GENERAL TECHNICAL INFORMATION PARTING AND GROOVING SELECTING INSERTS INSERT SUPPORT To match the correct insert and cutting condition, the following • Integral shank tool holders offer the best rigidity variables must be considered. A self clamp holder is only recommended for radial machining • Width of cut (width of insert) • A screw clamp holder is recommended for axial and radial • Chipbreaker style machining. • 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. BLADE OR HOLDER SIZE: • Inserts are available with either R or L hand design. • Increasing the lead angle reduces the pips or burrs, but will also produce To minimize vibration and deflection choose: a poor surface finish and short tool life. Neutral inserts are recommended • Blade or tool holder with the smallest possible overhang (Tmax). when a pip/burr is acceptable. • 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).
