Manufacturing process are not considered in detail in (Life-Cycle Assessment) LCA. Recently, the environmental impact of machining in LCA is determined from the rough volume material removed or weight ratio of construction material only. In this study, LCA in machining process can be related to energy and design feature by a linkage called Life-Cycle Design (LCD). Specific Energy Consumption (SEC) from various combination of machining parameter can be used to evaluate machining process in detai l from design stage. Present study is an experimental study to get SEC from various combination of machining parameter. The focus of the experiment is turning process, with a combination of spindle speed, and feed rate setting. This data is useful in analysis of environmental impact in machining process at the design stage.
