Machine Design

Machine Design or Mechanical Design can be defined as the process by which resources or energy is converted into useful mechanical forms, or the mechanisms so as to obtain useful output from the machines in the desired form as per the needs of the human beings. Machine design can lead to the formation of the entirely new machine or it can lead to up-gradation or improvement of the existing machine. For instance if the existing gearbox is too heavy or cannot sustain the actual loads, entirely new gearbox can be designed. But if the same gearbox has the potential to lift more loads, it can be upgraded by making certain important changes in its design.

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:

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.
