GN6005 Basic of cutting process

Cutting edge of the tool is ​ (a)   to the direction of tool travel.

• perpendicular
• parallel
• diagonal

Orthogonal cutting is called 2D cutting while oblique cutting is known as ​ (a)   cutting process

• 3D
• 1D
• 4D

In Orthogonal cutting the tool has ​ (a)   cuttings life and in Oblique cutting the tool has a ​ (b)   cuttings life.

• lesser
• higher
• equal
• shorter
• longer
• uneven

In oblique cutting, three components of force are considered, choose the 3 forces involved in it.

• cutting force

• thrust force

• radial force

• tangential force

In Oblique cutting process the cutting angle is ____ than 90 degrees

Organize these options into the right categories

Groups:

(a) Orthogonal Cutting

,

(b) Oblique Cutting

• Cuttings may or may not be longer than the edge of the cut

• tool has a higher cuttings life.

• the surface finish is poor

• tool has lesser cuttings life

• cutting surface finish is good

• cutting angle of the tool makes a right angle to the direction of motion

• Cutting edge is longer than the edge of the cut

• flow of the chip is not perpendicular to the cutting edge
