Field of the Invention The present invention relates to a marking method using a scanning type laser marker which scans a laser beam two-dimensionally with two galvanometers, and more particularly to a method of writing a thick line when marking a bold character. .

Description of the Related Art Conventionally, when a bold character is drawn with this type of processing machine, a bold line is drawn on a central axis 1 of the bold character while continuously giving a circular motion to a galvanometer as shown in FIG. The laser beam is moved between the starting point and the ending point, and a character having a wider line width is drawn by the trajectory 2 of the laser. Therefore, the trajectory 2 of the marking becomes a spiral. The radius of the circular motion can be specified both in software and hardware. However, as for the marking speed, the speed of the circular motion is fixed and the central axis 1 You can only specify the speed at which to move. Therefore, the pitch at which the circles overlap with each other is also determined by the speed at which the bold characters are moved on the central axis 1.

いう要求に対してマイナスである。However, in the conventional thick character marking method, the processing speed is slower at the portion outside the thick line, and spirals are closely intersected as shown in FIG. It is generally known that when performing laser processing, the processing speed is an element to be kept constant in accordance with the type of the workpiece. Experiments have also confirmed that the intersection of line segments generates burrs several times that of the case without intersection. For example, when marking was performed on the surface of the bearing, the working depth was 0 μm and the burr was 0.3 μm in the place where the lines did not overlap, whereas the working depth was 1.0 μm in the place where the lines overlapped. And the burr became 3.0 μm. In recent laser marking, there is a high demand that the line width is large and burrs due to processing are small.
Having a large number of intersecting line segments within a bold line is a minus for the requirement of reducing burrs.
