Can somebody help me, on how to calculate the right feedrate in mm pr. min?
I know it is only a guide number.
I have a 2 flute end mill at 3 mm.
I run my router at 15000 rpm
Cutting depth is 0.1mm
I`m cutting hard alumimium.
My max feedrate is 1000 mm/min.
The table i use for chip load says 0.05 for hard aluminium.
Router is 2 HP, 3500 - 30000 rpm
From the sound of the cutting, the ideal feedrate is around 300 mm/min. But my calculations says 1500 mm/min.
