In metal cutting, which method involves the cutting edge remaining at 90 degrees to the direction of feed?
- Orthogonal machining
- Orthogonal cutting (correct)
- Oblique machining
- Oblique cutting
What is the characteristic of the chip flow in oblique cutting?
What is the characteristic of the chip flow in oblique cutting?
- Normal to the cutting edge
- At an angle to the normal to the cutting edge (correct)
- Parallel to the tool face
- At an angle to the direction of feed
Why does orthogonal cutting result in a smaller shear force per unit area compared to oblique cutting?
Why does orthogonal cutting result in a smaller shear force per unit area compared to oblique cutting?
- The acute angle of the cutting edge
- Because of the larger area on which shear force acts (correct)
- Due to the smaller size of the workpiece
- Because of two perpendicular components of cutting forces
