End Mills. The Essential Beginners Guide.

End Mill Cut Varieties: Centre-cutting end mills are those that can be plunged straight down into the material. They can mill, and they can drill. (They have cutting edges on the end face and the sides) These are usually the 2 flutes or 3 flute endmills, and occasionally you can find some 4 flutes that are centre cutting as well.

Milling Parameters

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.
