DC Machine - Construction, Working, Types,

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

Drilling - Wikipedia

Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point.The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is
