Abstract
This work analyzed the performance of an adopted Internally Cooled Tool Holder – ICT. in a closed loop during the turning operation of an ABNT 1045 Steel. The input variable was the ambient ICT and dry machining, while feed rate (f = 0.40 mm/rev), rotation (n = 1 020 rpm) and depth of cut (doc = 0.4 mm) were kept constant. The output variables were roughness (Ra), quantitative and wear mechanisms, qualitative. The main conclusions are that dry and I.C.T. conditions for roughness had the same statistical results, indicating that I.C.T. does not act over the workpiece. The tool's wear analysis observed micro chippings, adhesion, and plastic deformation (flank wear) for both dry and I.C.T. However, the wear was much more pronounced in dry conditions, indicating that I.C.T. helps keep the tool cool, preserving it. Finally, I.C.T. showed to be a promising sustainable, eco-friendly technique. However, complementary studies are necessary.
