A method of forming sheet metal by using heated dies of metal or ceramic.
Industry:Aviation
A method of forming sheet metal parts by using a soft-faced hammer to shrink or stretch the metal. The metal may be formed over forming blocks or dies, or it may be shaped by hammering it into a sandbag.
Industry:Aviation
A method of forming sheet metal. A disk of metal is clamped in a lathe in front of a male die whose shape is that of the inside of the part to be spun. The lathe is turned at a high speed, and the metal is forced against the die with a wooden tool.
Industry:Aviation
A method of forming threads on a bolt or rod by rolling the material to be threaded between grooved rollers. No material is removed when the threads are rolled, as it is when they are cut.
Industry:Aviation
A method of grounding an electrical circuit by connecting all of the wires that go to ground to a single point on the equipment chassis. When single-point grounding is used, there is very little current flow in the chassis, and the interference from magnetic fields in the chassis is avoided.
Industry:Aviation
A method of guidance used on some missiles that causes the missile to seek and home on a source of infrared radiation.
Industry:Aviation
A method of hardening and strengthening metal that cannot be hardened by heat treatment. When the metal is hammered, rolled, bent, or stretched, it becomes work hardened.
Industry:Aviation
A method of hardening metals that cannot be hardened by heat treatment. Copper, some aluminum alloys, and low-carbon steel cannot be hardened by heat treatment, but they can be hammered, rolled, pulled, or bent to change their grain structure enough that they become hard.
Industry:Aviation
A method of hardening steel by heating it red-hot and then quenching it in a bath of oil. Oil cools the steel more slowly than either water or brine and gives it a uniform hardness.
Industry:Aviation
A method of heat transfer by direct contact in which heat energy moves from a higher energy level to a lower level by direct contact. A hand touching a hot stove will be burned because heat energy from the stove is transferred by conduction.
