chips? Under what conditions are these chips formed?

c) With the help of neat labelled sketches explain the tool elements and tool angles.

2. Mechanics of metal cutting

a) Differentiate between forces acting in orthogonal cutting and oblique cutting

b) From first principles derive expressions for shear angle and shear strain


COURSE HANDOUT: S5

3. During orthogonal cutting with a single point tool having a 0 degree rake angle, the chip

thickness is measured to be 1.13 mm, the uncut thickness being 0.2 mm. Determine the

shear plane angle and also magnitude of the shear strain.

4. Merchant circle

a) With the help of a neat sketch explain how Merchant’s Circle Diagram is plotted

and what is its uses

5. During orthogonal cutting test, the observations made are as follows: the uncut chip

thickness =0.25 mm; measured chip thickness= 1.2 mm; width of cut = 2.5 mm; rake

angle = 0 degrees; cutting force = 900 N ; normal force = 810 N. Calculate the mean

shear strength of the work material. Also estimate the coefficient of friction between the

tool and the chip

6. The following observations were made during an orthogonal cutting operation: rake angle

=10 degrees; co-efficient of friction = 0.85; chip thickness = 2.5 mm; width of cut = 15

mm; cutting speed = 40 m/min; feed = 1.5 mm/rev; shear strength = 650 N/sq.mm.

Determine the following: chip thickness ratio, shear angle; shearing force, friction angle;

cutting force and power consumed at the cutting tool.

7. Derive expressions for optimum cutting speed for minimum cost and maximum

production rate

8. A cylindrical bar is to be turned. The maximum allowable feed is 0.2 mm/rev and at this

feed rate Taylor’s tool life equation for a tool-work combination is found to be vT 0.25 =

75, where v is the cutting speed in m/min and T is the corresponding tool life in minutes.

The labour cost and overheads is Rs. 10 per minute and the total cost involved in each

regrinding of the tool is Rs. 160. On an average, it takes about 2 minutes to change the

Study: Take minimum three simple products, processes or techniques in the area of

specialisation, study, analyse and present them. The analysis shall be focused on

functionality, strength, material, manufacture/construction, quality, reliability, aesthetics,

ergonomics, safety, maintenance, handling, sustainability, cost etc. whichever are applicable.

Each student in the group has to present individually; choosing different products, processes

or techniques.

Design: The project team shall identify an innovative product, process or technology and

proceed with detailed design. At the end, the team has to document it properly and present

and defend it.

The design is expected to concentrate on functionality, design for strength is not expected.

Note: The one hour/week allotted for tutorial shall be used for discussions and presentations.

The project team (not exceeding four) can be students from different branches, if the design

problem is multidisciplinary.
