The advantages and benefits of selecting die casting over sand casting (Sand Molded Casting) are listed below. The die casting process requires less floor space in comparison to the sand casting process. Die-casting helps provide precision dimensional control, resulti…

There are several operations related to drilling. Some of them are: Reaming, Tapping, Counterboring, Countersinking, Center drilling, and Spot facing These are illustrated in Figure 1 and described in this section. Most operations follow…

The advantages of liquid fuels over solid fuels are as follows: Requirement of less space for storage Higher calorific value Easy handling and transportation Better control of consumption by using valves and number of burners Absence of danger from spontaneous combust…

Iron and Steel's microconstituents are Austenite, Ferrite, Cementide, Pearlite, Bainite, Martenite, Troostite, Sorbite, and Ledeburite. Austenite (γ-iron):  It is a solid solution of ferrite iron carbide in gamma iron, which is formed when steel contains carbon u…

The excellent properties of water as a moderator and coolant make the P ressurized Water Reactor (PWR) a natural choice for power reactors. The most important limitation of a pressurized water reactor (PWR) is the critical temperature of the water, which is 374°C. Thi…

The die casting process is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured surface metal parts. It is accomplished by injecting liquid metal at a fast velocity and under high pressure into reusable steel dies. Die cast…

The deburring operation is performed by the deburring tool to remove burrs. Burrs are thin ridges, usually triangular in shape, and are typically an unwanted piece of material that develops along the edges of a workpiece during operations such as machining, shearing s…
