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. ## Claims ### Claim 1 A surface texturing apparatus, comprising: an actuated tool holder including: a first actuator including a rotating disk having a first face, a second face, and an edge; a cutting tool mounted to the first face of the rotating disk at a radial distance from a center of the rotating disk, the radial distance defining a predetermined effective radius of the actuated tool holder; a second actuator; and a guide for positioning an article in relation to the surface texturing apparatus such that a surface of the article facing the cutting tool is at a predetermined mean distance from or overlap with the cutting tool, the first actuator is configured to draw the cutting tool across the surface of the article facing the cutting tool along an arcuate path having the predetermined effective radius, carving a groove into the surface of the article facing the cutting tool which replicates a circular saw milling mark of a circular saw blade having the predetermined effective radius; the surface of the article facing the cutting tool also faces the first face of the rotating disk; the second actuator is configured to modulate a distance between or overlap of the cutting tool and the surface of the article facing the cutting tool, and as the article is advanced along the surface texturing apparatus, the surface texturing apparatus is configured to carve a plurality of replicated circular saw milling marks into the surface of the article facing the cutting tool, replicating a circular saw milled texture in the surface of the article facing the cutting tool. ### Claim 2 (depends on 1) The surface texturing apparatus of claim 1, wherein the second actuator is arranged and disposed to modulate the distance between or overlap of the cutting tool and the surface of the article facing the cutting tool between or during the carving of each groove into the surface of the article, effecting a pseudo-random modulation of the circular saw milled texture. ### Claim 3 (depends on 1) The surface texturing apparatus of claim 1, wherein the second actuator actuates the actuated tool holder or the cutting tool. ### Claim 4 (depends on 1) The surface texturing apparatus of claim 1, wherein the second actuator actuates the guide for positioning the article. ### Claim 5 (depends on 1) The surface texturing apparatus of claim 1, wherein the at least two independent actuators include a third actuator which advances the article along the surface texturing apparatus. ### Claim 6 (depends on 5) The surface texturing apparatus of claim 5, wherein the third actuator is arranged and disposed to vary a speed at which the article advances along the surface texturing apparatus while replicating the circular saw milled texture, effecting a pseudo-random modulation of the circular saw milled texture. ### Claim 7 (depends on 1) The surface texturing apparatus of claim 1, wherein the cutting tool is selected from the group consisting of chip breakers, circular saw bits, chisel edges, stylus points, angled planer blades, and combinations thereof. ### Claim 8 (depends on 1) The surface texturing apparatus of claim 1, wherein the second actuator induces rotational wobble in the rotating disk, and the rotational wobble translates the cutting tool toward and away from the surface of the article facing the cutting tool. ### Claim 9 (depends on 8) The surface texturing apparatus of claim 8, wherein the second actuator is selected from the group consisting of an air jet, a water jet, an electromagnet, an adjustable guide, a hydraulic, pneumatic, or electromagnetic rod, a hydraulic, pneumatic, or electromagnetic block, or a hydraulic, pneumatic, or electromagnetic hammer, and combinations thereof. ### Claim 10 (depends on 8) The surface texturing apparatus of claim 8, wherein the rotational wobble is a regular oscillation. ### Claim 11 (depends on 8) The surface texturing apparatus of claim 8, wherein the rotational wobble is an irregular oscillation. ### Claim 12 (depends on 1) The surface texturing apparatus of claim 1, further including a guide block adjacent to the rotating disk which is arranged and disposed to limit rotational wobble of the rotating disk. ### Claim 13 (depends on 1) The surface texturing apparatus of claim 1, wherein the second actuator axially translates the rotating disk toward and away from the surface of the article facing the cutting tool. ### Claim 14 (depends on 1) The surface texturing apparatus of claim 1, further including at least one additional cutting tool mounted to the rotating disk at about the radial distance from the center of the rotating disk and circumferentially displaced from the cutting tool around the rotating disk.
