3.4.1. T1—Flank Wear Measurement

In this subsection, the wear measurement values, performed on the clearance faces of all the tested T1 tools, are presented in Table 12.


From the values presented in Table 12, it was concluded that the increase in cutting length caused a slight increase in flank wear. However, it was a very small increase, especially when compared to the variation in flank wear that was observed with feed variation. For the lower feed rate, the tools presented slightly more flank wear than those that were tested at a 100% feed rate. There was also an increase in flank wear for higher feed rates; however, these feed rates produced the most severe wear, with high values of flank wear being registered at these values of feed rate when 2- and 4-m cutting lengths were used. In terms of a less amount of wear, this was obtained under the original cutting condition, with the lowest amount of wear being registered for T1L2F100 and followed by T1L4F100, indicating that the machining parameters were well defined for this tool in terms of wear behavior.
