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.
