CARBIDE NOTES:
END-MILLS Down milling CNC programming is required.
“ae” value max 0.2xD - “T” value max 0.1xD.
G2 The use of end mill with diameter 30-40% smaller than the width of the slot is recommended.
MDTA The cutting conditions are based on CNC programming with medium dynamic speed.
HF VH/UP With lower CNC dynamic speed, use the same cutting conditions or reduce the cutting speed Vc.
MEF With higher CNC dynamic speed, reduce the “T” value by approximately -30 -50% and apply the maximum available cutting speed Vc.
