Week 8 - Challenge 2 - Switch Bezel Design

Create the Switch Bezel Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Take the Thickness of the component to be 2.5 mm

• Screenshots of the Draft analysis report for both the given Class-A surface and the final plastic component.

To Do Drafting Axis For both Class A surface and Final component Following steps has follow:

1.Creating tool axis .

• To create the tooling axis, we need the proper orientation or view that gives the correct features and draft available in the component.
• So here the component view from the Z direction gives the proper view for the tool to see the features present in the geometry.
• Now i Extracted the base surface.

• Center point is created by using the on surface at zero.
• On that point the axis system is created.

• Take an intersection on the YZ plane to get a boundary line.
• Made a dummy axis line to form a tooling axis by a bisecting two lines.

• After that, I switched the surface and made a sketch on the XZ plane.

  Using the axis center point, a line is drawn in sketch mode and it is constrained at the angle of 4 degrees.

By intersecting both the line so that i get a tooling Axis.

By using this Tooling i done Draft analysis to the Class A Surface.

Drafting Class A Surface:

After Completion of Draft Analysis So we will move forward create the B surface.

Cretaing the B Surface.

1. Base :

• Extract the surface
• Untrim the surface
• Extrapolate it
• Offset it by 2.5mm to the downward.

2. Side Walls:

• Extract the three walls separately
• Un-trim the surface of three extracts
• Extrapolate them

• Trim them with each other.
• Offset the given surface by 2.5mm to the outward direction.

3. Bezel rest surface

• Extract it
• Un-trim the surface
• Extrapolate it

• Offsetted by 2.5mm to the downwards.

So we get all the surface we required then trin all surface so we get calss B surface

Now we have check the rediues from the class and give fillets to edges then we get results like below image.

Now this is our B surface

Cretaing the C Surface.

For Creating of C surfcae we need A surrface.

• Extract the boundaries of the Class A surface by using multiple extracts and make them into smooth curves.

• Sweep the boundaries with the help of tooling axis and give 3 degree draft in outward direction.

Now we have join with Class A surface

Now we will trim with B surface

Now we have check the our switch bezel fully closed or not by using boundray command.

finally our switch bezel is obatained.

Creating a solid body by using a closed surface :

To create soild body firstly switch to part body work bench and use close surface command to soildify the surfasce body.

Now we have perform the Drafy analysis on part body
