Abstract
Recently, some activities for environmental protect have been tried to reduce environmental burdens in a lot of fields. Manufacturing field is also required to reduce them. Hence, prediction system of environmental burden for machining operation is proposed based on LCA (Life Cycle Assessment) policy for future manufacturing system in this research. This system can calculate environmental burden (equivalent CO2 emission) due to electric consumption of a machine tool, cutting tools, coolant, lubricant oil, metal chips and provide the information of accurate environmental burden of machining process by considering some activities related to machine tool. In this paper, the development status of prediction system is described. As a case study, two NC programs that manufacture simple shape are also evaluated to show the feasibility of it.
