Manufacturing Processes:
Importance of Manufacturing: The importance of manufacturing is that a gives usable product from the ore of different metals and from different material which cannot be used in their present condition.
2.Economic Definition : Manufacturing increase the value of product.
3.Technological Definition : Manufacturing is a process which gives required strength, shape and size of the product.
4.Survey of Manufacturing : A usable product is manufactured in the following sequence.
Ore from Earth → Reducing processes → Molten metal → Commercial Castings → Ingots → Further Processes → Usable product of different shapes and sizes.
All these further processes used for changing the ingots into usable products can be classified as follows :
1. Primary Shaping Processes 2.Machining Processes
3..Joining Processes 4.Surface Finishing Processes
5.Processes effecting change in properties
Compound Stress: Define Compound Stress. Sol.: Simple stresses mean tensile stress or compressive stress or shear stress. The tensile and compressive stresses act on p
Steam flowing at a rate of 3200 lbm/hr enters an adiabatic nozzle. The initial condition of steam is: P1 = 250 psi, v1=620 ft/min, v1 = 2.4 ft3/lbm and u1 = 1125.5 Btu/lbm. The ste
Design Standards: The following design standards for a modern airport facility catering to latest models of aircraft may be noted for guidance.
Steel Rule: A steel rule is used to measure length. It has two scales - in millimeters and inches. These rules are available in market in discrete lengths such as 15, 30, 60 cms.
