も問題が大きい。Conventional technology and its problems Conventionally, laser processing of new ceramics has been known, but it has been limited to cutting and drilling, and has not yet reached the level of cutting. Laser processing is, in principle, a processing method that melts or erodes the workpiece by projecting a laser spot of high-density light energy onto the workpiece, but it is not possible to directly apply this to cutting the workpiece. Can not. In fact, cutting of new ceramics currently relies on the method using a diamond cutting tool. Neuceramic is extremely difficult to process due to its material and mechanical properties, and cutting with a diamond cutting tool is still inefficient, and since diamond cutting tools are expensive, there is a big problem in terms of cost.

加工を工業的に確立し得るのである。Effects of the Invention In the present invention, concave grooves extending in the X-axis direction or Y-axis direction are formed on the processed surface of news ceramic by projecting a laser spot so that the grooves are distributed in small parallel pitches. By this processing, the part to be processed of the news ceramic is turned into a thin protrusion from the original surface, and therefore, after or while making the concave marks, the thin protrusion part is made from the side of this. This can be easily cut by projecting a laser spot along the protrusion.
That is, according to the present invention, the surface to be processed of the new ceramic is laser processed in the X-axis direction or Y-axis direction and in a direction from the side of the direction, and the combined result of processing in both directions is Therefore, the projection of a laser spot, which does not have surface cutting ability due to the processing principle, can contribute to surface cutting. Thus, according to the present invention, the workpiece is moved in a desired direction relative to the projection of the laser spot by a suitable means, for example, a feeding means such as in a machine tool, and the new ceramic is cut by laser processing. Processing can be established industrially.

よる加工より経済的である。 In addition, since the processing method of the present invention is laser processing, high-speed processing is possible regardless of whether it is a two-way composite processing, and the efficiency is almost twice as high as that of conventional cutting processing using a diamond cutting tool. However, it is also preferable from an economic point of view. Laser processing equipment is not a consumable item like a diamond tool, but
It has semi-permanent durability, and after a certain period of time, laser processing is more economical than processing with a diamond tool.

率的である。 If the construction method according to the present invention is a method in which the concave grooves are formed on the processed surface of the news ceramic by laser processing, and then the protrusions based on the grooves are cut by laser processing, one A laser head can be used for these processes, and therefore, the necessary processes such as surface scraping or flattening are economical in terms of equipment, and while making the concave groove marks, it is possible to cut the protrusions. In this method, the required processing is efficient because the grooves are made and the protrusions are cut at the same time.
