1.3 WORKING PRINCIPLE OF MILLING MACHINE Working of a milling machine is based on the fact that milling cutter is fed against workpiece. This is achieved by developing relative motion with precise control between workpiece and rotating milling cutter. Feed motion is generally given to the workpiece through its holding device.

Horizontal-Axis Wind Turbine Working Principle. The horizontal-axis wind turbine (HAWT) is a wind turbine in which the main rotor shaft is pointed in the direction of the wind to extract power. The principal components of a basic HAWT are shown in Figure 1. The rotor receives energy from the wind and produces a torque on a low-speed shaft.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. Wind is a form of solar energy caused by a combination of three concurrent events:

The specific working principle is as follows: After the alternating current is rectified by the diode, the direction is single, but the current is still changing constantly. This pulsating DC is generally not directly used for radio power supply. Therefore, it is necessary to convert the pulsating DC into a smooth wave DC, which is filtering.
