Machining tools' longevity and optimal
performance are prevalent problems in manufacturing.
Instrument failure can result in significant financial
losses, especially for small-scale manufacturers. Thus,
this paper investigates the effects of temperature on the
cutting edge to guide the design of effective cutting tools
and processes. An integrative literature review was used
to compile relevant insights from different researchers.
Four articles were sourced from Google Scholar using
appropriate selection criteria. An assessment of the
findings in the papers indicated two major effects of
temperature on the cutting edge: wear and thermal
cracking. The former is due to the reduced hardness and
yield strength, while the latter originates from the
thermal shocks and stress imbalance caused by cyclical
heating and cooling.
