Abstract
Metal cutting processes usually cause heat generation at the cutting zone (around
the workpiece-tool intersection). The heat generated during these processes may
cause different effects on both the workpiece and tool, this in turn may affect the
finished product and the general performance of the machined piece. In this
study, a review was done on various types of machining conditions available,
effects of heat generated on the workpiece and tool, and the approaches adopted
to reduce this heat at cutting zones. This study also focuses on the simulation of
percentage ratio of heat removal. To handle the simulation, various approaches of
heat removal methods were used to get the percentage ratio using the ansys
version 19.1 software. It was discovered that heat generation causes two major
types of wear on the tool, crater and flank wear, resulting in the reduction of
cutting tool life as well as dimensional inaccuracy, surface damage and severe
corrosion cases on the workpiece. Various heat reduction methods and coolant
application types were as well studied and their merits and demerits were
discussed.
