Useful mathematical formulas

To optimize the processing parameters, formulas are used such as:

• Cutting speed (Vc) : Vc=(π⋅D⋅n)/1000Vc = (\pi \cdot D \cdot n) / 1000 $V$ $c$ $=$ $($ $\pi$ $\cdot$ $D$ $\cdot$ $n$ $)$ $/1000$ , where DD $D$ is the diameter of the workpiece (mm) and nn $n$ the spindle speed (rpm).
• Feed (F) : F=n⋅fF = n \cdot f $F$ $=$ $n$ $\cdot$ $f$ , with ff $f$ equal to the feed per revolution.
