5.3.3 Cutting Forces, Torque, and Power
As shown in Figure 5.18, the drilling forces are decomposed into two main
components that are situated at a distance (d/4) from the drill axis. Each com-
ponent is further decomposed in three directions:
The axial components F
a1
and F
a2
are in the direction of the tool feed
that is parallel ...
