Manufacturing Process Technology I

Manufacturing Process Technology I. Instructor: Prof. Shantanu Bhattacharya, Department of Mechanical Engineering, IIT Kanpur. This is an introductory level course in Manufacturing Process Technology. At the heart of any manufacturing system is a set of processes which change the size, shape and form of raw materials into the desirable thus giving an industrial nation the power of growing. This course is an introductory course for engineering professionals who would like to take up careers in manufacturing particularly at the process level and also for professionals who are already in manufacturing careers and would like to see the technological changes that the manufacturing processes have witnessed in the last about 5 decades.
