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 D.O.C. is RE/2 (0.118" for ROMU12, 0.158" for ROMU16). For lower feed rates than the above conditions, the conversion factor in the following table is recommended. Conversion Factor for Feed Per Tooth by Depth of Cut (D.O.C.) Insert D.O.C. (Recommended) D.O.C. (Max.) Conversion Factor for Feed Per Tooth D.O.C. = 0.020" D.O.C. = 0.039" D.O.C. = 0.079" D.O.C. =0.118" D.O.C. = 0.158" Inserts ROMU12 Type 0.118" or less 0.236" 2.1 1.5 1.1 1.0 (Standard) - 45°-70° Lead Angle ROMU16 Type 0.158" or less 0.315" 2.4 1.7 1.3 1.1 1.0 (Standard) 75° Lead Angle Calculation Example (ROMU12, Carbon Steel, GM Chipbreaker, D.O.C. = 0.039") 90788° Lead Angle High Feed Cutter fz = 0.008 ipt (Standard value for carbon steel and GM chipbreaker) X 1.5 (Conversion factor for ROMU12 type, D.O.C. = 0.039") fz = 0.012 ipt (Recommended feed rate) Multi- Function ; Recommended D.O.C.: 0.118" or less for ROMU12, 0.158" or less for ROMU16 Corner R Shape During Processing with MRW (See Fig.1) Y (Gap between insert corner-R) B all-nose Radius Other Applications Insert D.O.C.
