Developing a dynamic model of energy consumption for CNC machines in automotive industries helps to reduce the energy consumption in these machines. Over the last decade, a significant rise in energy usage has occurred due to the growth in the developing world. According to (IEO2013), this trend will continue over the next three decades. In CNC machines, there are various parameters in milling and turning operations which have significant roles in reducing energy consumption. In the first case study presented, parameters of machine tools are changed and the energy consumption is calculated to identify the parameters that have the greatest impact on saving energy. An energy consumption model is developed by using system dynamics in order to comprehend the behavior of complex system. Then, data from the first case study is used in order to demonstrate how buffer inventories can help manufacturers to save more energy during high electricity demand.
