Frequently asked questions
Can this result be used directly on a CNC machine?
Use it as a starting value only. Check the tool manufacturer data, machine limits, workholding, coolant and material condition before production.
Which units does the calculator support?
The calculator shows the units beside each input. Select metric or inch units where the page provides a unit-system control.
Why can shop results differ from the calculation?
Tool geometry, coating, runout, rigidity, chip evacuation, material hardness and machine power can change the practical result.
