Reading

understanding: SolidWorks On-line Tutorial – Lesson 1: Parts Introduction to SolidWorks Part generation Creation of U-joint Parts: Bracket, crank-arm, crank-knob, spider, short pin, long pin, female and

male yokes Utilize: sketch elements, geometric relations, and dimensions, extrusions, cuts, fillets,

chamfers, and revolves

Lab problems

1. SolidWorks On-line Tutorial – Lesson 1: Parts 10 points Complete the SolidWorks tutorial on Parts to get familiar with the techniques used to generate

part models. Open SolidWorks

Goto Help Menu � On-line Tutorial � Lesson 1

Show your finished part to an RTA/instructor for approval. lab demo approval:

2. Create U-joint Parts: Bracket.sldprt 20 points lab demo approval:



Create sketch 1 on Right Plane:

Create Boss-extrude on sketch 1: Mid plane extrusion, length = 1.50”



After boss-extrude:

Shell part: Select the 4 faces shown below to shell, distance = 0.250”

After Shell:

1

2

3

4



Create Fillet 1: Fillet the 3 selected edges, radius = 0.125”

After Fillet 1:



Create Fillet 2: Fillet 3 selected edges, radius = 0.375”

After Fillet 2:



Create Sketch 2 on top face of bracket:

Cut-Extrude 1: Cut sketch 2, up to next

Done.



3. Create U-joint Parts: Crank-arm.sldprt 10 points lab demo approval:

Create sketch 1 on Front Plane:

Extrude sketch 1: Blind, distance = 0.750”



Create sketch 2 on top face of part:

Cut-Extrude: Cut sketch 2, through all

After cut:




Cut-Extrude 2: Cut sketch 3, through all

Done.



4. Create U-joint Parts: Crank-knob.sldprt 10 points lab demo approval:

Create sketch 1 on Front Plane: (don’t forget to include centerline)



Base-Revolve: Revolve sketch 1, 360°

Done.

5. Create U-joint Parts: Crank-shaft.sldprt 20 points lab demo approval:



Create sketch 1 on Top Plane:

Base-Extrude 1: Extrude sketch 1, blind, distance = 1.500”

Insert reference geometry, Axis: Insert vertical axis through center of cylinder




Boss-Extrude 1: Extrude sketch 2, distance = 0.625”, Merge result



After extrude:


Cut-Extrude 1 Cut sketch 3, blind, distance = 0.500”



After cut:

Fillet 1: Create fillet 1 on selected edge, radius = 0.1875”

After Fillet 1:



Fillet 2: Create Fillet 2 on selected edge, radius = 0.1875”

After Fillet 2:



Create sketch 4 on inside flat face of bottom cut-out of part:

Cut-Extrude 2: Cut sketch 4, through all

After cut:




Cut-Extrude: Cut sketch 5, blind, distance = 0.250”



Create chamfer on selected edge: Distance = 0.03125”, Angle = 45°

Done.

6. Create U-joint Parts: Yoke-female.sldprt 20 points lab demo approval:



Create sketch 1 on Top Plane

Extrude 1: Extrude sketch 1, distance = 1.875”



After extrude:




Cut-Extrude1: Cut sketch 2, Two directions, through all



After cut:

Create sketch 3 on Right Plane:

Cut-Extrude: Cut sketch 3, two directions, thru all

1.150”



After cut:

Fillet 1: Create fillet on selected edges, radius = 0.0315”, with Tangent propagation

After fillet:




Cut-Extrude: Cut sketch 4, two directions, through all



After cut:


Cut-Extrude: Cut sketch 5, through all



Insert reference geometry � axis though center of part:

Done.

7. Create U-joint Parts: Yoke-male.sldprt 20 points lab demo approval:

Follow same steps as used to generate Yoke-female.sldprt up to and including Fillet 1:



Create new sketch on top face of part:

Boss-Extrude: Extrude sketch, distance = 0.750”, Merge result



Chamfer: Create Chamfer on selected face, distance = 0.050”, angle = 60°

Insert reference geometry � axis along vertical axis of part



Create sketch on top face of part:

Cut-Extrude: Cut sketch, blind, distance = 0.500”

Done.



8. Create U-joint Parts: Spider.sldprt 10 points lab demo approval:


Base-Extrude: Extrude sketch 1, distance = 0.800”



Create new sketch on side face of part:

Cut-Extrude: Cut sketch, through all

Done.

9. Create U-joint Parts: pin.sldprt 20 points lab demo approval:




Base-Extrude: Extrude sketch 1, blind, distance = 1.500”



Click on ConfigurationManager tab that is on top of FeatureManager Design Tree:

Right-click on Default configuration � Properties Rename configuration name and description as shown



Add new configuration to file: Right-click at top of ConfigurationManager � Add Configuration

Provide name and description for configuration:



Go back to FeatureManager Design Tree Right-click on Base-Extrude Feature � Edit Feature

Modify extrude distance, distance = 0.500” In configuration tab in feature definition, select to apply this change to “This configuration” (short).



After feature modification:

Go back to ConfigurationManager. Right click � Show configuration for Long and Short pins to confirm proper configurations created

Done.
