Feed speed calculator
Feed speed notes
Feed speed is not chosen independently. It is calculated from spindle speed, chip load, and number of cutting edges. Adjust it for radial engagement, axial depth, runout, and chip evacuation.
FAQ
Are these chart values final production recommendations?
No. They are starting values for planning. Use the specific cutting tool manufacturer data, workholding condition, coolant method, and machine limits before running production parts.
Why do different speed and feed charts disagree?
Charts assume different tool materials, coatings, tool life targets, rigidity, coolant, radial engagement, and material hardness. A generic chart should be adjusted to the actual tool and setup.
Why does feed speed change when RPM changes?
Chip load is per tooth per revolution. If RPM increases and chip load stays the same, feed speed must increase to keep the same chip thickness.
Should I reduce chip load for slotting?
Often yes. Full slotting increases tool engagement and chip evacuation difficulty, so many setups need lower feed, lower radial engagement, or better chip clearing.
Data sources and limits
These charts are starting values only. Actual speeds and feeds depend on tool geometry, coating, holder rigidity, coolant, chip evacuation, radial width of cut, axial depth of cut, material hardness, and machine power.
