What are the two basic ways of metal cutting using a single-point cutting tool and a multi-point cutting tool?

What are the two basic ways of metal cutting using a single-point cutting tool and a multi-point cutting tool? Correct Answer “Orthogonal” and “Oblique” cutting

Explanation:

  • During machining, based on the direction of chip flow and orientation of cutting edge, the machining operation is broadly divided into two types.
  • They are as follows:

Orthogonal Cutting

Oblique Cutting

In orthogonal cutting, the cutting edge is perpendicular to the direction of the tool-travel.

In oblique cutting, the angle between the cutting edge and direction of tool-travel is less than 90°.

The chip flow angle is zero.

The chip flow angle is more than zero.

The tool life is less.

Tool life is more.

Two components of forces.

  • Axial (Px)
  • Tangential (Pz)

Three components of forces.

  • Axial (Px)
  • Tangential (Pz)
  • Radial (Pxy)

Poor surface finish.

Good surface finish.

Used in slotting, parting, grooving, pipe cutting.

Used in turning, milling, drilling, grinding.

Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge. Which of the above statements are correct?

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: Inclusion is also about finding different ways of teaching so that classrooms actively involve all children. It also means finding ways to develop friendships, relationships and mutual respect between all children, and between children and teachers in the school. Q: Creativity may mean teachers learning to teach in different ways or designing their lessons so that all children can be involved. R: Inclusive education is about looking at the ways our schools, classrooms, programs and lessons are designed so that all children can participate and learn. S: All children are at all times ready to attend regular schools and classrooms. Their participation is not something that must be earned. Inclusive education is a way of thinking about how to be creative to make our schools a place where all children can participate.
