- High-tensile material is adopted as a material for achieving both.
- Body parts using high-tensile materials have very high rigidity compared to conventional parts using mild steel materials, making it difficult to cut and drill holes using conventional press methods. Therefore, a part using a high tensile material may be subjected to cutting or drilling with a laser beam instead of a press method.
- Processing with laser light is performed by a three-dimensional laser processing machine (for example, Patent Document 1 and Patent Document 2).
- Laser processing is to cut or punch a workpiece by irradiating a workpiece of a workpiece, which is a workpiece, with laser light to melt the member and blowing the molten member with gas or the like.
- the three-dimensional laser processing machine includes a condensing lens in order to improve the processing accuracy of laser processing and irradiates laser light through the condensing lens.

Therefore, a portion melted by the laser beam is reduced, and a fine shape, a small range of cutting and drilling can be performed, and thus high-precision processing can be performed.
- the irradiation area of the laser beam on the workpiece affects the processing accuracy of laser processing.
- As an element for determining the irradiation area of the laser beam there is a distance between a focal position where the laser beam is focused and a work portion of the workpiece. Therefore, it is important to grasp the distance and set it to be a predetermined distance during laser processing.

- the gap sensor measures the distance (gap) of the workpiece to the workpiece, calculates the distance between the focal position of the laser beam to be irradiated and the workpiece workpiece from the gap measurement value, and the calculation result is the machining setting in laser machining. Check if it is within the tolerance of the value.
- the laser beam is irradiated from the laser beam irradiation unit to perform cutting or drilling.
