Abstract
Prediction and control of undesirable deterioration of cutting tools are the most essential challenges emanating in the design of tool which has to be checked. As a result of an increase in wear rate of HSS cutting tools, so has the need for wear resistant. The result has been a progression of carburizing the tools for better performance. Based on the theoretical analysis and study of tool wear and parameters that mitigates against wear resistance of cutting tools, this research work presents an experimental investigation and analysis of the wear properties of carburized HSS cutting tools. Twelve Samples under consideration were carburized HSS (ASTM A600) tools (0.65% C) treated at 800,850,900 and 950oC with holding time of 60, 90 and 120 minutes respectively. The wear properties of weight loss, wear volume, wear resistance and wear rate were carried out using Rotopol –V, impact tester, polisher, grinder and weight scale. It was found from the experiment carried out that cutting tool(sample 5) carburized at holding temperature and time of 800 oC and 90 minutes has the lowest cutting weight loss, volume and wear rate of 0.002 g, 0.00026 cm3 and 5.476 X10-10 cm2 with maximum wear resistance of 1.83X109 . This showed that sample 5 has the best wear properties which undermined the general believe that the sample with highest holding temperature and time should have the highest wear properties. This experiment has further established carburization as one of the heat treatment methods that involved carbon penetration to the depth that improved wear rate and resistance of a material.
