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 rs/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. D.O.C. Conversion Factor for Feed Per Tooth (Recommended) (Max.) 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" ROMU12 Type 0.118" or less 0.236" 2.1 1.5 1.1 1.0 (Standard) - ROMU16 Type 0.158" or less 0.315" 2.4 1.7 1.3 1.1 1.0 (Standard) Calculation Example (ROMU12, Carbon Steel, GM Chipbreaker, D.O.C. = 0.039") fz = 0.008 ipt X 1.5 fz = 0.012 ipt (Standard value for carbon steel and GM chipbreaker) (Conversion factor for ROMU12 type, D.O.C. = 0.039") (Recommended feed rate) Recommended D.O.C.: 0.118" or less for ROMU12, 0.158" or less for ROMU16 Y (Gap between insert corner-R) Corner R Shape During Processing with MRW (See Fig.1) Insert D.O.C.

(X), there is a gap (Y) between the workpiece corner and insert corner R (re). The above figure is an estimation. There is a ±0.008" variation depending on the cutting conditions. 11 n KmirFRri U I \J IxJULlIvD
