1. What is Taylor's Tool Life Exponent?

Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of tool wear. It is a crucial parameter in machining operations that relates cutting velocity to tool life.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ n = \frac{\ln\left(\frac{V}{V_{ref}}\right)}{\ln\left(\frac{L_{ref} \cdot V \cdot (C_p - M \cdot (NPT + \frac{K}{V}))}{K \cdot (M \cdot t_c + C_t)}\right)} \]

Where:

$ V $ — Cutting Velocity (m/s)
$ V_{ref} $ — Reference Cutting Velocity (m/s)
$ L_{ref} $ — Reference Tool Life (s)
$ C_p $ — Production Cost of Each Component ($)
$ M $ — Machining And Operating Rate ($/s)
$ NPT $ — Non-Productive Time (s)
$ K $ — Constant For Machining Condition (m)
$ t_c $ — Time to Change One Tool (s)
$ C_t $ — Cost of A Tool ($)

Explanation: This formula calculates Taylor's Tool Life Exponent based on various machining parameters and cost factors.
