Oblique Cutting
|
The cutting edge of the
tool is perpendicular to the direction of feed motion.
|
The cutting edge of the
tool is inclined to the direction of feed motion.
|
The chip flow angle is
more than zero.
|
|
There are only two
components of force; these components are mutually perpendicular.
|
There are three mutually
perpendicular forces acting while cutting process.
|
The cutting edge is larger
than cutting width.
|
The cutting edge may or
may not be larger than cutting width.
|
Chips are in the form of a
spiral coil.
|
Chip flow is in a sideways
direction.
|
High heat concentration at
cutting region.
|
Less concentration of heat
at cutting region compared to orthogonal cutting.
|
For a given feed and depth
of cutting, the force acts on a small area as compared with oblique cutting,
so tool life is less.
|
Force is acting on a large
area, results in more tool life.
|
Surface finish is poor.
|
Good surface finish
obtained.
|
Used in grooving, parting,
slotting, pipe cutting.
|
Used almost all industrial
cutting, used in drilling, grinding, milling.
