摘要:
This invention finds application in the machining of stones and the like, and relates to a method for forming surface markings particularly on slabs of hard material or the like, and to an apparatus for carrying out such method. The method comprises the steps of providing a plurality of tools (8) for forming surface markings that are aligned with predetermined center-to-center distances (i), translating the tools (8) parallel to the lying plane (π) to form a first succession of aligned and equally spaced markings (A), feeding the product (P) being machined relative to the tools (8) to form another succession (B) of aligned and equally spaced markings, different from the first succession (A), repeating the previous steps to cover the whole longitudinal extension of the surface (S) of the product (P). The successions of markings are either arranged in offset and non overlapping positions, or in at least partly overlapped positions according to a predetermined pattern.
