Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Taylor’s Tool Life Equation based on Flank Wear:
VTn = C
Where, V = cutting speed (m/min)
T = Time (min) (time taken to develop certain flank wear)
n = an exponent that largely depends on tool material
C = constant based on tool and work material and cutting condition.
