1. What is Constant For Machine Type B?

Constant For Machine Type B is a parameter used in machining calculations that represents specific characteristics of the tool material and its interaction with the workpiece material during machining operations under maximum power conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ b = 1 - \frac{\ln(\rho \cdot a \cdot t_p) - \ln(V_0 \cdot p_s)}{\ln(W)} \]

Where:

\( b \) — Constant for tool type b
\( \rho \) — Density of work piece (kg/m³)
\( a \) — Constant for tool type a
\( t_p \) — Machining time for maximum power (seconds)
\( V_0 \) — Proportion of initial volume
\( p_s \) — Specific cutting energy in machining (J/m³)
\( W \) — Initial work piece weight (kg)

Explanation: The formula calculates the constant b by considering the natural logarithms of various machining parameters and their relationships.
