USE OF A SHEET METAL TO BUILD UP A MUG(PART 3 & LAST PART)

Calculation:

We had to make a mug where diameter is height of the body 4” meanwhile the length of the handle is 7”.

i) Circumference:

For dia = 4”xπ + allowance

Horizontal = 4”×π + (1/4” +1/4” clearance)

= 12.56 + (1/2” clearance)

= 13.5”

For vertical = height + clearance

= 4” + (1/4” + 1/4”)

=4.5”

Handle length = 7” + (1/4” + 1/4” clearance)

= 7.5”

The upper part of the handle = 1” + (1/4” + 1/4” clearance)

=1.5”

Operation for making a mug:

First we cut the sheet from sheet plane. It is wide. It was cut by hand share. Making clearance by a divider all around the taken sheet. We took the sheet for bonding the extra portion of the sheet. We made the sheet round in a definite pipe. We made the round sheet with ahiset by straining a metal.

We cut a sheet in dia too lower part of a mug. After bonding it to connect with upper part of the mug. The extra portion is connected by striking with upper part of the mug. Then the extra portion is connected by striking it with hammer.

Then we made a hole in the mug. In the hole, we joint resist to make the mug strong.

Performance:

The job in workshop at sheet metal helps us to aware about making a simple mug in broad sense. But in practice we come to know about the use of different hand tools & mechanical tools in sheet metal shop. The most important thing is that we have broad idea about the sheet metal shop in manufacturing the world.

Conclusion:

One of the characteristics of the skilled worker is the way in which he selects & uses the tools of his trade. It is essential to know how to select & proper use both the hand 7 mechanical tools of the sheet metal trade. Therefore, a little work in workshop that we have had an important significances. I think all B.Sc. Engineers must have a fair idea about the manufacturing world to take the first step toward becoming a successful sheet metal craftsman.
