High Speed Machining

[RICKY J]

Hi there we just got mastercam x9 at our shop and ive been interested in using dynamic milling for a while .  I don't know where to start with speeds and feeds for high speed machining.  We cut mostly tool steels 4140, a-2, d-2 any help with speeds and feeds would be appreciated.  We use YG-1 V7 variable helix endmills at the moment .

 

 

Thanks

Just set a 5-10% stepover and refer to feed speed wizard app. Works like a charm
