The use of end mill with diameter 30-40% smaller than the width of the slot is recommended. The cutting conditions are based on CNC programming with medium dynamic speed. HSS With lower CNC dynamic speed, use the same cutting conditions or reduce the cutting speed Vc. DRILLS With higher CNC dynamic speed, reduce the “T” value by approximately -30 -50% and apply the maximum available cutting speed Vc. ae R1 Cutter radiusR2Half of slot width LFTASUTA HSS-HSS/CO T Programming width of cut ae Actual width of cut Y (+) Y X (+) CARBIDE T END-MILLS G2 MDTA HF VH/UP MEF ALU MEX/MH UH/MH HSS END-MILLS CARBIDE BURRS PARAMETERS SUGGESTED WITH HIGH POWER MILLING CHUCK AND STABLE MACHINING CONDITION 373 R2 R1
