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…

Power reactors can be heterogeneous or homogeneous. A heterogeneous power reactor has a large number of fuel rods with the coolant circulating around them and carrying away the heat released by nuclear fission. In a homogeneous reactor, the fuel and moderator are mixed…

Many hygroscopic (moisture-absorbing) materials can be used as relative-humidity sensors. Such materials absorb or lose moisture until a balance is reached with the surrounding air. A change in material moisture content causes a dimensional change, and this change can …

The common types of well-recognized hardwood and softwood timbers are Shisham, Sal, Teak, Mango, Mahogany, Kail, Chid, Babul, Fir wood, Walnut, and Haldu. Softwood includes Deodar, Chir, Kail, Fir wood, and Haldu, while hardwood includes Shisham, Sal, Teak, Mango, an…

Various functions of cutting fluids are Cutting fluid cools the workpiece and tool by carrying away the heat generated during machining. It acts as a lubricant at the friction zones, thereby increasing tool life. As friction gets reduced, the forces and electrici…

Extrusion products may be subject to considerable deformation associated with extrusion operations, and some defects can occur in these products. The defects in extruded products can be classified into three categories: Center burst Piping and Surface…
