A method for shaping a carrier sheet of high hardness, in particular a gres sheet, the method comprising the steps of: - providing a solid carrier sheet of high hardness having a thickness of at least 6 mm; - covering a front surface of the carrier sheet with a removable vibration-absorbing protective layer; - providing (S 110) the surface of the protective layer remote from the carrier sheet with a glass sheet; - on the back surface of the carrier sheet opposite the front surface thereof, forming a plurality of cavities according to a predetermined pattern, the step of forming comprising: - forming the cavities by milling so that in each cavity the remaining thickness of the carrier sheet along the front surface is at least 3 mm and at most 5 mm; - during milling, at least one physical property of the vibration of the carrier sheet is continuously measured on the front surface of the carrier sheet by means of at least one sensor; - on the basis of at the least one physical property measured by the sensor, adjusting the operation of the milling tool so that the vibration properties of the carrier sheet do not exceed predetermined threshold values; - by applying a first optical method, taking a first 3D image of the surface roughness of the milled cavities; - further reducing the surface roughness of the cavities by shot blasting, wherein during the shot blasting, the operation of the shot blasting tool is controlled using parameters determined on the basis of the first 3D image taken during the first scanning; - by applying a second 3D scanning, taking a second 3D image of the surface roughness of the cavities treated by shot blasting; and - by applying laser beam milling, further reducing the surface roughness of the cavities, wherein the operation of the laser beam milling tool is controlled on the basis of the second 3D image taken after the laser beam milling by the second 3D scanning so that the surface roughness of the cavities falls in the submicron range. - providing a solid carrier sheet of high hardness having a thickness of at least 6 mm;
