Employer. David Wilkinson & Company. Known for. invented a lathe for cutting screw threads. David Wilkinson (January 5, 1771 – February 3, 1852) [1] was a U.S. mechanical engineer who invented a lathe for cutting screw threads, which was extremely important in the development of the machine tool industry in the early 19th century.
A rotary lathe in which the wood is turned against a very sharp blade and peeled off in one continuous or semi-continuous roll. Rotary-cut veneer is mainly used for plywood, as the appearance is not desirable because the veneer is cut concentric to the growth rings. A slicing machine in which the flitch or piece of log is raised and lowered ...
Barrel man (novelty) A barrel man or barrelman is a souvenir doll or statuette popular in the Philippines. The statuette usually consists of a crude male figurine carved out of wood, partially hidden inside a round wooden barrel. When the barrel is taken off, the male figure inside is revealed, sporting a prominent phallus in the lower part of ...
Multiaxis machining. A 5-axis water jet cutter and a part manufactured with it. Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting.
Gun drills (through coolant drill) are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill's hollow body to the cutting face. They are used for deep hole drilling —a depth-to-diameter ratio of 300:1 or more is possible. Gun barrels are the obvious example; hence the name.
Newer Blades: 18 to 22 inches (46 to 56cm) Blade type. Single-edge Blade. Hilt type. Ivory, Carabao horn or Kamagong. Scabbard / sheath. Wood. The barong is a thick, leaf-shaped, single-edged blade sword. It is a weapon used by Muslim Filipino ethnolinguistic groups like the Tausug, Sama-Bajau, or Yakan in the Southern Philippines.
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits. The term single-point diamond turning (SPDT) is sometimes applied, although ...
Cutting tool (machining) In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation. The majority of these tools are designed exclusively for metals.
