Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation. * Recommended feed rate is the reference value when ap is r/2 (3mm for ROMU12, 4mm for ROMU16). For lower ap than the above conditions, the conversion factor in the following table is recommended. ap Conversion factor for feed per tooth fz M Insert (recommended) Max. ap ap=0.5mm ap=1mm ap=2mm ap=3mm ap=4mm ROMU12 type 3mm or less 6mm 2.1 1.5 1.1 1.0 － (Standard) ROMU16 type 4mm or less 8mm 2.4 1.7 1.3 1.1 1.0 (Standard) Milling * Example (ROMU12 type, Carbon Steel, GM chipbreaker, ap=1mm) fz=0.2mm/t × 1.5 = fz=0.3mm/t (Reference value for carbon steel and GM chipbreaker) (Conversion factor for ROMU12 type, ap=1mm) (Recommended feed rate) Inserts * Recommended ap: 3mm or less for ROMU12, 4mm or less for ROMU16 Lead Angle Except the case that ap temporally surpass the recommended ap, machining under the recommended ap is recommended. 45°/20° Corner-R shape during processing Y (Gap between insert corner-R) Lead Angle Corner-R shape during processing with MRW (Ref. to the right figure) 15° Lead Angle Insert Max. ap X Y 0° High Feed Insert corner ROMU12 type 6mm 3mm 0.1mm Multi- Function ROMU16 type 8mm 4mm 0.1mm Slot Mill X (Recommended ap) Max. ap（max.） * When machining with larger ap than recommended ap (X), there is a gap (Y) between the workpiece corner and insert corner-R(r).
