Consumo de energia no processo de furação do alumínio 6061-t6

Abstract

The activities of the production sector related to the manufacturing industry are responsible to a significant portion of the energy consumption nowadays. Knowing that the machining processes are largely used techniques for production and that, also, great effort has been done to mitigate the environmental impacts caused by the consumption of these processes, the present study has, as the main goal, the analyze of experimental data of energy consumption of High Speed Steel (HSS) twist drills used to drill the Aluminum alloy 6061-T6, in order to understand better and optimize the process, reducing the energy consumption and contributing for a more sustainable production. The results found suggest that the demand for energy increases when the feed rate gets higher; the peck drilling technique (technique of vertical movement to break chips and lubricate the workpiece) has similar energy consumption when compared to the use without it in the cutting conditions described here in this work. The energy consumption is affected by cutting area and is related to the feed rate; the tool wear for the quantity of holes made has insignificant values in the energy consumption.
