the framework. This paper also will appear in the Journal of Manufacturing Systems (http://tinyurl.com/NAMRC-JMS). Several MSEC papers focused on sustainable manufac- turing metrics and methods. Pil-Ho Lee, Dae Hoon Kim and Sangwon Lee of Sungkyunkwan University (Suwon, Korea) demonstrate that a new hybrid system using electro-hydro- dynamic (EHD) spray lubrication with chilly air reduces milling forces and burrs significantly. An atomization-based cutting fluid (ACF) spray system is proposed as a cooling and lubrica- tion solution for machining hard-to-machine materials (e.g., titanium alloys) in a paper by Alexander Hoyne, Chandra Nath and Shiv Kapoor of the University of Illinois at Urbana-Cham- paign. On the tool rake face, the ACF spray system forms a thin film from cutting fluid that penetrates into the tool-chip interface to improve tool life.


Also from MSEC, Jatinder Madan, Mahesh Mani and Kevin


Lyons of the National Institute of Standards and Technology (NIST; Gaithersburg, MD) present a science-based guideline


to characterize energy consumption for a part manufactured using the injection molding process. They discuss selection of process parameters and manufacturing resources, determina- tion of cycle time, theoretical minimum energy computations and estimated energy computations. Because many energy- saving opportunities are wasted by lack of integration between the facility and the production system, Michael Brundage and Cindy Chang of Stony Brook (NY) University and Dongmei Chen and Victor Yu of the University of Texas-Austin propose syncing the energy opportunity window of each machine with peak periods of energy demand of the HVAC system. Sustainable vehicle manufacturing was covered in two MSEC papers. Chongye Wang, Yong Wang and Lin Li of the University of Illinois-Chicago, Hua Shao of Shanghai Jiao Tong University (China) and Changxu Wu of the State University of New York at Buffalo examine the effects of manufacturing processes on the performance of entire electric vehicle (EV) lithium-ion (li-ion) battery packs while proposing a novel mod-
