A processing method for a surface of a workpiece using a rotating cutting tool, includes a processing method for forming a cut pattern by rotationally cutting a surface of a workpiece using a rotating cutting tool having cutting edges extending in a rotation axis direction at a plurality of circumferentially separated positions on an outer circumference of a body thereof. Each of the cutting edges includes a plurality of segmental edges segmented at an equal pitch in the rotation axis direction. A ratio of depth d to width W (d/W) of a knife mark formed on the surface of the workpiece by the segmental edges is not less than 3/100.

A flexible structure is formed by subjecting cellulose-based natural wood material to a chemical treatment that partially removes hemicellulose and lignin therefrom. The treated wood has a unique 3-D porous structure with numerous channels, excellent biodegradability and biocompatibility, and improved flexibility as compared to the natural wood. By further modifying the treated wood, the structure can be adapted to particular applications. For example, nanoparticles, nanowires, carbon nanotubes, or any other coating or material can be added to the treated wood to form a hybrid structure. In some embodiments, open lumina within the structure can be at least partially filled with a non-wood substance, such as a flexible polymer, or with entangled cellulose nanofibers. The unique architecture and superior properties of the flexible wood allow for its use in various applications, such as, but not limited to, structural materials, solar thermal devices, flexible electronics, tissue engineering, thermal management, and energy storage.

A method of fabricating a wooden perch which is affordable, has a reduced chance of infection or infestation, and provides increased comfort for animals. The method of fabricating a wooden perch generally includes the steps of providing a piece of wood and using a wood crafting assembly to create natural, randomized contours along the exterior of the piece of wood to complete the wooden perch. The piece of wood is rotated along its length across a wood crafting assembly in two opposite directions to create an interwoven sine-wave pattern along its length. Random parts of the wood are then applied to the wood crafting assembly at random angles with random pressure levels to create a natural contour along the length of the perch. Mounting hardware may be included to aid in securing the perch to various surfaces, such as an indoor bird cage or an outdoor bird feeder.

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.

Clamp for limiting cracks in logs, having two blades which each extend from a back surface to a cutting edge along a cutting direction and which are tapered in the cutting direction, the cutting directions of the two blades are aligned parallel to one another and wherein the two blades are connected by a first connecting bar which extends between first end regions of the two blades and by a second connecting bar which extends between second end regions of the two blades.

A system having a conveyor assembly, at least one scorching assembly, and a central controller. The conveyor assembly has a conveyor that effects movement of at least one board or panel relative to a movement axis. Each scorching assembly has a combustion chamber, at least one burner, and at least one processing unit. Each burner can be mounted to the combustion chamber and at least partially received within the combustion chamber. Each burner can be oriented toward the conveyor. The at least one processing unit can be communicatively coupled to the at least one burner and configured to selectively control activation and operation of the at least one burner. The central controller can be communicatively coupled to each processing unit of the at least one scorching assembly and configured to receive a user input corresponding to a scorching profile for the at least one board or panel.
