Speed & feed calculator
Enter the tool and cutting data. Results update as you type. Pick a material below to load starting values.
Spindle speed n
4,775min⁻¹
Feed rate vf
955mm/min
Metal removal rate Q
28.6cm³/min
Max. chip thickness hex
0.0458mm
Chip thinning: With ae < D/2 the chip gets thinner than fz. To keep the chip thickness of fz, increase the feed per tooth to fz = 0.0546 mm (vf = 1,042 mm/min).
Ball-nose end mill
Effective diameter at depth ap and scallop height at step-over ae.
Effective diameter Deff
10mm
Effective cutting speed
150m/min
Scallop height h
230.3µm
Starting values — solid carbide end mills (coated, side milling)
