laser machining method in a laser machining apparatus including a table on which a plurality of skids are arranged, and configured to irradiate a material mounted on the skids with a laser beam from a laser head and cut the material, the laser machining method comprising:
- determining that an opening forming region where a scrap rising after processing is to be formed in a plurality of scraps formed by cutting around the opening forming region set in the material is a first opening forming region;
- determining whether or not the opening forming region is an opening forming region where the scrap rising reaches and interferes with the laser head and adding a predetermined interference width to an outer circumference of the opening forming region where the scrap rising is determined to interfere with the laser head;
- determining, in a case where the first opening forming region is processed and the scrap rises, that the opening forming region where the laser head is moved to a position at which the laser head interferes with the scrap rising is a second opening forming region;
- in a case where the scrap of the opening forming region interfering with the interference width added region is determined not to rise, adopting such a processing order that the second opening forming region is processed prior to the processing of the first opening forming region;
- and
- in a case where the scrap of the opening forming region interfering with the interference width added region is determined to rise, forming a joint in the opening forming region.
