Fig. 1: Forces and torques at the machining and clamping point
F = main cutting force on the radially acting tool
s
F = cutting force on the axially acting tool (drill bit)
sBo
F = feed force on the axially acting tool
vax
F = total clamping force required (without the effect of turning speed)
spz
F = centrifugal force of the jaws / = loss of clamping force (see clamping
c
force/speed diagram of the individual chuck types)
F = (total) initial clamping force with the chuck stationary
spo
l = distance between machining and clamping points
z
d = machining diameter
z
d = clamping diameter
sp
l = clamping length
