Análise da Usinabilidade da Liga Al-7%Si Solidificada em um Sistema Unidirecional Horizontal

Abstract

Machining is probably the most widely used manufacturing process, and metals and alloys form a large percentage of machined materials. During the machining process, a considerable amount of the machine energy is transferred into heat, and the cutting temperature is of fundamental importance. This research investigates the influence of solidification thermal parameters and the secondary dendritic arm spacing (λ2) of an Al-7wt%Si alloy solidified on a transient horizontal directional device on the cutting temperatures during turning bleeding. Experimental power function laws relating cutting temperature with cooling rate, solidification rate, and secondary dendrite arm spacing were developed.
