Ex. No. 15 EXERCISE ON REVOLVE
Date:
AIM: To model the given object using the Revolve feature as per the dimensions given.
Description of Revolve Feature:
Command Manager: Features > Revolved Boss/Base
Menu: Insert > Boss/Base > Revolve
Toolbar: Features > Revolved Boss/Base.
Using this tool, the sketch is revolved about the revolution axis. The revolution a xis could be an
axis, an entity of the sketch, or an edge of another feature to create the revolved feature. Note that
whether you use a centerline or an edge to revolve the sketch, the sketch should be drawn on one
side of the centerline or the edge.After drawing the sketch, as you choose this tool, you will notice
that the sketching environment is closed and the part modeling environment is invoked. Similar to
extruding the sketches, the resulting feature can be a solid feature or a thin feature, depending on
the sketch and the options selected to be revolved. If the sketch is closed, it can be converted into a
solid feature or a thin feature. However, if the sketch is open, it can be converted only into a thin
feature.

After you have completed drawing and dimensioning the closed sketch and converted it into
fully defined sketch, choose the Revolved Boss/Base button from the Features toolbar. You

Ex. No. 16 EXERCISE ON RIB
Date:
AIM:
To model the given object and construct rib portion in it.
Description of RIB Feature:
Command Manager: Features > Rib
Menu: Insert > Features > Rib
Toolbar: Features > Rib
Ribs are defined as the thin walled structures that are used to increase the strength of the entire structure
of the component, so that it does not fail under an increased load. In Solid Works, the ribs are created
using an open sketch as well as a closed sketch. To create a rib feature, invoke the Rib Property
Manager and select the plane on which you need to draw the sketch for creating the rib feature. Draw
the sketch and exit the sketching environment. Specify the rib parameters in the Rib Property
Manager and view the detailed preview using the Detailed Preview button. The Rib tool is invoked by
choosing the Rib button from the Features
Command Manager or by choosing Insert > Features > Rib from the menu bar.
After invoking the Rib tool, draw the sketch and exit the sketching environment.

Ex. No. 18 3D MODELING - FLANGE COUPLING
Date:
Aim : To create the models of the components for the FLANGE COUPLING and assemble these
components together, as shown below. Save this assembly model as Flange Coupling.asm. By using
the SolidWorks software.
Application :
This type of coupling is a protective type flanged coupling, the bolt heads and nuts are shielded by a
peripheral protrusion, called „shroud‟, on each flange is shown in fig.5. Alignment of the two shafts is
independent of the bolts and is ensured by the provision of a turned projection, called „spigot‟, on the
flat face of the one of the flanges which fits into a corresponding recess, called „socket‟, in the other
flange. The length of the spigot projection is kept slightly less than the depth of the socket. The socket
and spigot are turned to give a push fit for accurate alignment of the two shafts. The bolt holes ar
drilled and reamed to give a close running for the bolts in order that the load is taken smoothly
without any impact.
Description:
Each of the flanged bosses is securely keyed to the end of each shaft using a tapered key driven from
inside. While assembling, generally the two flanges are set such that the keys fitted in them are out of
alignment by 90degrees to each other. The two flanges are bolted together by a number of bolts and
nuts. Power is transmitted from one
other through bolts.
RESULT:
The given Machine Component is modeled is modeled using SOLID WORKS software.

Ex. No. 19 3D MODELING UNIVERSAL COUPLING
Date:
Aim : To create the models of the components for the UNIVERSAL COUPLING and assemble these
components together, as shown below. Save this assembly model as UNIVERSAL COUPLING .asm. By
using the SolidWorks software.
Application :
It is a rigid coupling that connects two shafts, whose axes intersect if extended. It consists of two forks
which are keyed to the shafts. The two forks are pin joined to a central block, which has two arms at right
angle to each other in the form of a cross. The angle between the shafts may be varied even while the
shafts are rotating.
Description:
Figure shows the details of universal coupling. The forks 2 are mounted at the ends of two shafts 1,
making use of sunk keys 6. The central block 3, having two arms at right angle to each other, is placed
between the forks and connected to both of them by using pins 4 and collars 5. A taper pin (not shown) is
used to keep the pins 4 in position. During rotation of shafts, the angle between them can be varied. Figure
shows the assembly drawing.
RESULT: The given Machine Component is modeled is modeled using SOLID WORKS software.
