Indexing: Meaning and Methods | Milling | Industries | Metallurgy
The operation of rotating the job through a required angle between two successive cuts is termed as indexing. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. It helps to divide the job periphery into a number of equal divisions, i.e., square, hexagonal octagonal, etc.

Working Principle of Ammeter | Complete Guide (2023)
Working Principle of Ammeter: The working principle of an ammeter depends on the current flowing along with its resistance. Very little impedance is used inside the ammeter as it must drop the least amount of voltage attached to it. The ammeter is connected to the series of circuits as the current in the series circuit is the same.

How a Wind Turbine Works | Department of Energy
When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag.

How Do Wind Turbines Work? | Department of Energy
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

CNC Milling
This milling operation lets us create chamfers, grooves, etc. There are several ways to accomplish these features. In the case of a regular 3-axis mill, the use of different cutters makes the most sense. These can be dovetail cutters to produce angled grooves or just a mill with a conical cutting head for chamfering.
