1. What is Reference Tool Life?

Reference Tool Life is the Tool Life of the tool obtained in the reference machining condition. It represents the expected lifespan of a cutting tool under specific reference conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ L_{ref} = \left(\frac{V}{V_{ref}}\right)^{\frac{1}{n}} \times (1-n) \times \frac{C_t \times t_c + C_t}{n \times C_t} \]

Where:

$ V $ — Cutting Velocity (m/s)
$ V_{ref} $ — Reference Cutting Velocity (m/s)
$ n $ — Taylor's Tool Life Exponent
$ C_t $ — Cost of A Tool ($)
$ t_c $ — Time to Change One Tool (s)

Explanation: The formula calculates reference tool life based on cutting velocity ratio, tool life exponent, and economic factors including tool cost and change time.

3. Importance of Reference Tool Life Calculation

Details: Accurate reference tool life calculation is crucial for optimizing machining processes, predicting tool wear, and minimizing production costs in manufacturing operations.

4. Using the Calculator

Tips: Enter all values in appropriate units. Cutting velocities must be positive values, Taylor's exponent should be between 0 and 1, and all economic parameters must be positive numbers.
