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.
