Experimental Research on Cutting Heat Dissipation under Various Cooling Conditions

Abstract

Cutting heat dissipation in high speed milling of medium carbon steel was experimentally investigated based on calorimetric method under the cooling conditions of hard cutting, applying compressed air or water. Special containers holding water medium were designed to collect cutting heat in chips, workpiece and tool respectively, and the heat distribution ratio in these components was calculated in terms of the temperature varieties of each component. The results were compared with the cutting power which came from the cutting forces measured.
