Summary: The major difference between orthogonal and oblique cutting is that
in orthogonal cutting, the cutting edge of the tool is perpendicular to the direction of motion
. In oblique cutting the cutting edge makes an angle with the direction of motion.
What is orthogonal cutting used for?
Orthogonal cutting the cutting edge is straight and is
set in a position that is perpendicular to the direction of primary motion
. This allows us to deal with stresses and strains that act in a plane. Oblique cutting the cutting edge is set at an angle. Examples: drilling, milling, broaching, reaming.
How oblique cutting differs from orthogonal cutting?
The main difference between orthogonal and oblique cutting is that in orthogonal cutting,
cutting edge of tool is perpendicular to the direction of motion
but in oblique cutting the cutting edge make an angle with direction of motion. The flow of chip is perpendicular to cutting edge. … The tool has lesser cutting life.
What is an orthogonal cutting operation?
The term “orthogonal cutting” has been coined1 to
cover the case where the cutting tool generates a plane surface parallel to an original plane surface of the material being cut
and is set with its cutting edge perpendicular to the direction of relative motion of tool apd workpiece.
Is another type of cutting in which the cutting edge of cutting tool make a angle other than right angle to the direction of tool motion?
Oblique cutting
is another type of cutting in which the cutting edge of wedge shape cutting tool make a angle except right angle to the direction of tool motion. This will affect the cutting conditions.
Where is oblique cutting used?
Orthogonal cutting Oblique Cutting | 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. |

Which of the following is an example of orthogonal cutting?
Orthogonal Cutting (2-D Cutting): the Cutting edge is (1) straight, (2) parallel to the original plane surface on the workpiece and (3) perpendicular to the direction of cutting. For example Operations:
Lathe cut-off operation, Straight milling
, etc.
What is meant by machinability?
Machinability defines the
ease at which a material (mainly metal) can be cut or shaped while providing a satisfactory surface finish
. A material with good machinability requires little power to cut, produces a smooth surface finish and minimizes wear on the tooling.
Is drilling orthogonal cutting?
orthogonal cutting.
uniform cutting
. …
What are the different parts of single point cutting tool?
- Shank: The main body of the tool is known as shank. …
- Face: The top surface tool on which chips passes after cutting is known as face. …
- Nose or Cutting point: …
- Base: …
- Heel: …
- End cutting edge angle: …
- Side cutting edge angle: …
- Back rake angle:
What is Lee and Shaffer relation?
Lee and Shaffer’s relationship between and is derived on the assumption that: A.
The material being cut behaves like an ideal plastic which does not strain harden
. … As the tip of the tool approaches the stress builds up till it reaches a value high energy to cause plastic deformation.
What is the significance of shear angle?
The shear angle is defined as
the degree of angle that changes at peak frictional force and at the commencement of the experiment
. where b is the uncut chip thickness, (p shear angle, w the cutting width, and the tool-chip friction angle.
What is the process of turning?
The general process of turning involves
rotating a part while
a single-point cutting tool is moved parallel to the axis of rotation. Turning can be done on the external surface of the part as well as the internal surface (the process known as boring).
Why is tool life more in oblique cutting?
Oblique cutting is a type of cuttings in which the cutting tool is at an oblique angle in the direction of the tool’s motion. The chip flow in this cutting is not cutting edge. The tool has a
longer cutting life than orthogonal cutting
.
What is rake angle in cutting tool?
Rake angle is a parameter used in various cutting and machining processes,
describing the angle of the cutting face relative to the work
. … Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side.
