Both reaming and tapping are internal
machining processes, why the tapping is
more difficult?
Tapping produces a significant amount of
chips and their removal through the hole being
tapped can be difficult as they can get clogged
(and can cause tap fracture). Control of
processing parameters and use of effective cutting
fluids are thus important.
Describe the difference between up milling
and down milling.
In up milling, the cutter speed
direction is opposite the feed direction; in
down milling, the
