Choosing the Correct Cutting Speed

How work material, tool material, diameter and machine rigidity affect cutting speed.

The practical idea

Cutting speed describes the relative surface movement between the cutting edge and the work. Appropriate speed depends on workpiece material, tool material, coating, coolant, machine rigidity and the type of operation.

What changes the real result?

Start from trustworthy tool-manufacturer data, then reduce the starting value for uncertain workholding, interrupted cuts, long overhang or limited coolant.

A reliable workflow

  1. Confirm the units, material and operating conditions.
  2. Use a suitable formula or reference as a starting point.
  3. Compare the estimate with manufacturer data and applicable standards.
  4. Measure the real result and record any corrections for repeat work.
