Azlan Suhaimi Abstract Electrical energy is directly linked to societys prosperity across the globe; much of this due to the diverse innovations on manufacturing processes. Keeping pace with the high energy demand g

3、rowth will require constant efforts in terms of investment and research in order to bring new alternatives of usage. This paper outlines the application of multiple response optimization in order to analyze the trade-off be- tween machining time and energy consumption in 5-axis impeller rough machin

4、ing to nd a possible balance between them. It is well known that a higher speed reduces machining time but increases energy consumption, and vice versa. A quantitative form of the relationship between the involved factors was obtained by utilizing response surface methodology (RSM) together with the

5、 desirability function method. Four independent factors were selected, namely, spindle speed, feed rate, depth and width of cut. The responses are the consumed energy and the machining time. The results showed that selecting an appropriate feed rate is crucial to balance the trade-offs between energ

6、y and time. Spindle speed is the major factor for energy consumption, while width of cut is the most inuential factor for machining time. Keywords: Energy consumption ; Machining time ;Impeller 1. Introduction Energy efciency has increasingly become a relevant issue in recent years due to the economic and environmental factors involved. Industries are aware of the importance of the energy usage because of costs savings or environmental regulations. Machining is one of the major activitie
