Abstract: Although the low cutting temperature and a small amount of heat generated are occurred in micro cutting, they are comparably high in a small unit cutting area or zone, and consequent affect the micro cutting process significantly. Thus, such low cutting temperature in micro cutting can cause an excessively dissipated heat into cutting process including chip, workpiece and especially diamond tool tip. This excessive heat leads to thermal effects and consequent severe tool wear or breakage, and therefore, poor quality of machined surfaces and products. This paper presents the scientific understanding of cutting temperature and heat partitioned distribution in micro cutting based on experimental investigation on cutting of titanium (Ti-6Al-4V), aluminum (AA6082-T6) and single crystal silicon. The further supported with FE-based simulations on aluminum (AA6082-T6) are conducted. The paper includes with research findings of the heat partitioned distribution on tool/tool tip against workpiece of aluminium, silicon and titanium cutting, respectively.
