Feed per Revolution
Feed per revolution is the amount of material the cutting tool removes with each revolution of the workpiece or tool. This parameter is key in processes like turning, drilling, and milling, where tools rotate relative to the material.
Importance of Feed per Revolution
Surface Finish - A lower FPR generally results in a smoother surface finish.
Tool Life - The right FPR ensures optimal wear on the cutting tool, extending tool life.
Machining Efficiency - Adjusting FPR can balance material removal rate with tool durability.

\( FPR \) = Feed per Revolution | \(in\;/\;rev\) | \(mm\;/\;rev\) |
\( TF \) = Table Feed | \(in\;/\;min\) | \(mm\;/\;min\) |
\(SS\) = Spindle Speed | \(rev\;/\;min\) | \(rev\;/\;min\) |
