GENERAL TECHNICAL INFORMATION PARTING AND GROOVING SELECTING INSERTS To match the correct insert and cutting condition the following variables must be considered. Width of cut (width of insert) Chipbreaker style Lead angle Corner radii Carbide grade Width of Cut (WOC) and Depth of Cut (DOC) To select the proper width and depth of cut the application must be considered. The ratio DOC 8 x WOC can be used when cutting steel. For example the maximum DOC for a 3mm wide insert is 0.945" for parting a 1.190" diameter bar. Neutral inserts with a 0 lead angle provide the maximum rigidity. Lead Angle Use inserts with a lead angle to minimize pips or burrs. Inserts are available with either R or L hand design. Increasing the lead angle reduces the pips or burrs but will also produce a poor surface finish and short tool life. Neutral inserts are recommended when a pip burr is acceptable. INSERT SUPPORT Integral shank tool holders offer the best rigidity A self clamp holder is only recommended for radial machining A screw clamp holder is recommended for axial and radial machining. BLADE OR HOLDER SIZE: To minimize vibration and deflection choose: Blade or tool holder with the smallest possible overhang (Tmax). Tool holder with the maximum shank size (H). Blade height that is larger than Tmax. Blade or tool holder with the maximum blade width (largest possible insert seat size). 1348
