Study of Tool Wear Process in the Dry Turning of Al-Cu Alloy

Abstract

Light alloys machining is a widely implemented process that have usually used in presence of cutting fluids to reduce the wear impact and increase tool life. However, current environmental protection policies require their elimination in order to improve process sustainability. This fact forces to work under aggressive cutting conditions, producing adhesion wear that affects the integrity of the part surface. This study describes cutting tool wear mechanisms in machining of UNS A92024 samples under dry cutting conditions. EDS analysis showed the different composition of the adhered layers, while roughness was also positively affected by the change of the cutting geometry produced in the tool.

The relationship between adhesion morphology and cutting force in orthogonal cutting of 6061-T6 aluminum alloy

“…In terms of the influence of adhesion, Gomez-Parra discovered that as the BUE increased, the surface roughness of the machined surface decreased. In response to this phenomenon, Batista [12] pointed out that this is because the formation of a BUE changes the tool surface topography and geometry. The degree of adhesion increases as the cutting time grows, which influences the tool geometry and in turn, causes the machined surface roughness to decrease as the cutting time increases.…”

Evaluation of Self-Propelled Rotary Tool in the Machining of Hardened Steel Using Finite Element Models

“…Nevertheless, on the one hand, the excellent properties of these materials are advantageous, on the contrary, they pose obstacles and difficulties in the machining of these materials. The serious challenge that arises when such materials are being machined is intense heat emission which in turn influences the wear and machining efficiency of the tool [ 1 , 2 , 3 ].…”
