TurningMillingDrillingTechnicalInformationIndex ap ap Technical information Technical information – milling A Solid carbide millsMachining strategy – HPC/UM (HSC) milling cutters HPC = High Performance Cutting Machining with significantly increased metal removal rate through higher cutting speeds and feed rates compared with conventional machine cutting processes. ae Full-slot milling B HSC (UM) = High Speed Cutting High cutting speeds and feed rates in combination with low cutting depths lead to lower chip thickness as in normal machining. ae C ae <15 %ap = max Profiling Trochoidal milling The UM milling cutter is specifically optimised for HSC machining. β2 D α2 β1 β1≠β2 α1 α1≠α2 High metal removal rates can be realised with this tool. Especially on highly dynamic machines with optimised tool paths this milling cutter shows its full potential. E B 474
