Feed rate F for tapping
The feed rate for tapping F is calculated from the thread pitch p and the
spindle speed S:
F = p
. S
Units:
F in mm/min
p in mm/1
S in rpm
The feed rate for tapping can be read directly from the diagram below.
Example:
Thread pitch
p = 1 mm/rev
Spindle speed S = 100 rpm
Feed rate for tapping F = 100 mm/min
Thread pitch
p [mm/rev]
Spindle speed
S [rpm]
