ABSTRACT

Computer Aided (or Assisted) Machining (or Manufacture).

(1) A exible electrical insulated conductor or group of conductors twisted (usually multistranded) together for the transmission of electrical energy. (2) Rope or chain, particularly in marine contexts.

Cadmium (symbol Cd) is a silvery-white crystalline metal that has a specic gravity of 8.6, is very ductile, and can be rolled or beaten into thin sheets. It resembles tin and gives the same characteristic cry when bent, but is harder than tin. A small addition of zinc makes it very brittle. It melts at 320°C and boils at 765°C. Cadmium is employed as an alloying element in soft solders and in fusible alloys, for hardening copper, as a white corrosion-resistant plating metal, and in its compounds for pigments and chemicals. It is also used for Ni-Cd batteries and to shield against neutrons in atomic equipment, but gamma rays are emitted when the neutrons are absorbed, and these rays require an additional shielding of lead.
