Tool Life for Maximum Production
Tool Life for Maximum Production - By analogy to Taylor's equation, the tool life that corresponds to the maximum production rate is given by:
Tmax = (1/n -1) tc
The tool life at maximum production rate is a function only of n, the slope of the curve in Taylor's equation, and the tool changing time. Thus, for an HSS tool (n = 0.1) with a tool changing time of 1 min, Tmax = 9 min; that is, the tool should last only 9 min. A carbide tool, where n = 0.25 and 1 min is needed for tool changing, should only last 3 min.
