Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum alloys
Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.
- copper alloys
Copper containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. The most common copper alloys are divided into six groups, and each group contains one of the following major alloying elements: brasses—major alloying element is zinc; phosphor bronzes—major alloying element is tin; aluminum bronzes—major alloying element is aluminum; silicon bronzes—major alloying element is silicon; copper-nickels and nickel-silvers—major alloying element is nickel; and dilute-copper or high-copper alloys, which contain small amounts of various elements such as beryllium, cadmium, chromium or iron.
Suspension of one liquid in another, such as oil in water.
- extreme pressure additives ( EP)
extreme pressure additives ( EP)
Cutting-fluid additives (chlorine, sulfur or phosphorus compounds) that chemically react with the workpiece material to minimize chipwelding. Good for high-speed machining. See cutting fluid.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
Measure of the relative efficiency with which a cutting fluid or lubricant reduces friction between surfaces.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
