Check machine speed setting before operating. Make sure cutter meets or exceeds speed rating of tool. In the
diagram Fig.3.4 a concrete example of choosing a speed in function to the diameter of the utensil, and the most
opportune peripheral speed for the type of material to be worked on.
Cutter speed formula:
ν
= (D×
π
×N) / (60×1000)
D: Tool diameter (mm)
N: Tool spindle speed (rpm)
Fig. 3.4
Fig.3.4.1
The cutting speed range m/sec (lower and upper limits) is selected
according to the tool diameter (mm) D (left vertical axis in the
above chart) and the tool spindle speed N min
-1
(bottom horizontal
axis in the above chart) to avoid the risk of kickback or tool damage
respectively.
