Effect of cutting parameters and machining environments on the chips characteristics and surface quality of commercial high-conductive materials

Abstract

The present paper is on the physical and mechanical characterization of machined chips of commercially available highly conductive metallic materials, namely aluminium and copper under different machining environments. More specifically, geometry and hardness of chips as well as the chips removal effect on the machined surfaces are investigated in a quantitative fashion as a function of machining fluid and cutting parameter. The machining is carried out by using a horizontal shaper machine with a V-shaped HSS tool under three different machining fluids, where the feed rate is kept constant, while the cutting speed and depth of cut are varied. The geometry and hardness of the machined chips as well as the quality of machined surfaces are found to be affected quite significantly by the change of machining condition, particularly by the machining fluids.

Role of Si on machined surfaces of Al- based automotive alloys under varying machining parameters

“…Heat generated during machining could result in the softening of the material and, thus, lowered cutting forces. Again, shorter chips are always expected because continuous chips sometimes stick with the tool, cause damage to the surface quality and unexpected injury may occur [14].…”
