A way of feeding the die in a stamping press. with raw material.
AISI stands for the American Iron and Steel Institute, and is a four-digit identification number used to specify different types of carbon steel coils. The first two digits indicate the grade of steel, and the last two give the amount of carbon that the steel contains.
A narrow ridge of metal used to strengthen a flat sheet metal workpiece or part.
Computer Aided Design. Software to design parts. Examples are AutoCAD, Solidworks, SolidEdge etc.
Customer Asset Management.
Computer Numeric Control. Refers to the computer integrated into a machine (such as a mill, router, laser etc) to receive and process instructions.
A narrow ridge of metal used to strengthen a flange of a part. The dart is formed into the edge of the flange and the part.
Wire electrical discharge machining (EDM). It uses a wire electrode that travels through the workpiece. Wire EDM removes metal with electricity by means of spark erosion.
Enterprise Resource Planning. As MRP, but including additional features such as data warehousing, accounts, human resources etc.
The process of coating steel with zinc, which creates a surface that is highly resistant to corrosion.
A measurement of thickness. Standard gauges include the Galvanized Sheet Gauge (GSG), United States Standard Gauge (USS) and Birmingham Wire Gauge (BWG).
Gas Tungsten Arc Welding.
Inside Diameter. Used to measure the width of a coil or tube.
Japanese for "improvement" or "change for the best", refers to philosophy or practices that focus upon continuous improvement of processes in manufacturing, engineering, business management or any process.
A cutting process where material is sliced or cut without producing a slug or separating the workpiece.
The use of a highly concentrated beam of light to generate enough heat to pierce and cut, using CO2 and fibre optic lasers.
Materials Resources Planning or Material Requirement Planning. Factory management/planning software, allowing companies to control and plan production, stock, purchasing, dispatch etc.
The punching of multiple holes, often identical and arranged in a regular pattern, in a sheet, blank, or formed part. The holes are often round, but could be of any shape.
The process of forming an phosphate coating on metal by immersion in an aqueous phosphate solution.
Product Lifecycle Management.
Plane of bend. The orientation of a bend in relation to the axis of the straight section preceding it. Used specifically for changes of plane in successive bends.
The traveling plate onto which one part of a stamping die is mounted in a press. Also referred to as the slide.
A long V-shaped or radiused indentation. It is used to strengthen large sheet metal panels.
The reddish material that form on iron or its alloys resulting from exposure to water/humidity or chemical attack. It mainly consists of hydrated iron oxide.
Material handling machine located at the beginning of a process which is used to hold and safely deliver or uncoil the steel strip.
The resistance of a fluid to flow or motion within itself.
Joining two pieces of material by applying heat, pressure, or both. Sometimes this will be with or without a filler material. The join is produced through fusion/recrystallisation across the interface.
