  • Patent number: 11305445
    Abstract: A surface texturing apparatus is disclosed comprising an actuated tool holder, at least two independent actuators, a cutting tool, and a guide for positioning an article in relation to the apparatus. A method of replicating a circular saw milled texture in the surface of the article is further disclosed. A first actuator draws the cutting tool across the surface of the article along an arcuate path having a predetermined effective radius, carving a groove into the surface of the article which replicates a circular saw milling mark of a circular saw blade having the predetermined effective radius. A second actuator modulates distance between or overlap of the cutting tool and the surface. As the article is advanced along the surface texturing apparatus, a plurality of replicated circular saw milling marks are carved into the surface of the article, replicating the circular saw milled texture.
