Q. In a typical turning tool life test, the following data are generated for tools A and B:
| Tool name | Cutting speed (m/min) | Tool life (min) |
| A | 200 | 20 |
| B | 150 | 58 |
Assuming the same tool life exponent for the tools, the value of constant in the Taylor’s tool life equation (with cutting speed in m/min and tool life in min) is ______________(round off to 2 decimal places)
Ans: 445 – 455
Sol:
Taylor’s Tool life Equation:
V × Tn = C
Where,
V = Cutting Speed, T = Tool Life, C = Constant.
Calculation:
