Lindsay's Semiempirical Analysis provides a mathematical model to estimate the percentage volume of bond material in grinding wheels. This analysis considers various grinding parameters to predict the optimal bond material volume for efficient grinding operations.

2. How Does the Calculator Work?

The calculator uses Lindsay's semiempirical formula:

Where:

\( v_w \) — Surface speed of workpiece (m/s)
\( v_t \) — Surface speed of wheel (m/s)
\( a_d \) — Depth of dress (m)
\( f \) — Feed (m)
\( d_e \) — Equivalent wheel diameter (m)
\( \Lambda_t \) — Wheel removal parameter
\( d_g \) — Grain diameter of the grinding wheel (m)
\( N_{\text{hardness}} \) — Rockwell hardness number
