The Purpose of Machine Design Course
The course in Machine Design help students understand the fundamentals of designing the most commonly used parts, elements and units of various machines. Small components of machine on assembling make a big machine, hence the machine as a whole as well as its individual components have to be designed.
The knowledge of machine design helps the designers as follows:
1) To select proper materials and best suited shapes,
2) To calculate the dimensions based on the loads on machines and strength of the material,
3) Specify the manufacturing process for the manufacture of the designed component of the machine or the whole machine.
Machine Design is the application of: mathematics, kinematics, statics, dynamics, mechanics of materials, engineering materials, mechanical technology of metals and engineering drawing. It also involves application of other subjects like thermodynamics, electrical theory, hydraulics, engines, turbines, pumps etc. Machine drawing is the integral part of the machine design, since all the components or the machines that havmachine designd should be drawn to manufacture them as per the specifications. Without machine drawing the subject of machine design is incomplete.
