Formulas to calculate work parameters for HSS end mills d = end mill diameter (mm) Vc = cutting speed (m/min) n = number of revs per minute (rpm) of the end mill fz = progress per tooth (mm) z = number of cutting edges on the end mill f = feeding speed (mm/min) fzf = feeding speed value for the drilling operation with end with central cutting edge end mills V c =  × n × d 1000 n = 1000 × V c  × d f = f z × z × n f zf = f z × 0,3 Type of material Resistance to traction or hardness of the material Examples of materials Cutting speed in m/min (Vc) End mills with 2/3 cutting edges Rough end mills Radial end mills End mills for aluminium Finishing end mills 4/6 cutting edges Normal Coated Normal Coated Normal Coated Normal Normal Coated Construction steel ≤ 600 N/mm 2 S185, StEP275N, P235GH, P265GH, E295, E360, P500NH 35-60 60-70 40-55 65-75 35-50 60-70 40-55 65-75 Nitride steel 850-1000 34 CrAl6 28-38 45-55 26-28 45-50 28-38 45-55 14-20 20-30 Tool steel, high speed steel ≤ 1000 N/mm 2 C75, 102Cr6, 29CrMoV9, S6-5-2-5, 61CrV4 25-35 40-50 22-24 37-45 25-35 40-50 28-40 42-50 Tool steel, alloy steels ≤ 1100 N/mm 2 X210Cr12, X42Cr13, 105WCr6, 14NiCr14, 16MnCr5 12-18 25-35 10-12 18-22 12-18 18-28 14-20 20-30 Stainless steel ≤ 850 N/mm 2 X12CrS13, X14CrMoS17, X5CrNi18 10, X6CrNiMoTi17 12 2, X2CrMoTi18 2 28-38 45-55 26-28 45-50 28-38 45-55 18-22 28-38 Cast iron, spheroidal cast iron, hardened cast iron <280 HB EN-GJL-100, EN-GJL-300, EN-GJMW-340-5, EN-GJL-300 26-30 42-52 22-28 42-48 26-30 42-52 30-35 45-55 Special alloys ≤ 1400 N/mm 2 Inconel, hastelloy, Nimonic 6-8 8-14 6-8 8-12 6-8 8-14 7-10 10-16 Titanium ≤ 750 N/mm 2 Ti99.5 30-40 55-65 30-34 70-75 30-40 55-65 32-45 60-70 Titanium and titanium alloys ≤ 1400 N/mm 2 Ti Al6Zr5, TiAl6V4, TiAl8Mo1V1 6-8 8-14 6-8 8-12 6-8 8-14 7-10 10-16 Low % copper alloy ≤ 500 N/mm 2 SE-Cu, CuSn6, G-CuSn5ZnPb 100-150 150-300 70-100 80-100 70-100 80-100 Brass ≤ 600 N/mm 2 CuZn39Pb2,CuZn39Pb3 100-150 150-300 70-100 80-100 70-100 80-100 Bronze ≤ 600 N/mm 2 CuAl5, CuAl11Ni 100-150 150-300 70-100 80-100 70-100 80-100 Aluminium and aluminium alloy ≤ 450 N/mm 2 Al99.5, AlMg1, AlMgSiPb, AlZnMgCu1.5 200-400 400-600 100-250 120-250 Magnesium and magnesium alloys ≤ 450 N/mm 2 MgMn2, G-MgAlZn1, G-MgAl6Zn3 200-400 400-600 100-250 120-250
