Because there are 10000 different kinds of materials shall i show you the most used.
There a 2 things you must know.
1) Cutting speed.
2) Turning speed. ( for drilling machine )
With the cutting speed you can calculate the turning speed.
Example. You use normal steel. That has a cutting speed of 20. And you use a drill with a diameter of 6 mm.
Turning speed = ( Cutting speed X 1000 ) / ( Diameter X PI )
Turning speed = ( 20 X 1000) / ( 6 X 3.1416 )
Turning speed = 1061 rotations / minute
Material Cutter speed
Stainless Steel 6 - 10
Brass 50 - 100
Copper 25 - 35
Aluminum Hard 50 - 120
Aluminum Soft 30 - 50
Synthetic soft 50 - 100
Synthetic hard 15 - 35
The speeds i gave you are old. New types of drills have different and much higher cutting speeds, but these values what i gave you are for hobby people and not for industrial tools.
