Level
3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed. Method
is to relate the level of PO with the number of hours devoted to the COs
which address the given PO. If >40% of classroom sessions addressing a
particular PO, it is considered that PO is addressed at Level 3 If 25 to 40% of
classroom sessions addressing a particular PO, it is considered that PO is
addressed at Level 2 If 5 to 25% of classroom sessions addressing a
particular PO, it is considered that PO is addressed at Level 1 If < 5% of
classroom sessions addressing a particular PO, it is considered that PO is
considered not-addressed. |

GENERAL
INSTRUCTION IN WORK SHOP
1.
Every student should obtain a set of instruction sheets entitled
manufacturing processes Laboratory.
2.
For reasons of safety, every student must come to the laboratory in
shoes. it is unsafe for the students to come to the laboratory wearing garments

Instruments and tools will be issued from the tool room. Every student
must produce his identity card for the purpose. Tools, etc. must be returned to
the tool room on the same day.
5.
The student should take the permission of the Lab Staff / Tutor before
handling any machine.
6.
The student should not lean on the machine when it is working.
7.

be put off 10 minutes before the end of laboratory session to allow the
students to return the tools.
8.
Students are required to clear off the chips from the machine and
lubricate the guides etc. at the end of the
session.
9.
Laboratory reports should be submitted on blue Book.
10.
