Depth of Cut ap (in) GENERAL TECHNICAL INFORMATION TURNING AND GROOVING CHIPBREAKER STYLE: "T" • The “T” chipbreaker is available for turning and grooving of steel, • Machining range of turning depends on width of inserts. alloy steel and stainless steel • Inserts with “T” style chipbreaker contain a central chipbreaking island for multi-direction chip control Workpiece: SAE 1045 (C45) “T” Type Cutting Speed: Vc=328 - 590 in/min T 0.196 TDT6.00E-0.80 0.157 TDT5.00E-0.80 0.118 TDT4.00E-0.80 0.080 TDT3.00E-0.40 0.040 0.020 0.004 0.008 0.012 0.016 0.020 Feed (IPR) Reduce cutting speed 20 - 30% for internal & face machining TOOL HOLDER OR BLADE SIZE MACHINING DEFINITIONS To minimize risk of vibration and deflection always choose: • Tool holder or blade with the smallest possible overhang. • Tool holder with maximum shank dimension. 90° MOUNTING It’s very important that the insert is mounted at 90° to the center line of the workpiece in order to obtain a perpendicular surface and reduce the risk of vibration. Grooving • Vc - Cutting speed (SFM) .004/3.95 • T - Maximum depth (in) 90°±10´ • f1 - Feed in radial direction (in/rev) Turning • Vc - cutting speed (SFM) • apmax - maximum depth of cut (in) • f2 -feed in lateral direction (in/rev) 1355
