With measured results, several researches have conducted to
implement energy saving concepts in CAD/CAM systems
(Christoffersen et al., 2006), and also to minimize gap between
industrial needs and scientific approaches (Bunse et al., 2011).
Avram and Xirouchakis (2011) performed energy consumption
assessment of machine tool system, and examined a power prediction
by CAD/CAM software. From the perspective of process planning, Rangarajan and Dornfeld (2004) investigated the energy
consumption during metal machining in terms of part orientation,
and Kong et al. (2011) evaluated the tool path in terms of environmental
factors. Hsieh et al. (2003) conducted optimized
scheduling of drilling operations to provide a minimum time solution.
Deif (2011) suggested a planning model for green
manufacturing and sustainability. Following those research trends,
power measurement and control technologies of manufacturing
facilities have been expected to keep growth for energy optimization
and also for condition monitoring of a process (O’Driscoll and
O’Donnell, 2013).
