Water Jet Machining What is Water Jet Machining Water Jet Machining or Water Jet Cutting is a type of cutting tool widely used in many industrial applications by the usage of an extremely high-pressure jet of water onto the work piece to get the desired shape and size. Types of Water Jet Machining There are two types of water jet machining processes and are as follows. 1. Pure Water or Water Jet Machining Process 2. Abrasive Water Jet Machining Process Water Jet Machining Process: Water Jet Machining is applicable for soft materials. It acts as a cutting tool by the usage of an extremely high-pressure jet of water onto the work piece to get the desired shape and size. In this, no tool is used and the only nozzle is used to withstand higher pressures. Water is used as a medium and the wear ratio is infinity. To overcome the limitations, ...
ANEALING
Annealing is a heat treatment process that changes the physical and sometimes also the chemical properties of a material to increase ductility and reduce the hardness to make it more workable. The annealing process requires the material above its recrystallization temperature for a set amount of time before cooling. The cooling rate depends upon the types of metals being annealed. For example, ferrous metals such as steel are usually left to cool down to room temperature in still air while copper, silver and brass can either be slowly cooled in air or quickly quenched in water. The heating process cause atoms to migrate in the crystal lattice and the number of dislocations reduces, which leads to the change in ductility and hardness. The heat treated material recrystallizes as it cools. The crystal grain size and phase composition depend on the heating and cooling rates and these, in turn, determine the material properties. Hot or cold working of the pieces of metal following ann...

GEAR TRAINS
What is a Gear train? A Gear train is a combination of Gears which is used when we have to obtain large velocity reduction (or vice versa) in a limited space Gear trains are used in almost all machines which are dealing with the mechanical power. Some of the places where gear trains are used are engines , lathes , clocks, gear box and Differential of automobiles etc. Types of Gear trains Types of Gear trains Generally, there are four types of Gear trains 1. Simple Gear train 2. Compound gear train 3. Reverted gear train 4. Planetary or epicyclic gear train Let us understand each type of gear train with the help of explanation and images. Simple gear train Characteristics of simple gear train · Gears are in the form of series · Axes of gears remai...
Hydro Power Plant
Hydro Power Plant: Definition, Layout, Working Principle, Site Selection, Advantages, Application 0 Today we are going to study Definition, Layout, Working, Advantages, Disadvantages, and Application of Hydro Power Plant. Hydro Power Plant is an electricity-producing plant in which the water is an essential fuel, the potential energy is being converted into kinetic energy and kinetic energy is further converted into mechanical and into electrical energy with the help of a turbine and motor. We will understand how it works in very detail. So now let’s study construction. Hydro Power Plant Layout or Construction: The following Construction or Layout of Hydro Power Plant: Headpond or Reservoir Control gate Penstock Turbine Draft Tube Tail Race Transmission Line Generator Transformer PowerHouse Pic Credit to Sampurna Engineering Headpond: There is one reservoir which is having a large area in which A huge amount of water is being stored here. So the energy here is i...
