Answer. Reasons for importance of are nontraditional material removal processes (1) the need to shape new metal alloys and non-metals that are difficult to machine by conventional processes; (2) the requirement of unusual and complex workpart geometries; and (3)

The simplest way to describe MWD is to relate it to the measurements a pilot takes. A pilot needs to know the direction they are flying (North‚ South‚ East‚ or West)‚ the angle they are flying at (up‚ down‚ or horizontal)‚ and what type

conductivity of insulators is very low. SEMICONDUCTORS A semiconductor has electrical conductivity intermediate to that of a conductor and an insulator. Semiconductors differ from metals in their characteristic property of decreasing electrical resistivity with increasing temperature. The comprehensive theory of semiconductors relies on the principles of motion of electrons through a lattice of atoms. Current conduction in a semiconductor occurs via mobile or free electrons and holes‚ collectively

present ferrite and ferroelectric system. This may be attributed to the dipoles resulting from changes in valence states of cations and space charge polarization. The space charge polarization is governed by number of space charge carriers and resistivity of the grain boundary. The charge carriers‚ which take part in exchange‚ can be produced during sintering process [34‚35]. As the frequency increases‚ the ionic and orientational source of polarizability decreases and finally disappears due to molecular
