Investigation of Specific Cutting Energy at low speed turning of Al 6061 T6

Abstract

Machine tools are accountable for environmental influence owing to their energy consumption. It is also a challenge for modern manufacturing how to reduce the environmental impacts related to machining processes. The environmental study about machine tool that used in machining reveals that more than 99% of environmental impacts are due to the consumption of electrical energy. This research presents the energy consumption map at low cutting speed of Aluminum alloy Al 6061-T6. The constructed energy map tells about different energy consumption regions at different machining parameters (feed and speed) during single point cutting of Al 6061-T6 alloy. In this thesis, less energy consumption observes at cutting speed (in the ranges of 500-1000 m/min) and at higher feed (in the ranges 0.3-0.45). Designs of experiments were done with the help of full factorial. Aluminum alloy 6061-T6 used as a work-piece material and it is widely used materials in automobiles, aerospace, defense and bio-medical industries. All these experiments were performed by using fresh cutting inserts, that’s why the effect of tool wear was not considered for power and energy measurements. The main purpose of this research is to investigate the energy consumption and developed the energy map. The presented map can be used for selection of the parameters which are efficient for SCE.
