Week 8 - Challenge 3 - Switch Bezel Design

Project Title : SWITCH BEZEL DESIGN

AIM : 

To create the switch bezel plastic component through the given class - A – surface and at the end performing the draft analysis on the model.

OBJECTIVE :

• To ensure proper tree structure is followed.
• Geometrical sets should have a proper name based on the sketch present inside of it.
• All the sketches should be created under geometrical set.
• Use of the closed surface feature to make a solid body from the surface.
• To publish the tooling axis, Class A,B and C surface.

TOOLING AXIS CREATION :

The tooling axis is the direction of drawing a sheet metal where the finished component is easily ejected on a particular direction and axis. The tooling axis is important for removing the material when finished.

         

The tooling axis is created for the given class-A surface.

Creation of tooling Axis (Bisection method) :-

• Extract the base surface of the given Class-A Surface and create the center point of the Extracted surface.
• Then create two sketches on two planes by taking the cross section of the given surface in the particular plane.

          

• Tooling axis created from the two lines using the cross section and also creating one with the help of cross section line of the surface on X plane as bisecting line.

         

• And now by creating another bisecting line using those two plane sketches is the tooling axis for this particular Class-A surface.

          

Creation of Class – B Surface :-

Extracting the Class-A surface without the fillets and then untrim and extrapolating them to join them, and after that offset the surface to 2.5mm thickness which forms as the Class B surface. Given fillets in required area, w.r.t. Class A surface.

         

Creation of Class - C Surface :-

By extracting the boundary of the Class – A surface, the surface required for the class – C is obtained.

Using the smooth curve option, a smooth surface can be obtained by sweeping the line towards the direction of the tooling axis.

          

Joining & trimming all the surfaces together.

          

Draft Analysis on Final Surface :-

• Now drag the red-coloured point on the compass to match the tooling axis which we have created.
• Click on the lock icon under the display command and a point will appear on your screen and tap the point on surface of the Switch Bezel.
• Change the angle from 2 degrees to 3 degrees on draft analysis.2 dialogue box and on draft analysis dialogue box click ok. The below image shows the enlarged draft analysis dialogue box.
• Now go back to lock icon and ok. And see how the object appearance. If is in green colour we can say that the object is fine and we can proceed with that if it is showing in any other colour such as blue or red we have to modify our design.

          

Solid Body :-

• Change to Part workbench.
• Create Body.
• Surface Base Feature – Close Surface – Select last Join.

         

TREE STRUCTURE :

VIEWS OF SWITCH BEZEL AFTER DRAFT ANALYSIS :

• Front View

          

• Back View

         

• Left View

                        

• Right View

                        

• Top View

            

• Bottom View

            

• Isometric View

            

CONCLUSION :

Here I am concluding that the draft analysis on a Switch Bezel has been performed successfully.
