An experiment-based investigation on the partitioned distribution of cutting heat and cutting temperature in micro cutting

Abstract

This paper presents the scientific understanding of cutting temperature and partitioned heat distribution in micro cutting based on experimental-based investigation on micro cutting titanium (Ti-6al-4v), Aluminium (Al 6082-T6) and silicon. It is found the conductive heat partitions at the tool/tool tip - workpiece are 8/8.5 : 1 and 14/16: 1 in cutting aluminium and silicon respectively and 350/460 : 1.4 : 1 (tool/tool tip - chip - workpiece) in cutting titanium.
