Production process

Production is a process, and as such it occurs through time and space. Because it is flow concept, production is measured as a “rate of output per period of time”.

This subject would be most useful for Polytechnic as well as Engineering student of all universities, AMIE student, for appearing theory examination, practical examination, and oral and to face interviews.

This subject will cover the topics like Foundry, Mechanical working of metals, Sheet metal working, Processing of plastics, Joining processes, Surface treatment, Lathe, Milling machine, Shaper slotter and planer, Introduction metal cutting and cutting tools advances, Drilling boaring and grinding machines, Nontraditional machining.
