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.
