First Level Thermodynamics Study of Manufacturing System Holistic Method of System Description ….. P M V Subbarao Professor Mechanical Engineering Department I I T Delhi

Need for a Holistic Study Present study is using a thermodynamic framework to characterize the material and energy resources used in manufacturing processes. The analysis must span a wide range of processes: “Conventional” processes: –Machining –Casting – Forming –Injection molding … “Advanced machining” processes: –Electrical discharge machining –Abrasive waterjet machining, –Vapor phase processes used in semiconductor and nanomaterials fabrication.

Holistic Vision of Engineering Analysis Primitive concepts Accept Theory Secondary concepts Propose Theory Test Theory Impact on Society Industrial Processes Engineering Relations Particular Relations INDUCTION DEDUCTION

Application of Thermodynamics Available Resources (Energy, matter etc.,) Engineering of Manufacturing processes, devices and systems. Is Design meeting Human’s NEED? YES (task completed) NO Thermodynamics Laws and information Fluid Mechanics & Heat Transfer etc,.. Social Sciences and Humanities

New Ideas for Same Need Development of A Display system What fundamental quality of the substance is to be identified to select right idea to achieve the objective ?
