Abstract
In this work, a new innovative technique was proposed using the concept of Internally Cooled Tool – ICT with a closed-loop, i.e., without any fluid dispersion to the atmosphere. A study was carried out on the behavior of ICT carbide tools during the turning of Cast Gray Iron -CGI made by Continuous Casting. The cutting forces were chosen as the output response variable to understand this behavior using this novel ICT technique. The input variables were ambient (Cutting Fluids in Abundance – CFA and ICT), cutting speed (40, 60, 80,100, 120, 160, 200, 240, 360, 480 and 600 m/min). The depth of cut (doc) and feed (f) were kept constant at 1.0 mm and 0.1 mm/rot, respectively. The mains finding were that cutting forces were higher in all conditions for ICT due to its exceptional cooling capacity that acts removing heat from the cutting zone, reducing the temperature and the material softening effect, and the poor lubricating capacity that turns chip difficult to remove. It is a complementary study of previously published ICT techniques.
