A workbench is sturdy table at which manual work is done. They range from simple flat surfaces to very complex designs that may be considered tools in themselves. Workbenches vary in size from tiny jewelers benches to the huge benches used by staircase makers. Almost all workbenches are rectangular in shape, often using the surface, corners and edges as flat/square and dimension standards. Design is as varied as type of work for which the benches are used but most share these attributes: * A comfortable height for working with provisions for seated or standing work * A way to fix the workpiece to the surface so that it may be worked with both hands * Provisions for mounting, storing and accessing tools Workbenches are made from many different materials including metal, wood, stone, and composites depending on the needs of the work. ==Types== Workbench types may be divided according to the particular work they are designed to accommodate: ;Multi-purpose/portable: These benches are small, light, collapsible, and typically have built in clamps. Epitomized by the Black & Decker Workmate, a bench invented and patented by Ron Hickman,〔 (pages 211-220)〕 they can be used for a wide range of manual work. ;Woodworking: May be used for general woodworking but may be specialized for joinery, cabinetmaking, patternmaking, stairbuilding, carving, carpentry or trim work. They are usually made from solid wood and have integral clamping mechanisms. ;Metalworking: Metalworkers need benches built to handle grinding, welding, light casting and forging, and layout. Most of these benches include a metalworker's vise mounted to the top. ;Gardening: Gardener's benches must be resistant to moisture and dirt. They are used for potting, seeding, and grooming, and usually have built-in shelving and storage. ;Electronics: Formally a fixture in radio shacks, now used for assembly and repair of all sorts of electronic equipment including communication, computer, and home entertainment items. These benches usually have sources of power built in, along with shelves and task lighting. The height of most electronics benches are set for a seated worker. ;Software: Software used the metaphor of a workbench for exposing file management and application launching functionality, like in the AmigaOS workbench, or for designing processes connecting data sources to operations and models. ;General repair: Almost all family farms have one of these. Also found in small engine repair shops. Used for sharpening, cleaning, lubricating, assembly/disassembly, and light metal work. ;Laboratory work: Utilized especially with the chemical and biological sciences. Surfaces are typically made of an inert material like slate. Most of these benches have water and fuel sources built in or near at hand. ;Art and sculpture: These benches are most likely to be used in the round. They are designed so that the workpiece can be mounted firmly, usually from underneath, and accessed from all sides. Used by wood and stone carvers. ;Jewelers and Watchmakers: Purpose built benches which generally have a "bench pin" - a small wooden work surface protruding out towards the worker, allowing for working on small parts. In addition there is usually a tray or leather apron underneath to catch precious metal filings or dropped items. They are designed so that when the worker is seated the work is at or near eye level. ;Fitting and assembling: Used by machinists, pipefitters, electricians, textile workers, handloaders, and piece workers, these benches usually have space for layout and built-in tools, jigs and measuring devices to facilitate the work. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Workbench」の詳細全文を読む スポンサード リンク
