1. What is Machining and Operating Rate Spindle Speed?

Machining and Operating Rate spindle speed is the money charged for processing on and operating machines per unit time, including overheads. It represents the cost efficiency of machining operations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M_s = \frac{C_t}{\left( \frac{V_{ref}}{2\pi R_o \omega_s} \right)^{\frac{1}{n}} \times \frac{1+n}{1-n} \times \frac{1-R_w}{1-R_w^{\frac{n+1}{n}}} \times T_{ref}} - t_c \]

Where:

$ M_s $ — Machining and Operating Rate Spindle Speed ($)
$ C_t $ — Cost of a Tool ($)
$ V_{ref} $ — Reference Cutting Velocity (m/s)
$ R_o $ — Outer Radius of Workpiece (m)
$ \omega_s $ — Rotational Frequency of Spindle (Hz)
$ n $ — Taylor's Tool Life Exponent
$ R_w $ — Workpiece Radius Ratio
$ T_{ref} $ — Reference Tool Life (s)
$ t_c $ — Time to Change One Tool (s)

Explanation: This formula calculates the optimal machining and operating rate by considering tool costs, cutting parameters, and tool life characteristics.
