摘要： An apparatus and method for distressing material, such as a board. The apparatus may include a cutter head supporting a blade, a guide member, and a flattening device. The flattening device and the guide member are positioned proximate the cutter head and on opposite sides thereof. In response to the cutter head and the surface of the material being brought into cutting contact and moved relative to each other, a resulting portion of the surface of the material is distressed. The flattening device maintains the proper vertical position of the cutter head and blade relative to the material and a material support as the material is being brought into cutting contact with the cutter head. The guide member levels warped material boards thereby bringing the board into proper elevation and engagement with the blade for cutting or scraping a top surface of the board. The material may be wood.

摘要： A system and related methods are disclosed for distressing a workpiece, which may be a building surfacing material. The system may include a material support defining a material support plane for supporting the workpiece and a distressing apparatus mounted adjacent the material support. The distressing apparatus includes a cutting blade and is configured to translate the blade back-and-forth along an impact axis between: (1) an extended or projected state in which the blade edge is a first distance from the material support plane; and (2) a retracted state in which the blade edge is a second distance from the material support plane greater than the first distance. A drive subsystem generates relative movement between the workpiece and distressing apparatus. A controller repetitively reciprocates the blade back-and forth to repetitively impact the workpiece, thereby forming a chatter mark on the workpiece surface comprised of substantially parallel seriatim angled grooves or cuts.

摘要： A method of distressing a board is disclosed. In one embodiment, the method comprises: a) supporting the board on a material support, the board having a substantially planar surface; b) providing a blade having a front surface and a curved back cutting surface, the front surface and the curved back cutting surface intersecting to form a curved tip; c) directing the blade and the substantially planar surface into cutting contact; and d) generating relative movement between the blade and the board to distress a portion of the substantially planar surface; and wherein during step d), the blade is maintained in a fixed orientation relative to the substantially planar surface of the board so that an obtuse mount angle is maintained.
