CARBIDEEND-MILLS “ae” value max 0.2xD - “T” value max 0.1xD. 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. G2 With lower CNC dynamic speed, use the same cutting conditions or reduce the cutting speed Vc. MDTA With higher CNC dynamic speed, reduce the “T” value by approximately -30 -50% and apply the maximum available cutting speed Vc.
