IFS Mechanical Engineering (Paper II) Exam old Papers

Will you please provide me the IFS Mechanical Engineering (Paper II) Exam Previous Years Question Papers???

Yes sure, here I am sharing the IFS Mechanical Engineering (Paper II) Exam Previous Years Question Paper:

5. - (a) How do you define the cutting angles of
a single-point tool in liJ International
(LMN) and fii) American (x, y, z) system?
Show them in the form of diagrams. 10

(bJ Which probability distribution is usually
associated with PERT and why? Plot
this distribution and indicate on it the
relevant parameters of PERT. Which
other distribution do you think may be
appropriate for the purpose? 10

(c) (i) Why does the tool wear during
cutting? Enumerate the possible
mechanism of tool .wear.

(ii) A top1 lasted for 45 min before
regrind in a milling operation. The
cutting speed was recommended to
be increased by 50%, but it was
found that now the regrind was
needed after every 20 min on an
average. Can you define Taylor's
tool-life equation valid for this
operation, assuming that there is
no other change in the system? 5+5

(d) Draw a flow chart to find the torque to
be transmitted by a solid steel shaft at a
specified speed. Maximum shear stress
is to be limited to a specified value.
Factor of safety, tensile strength of steel
and other parameters can be assumed
to be given. 10
