Week 8 - Challenge 3 - Switch Bezel Design

AIM:

     To design the switch bezel model.

OBJECTIVE:

1.To design switch bezel as per automotive OEM standard.

2.Create class B and C and tooling axis.

3.Converting close surface into the solid inside part workbench and provide the thickness of 2.5mm.

4.Performing draft analysis to verify the creation of the tooling axis and class C surface.

PROCEDURE:

1.A reference point is created along the surface zero and new axis system is created.

2.The X direction along the class A and Y direction along the class A were used to create tooling direction.

3.Tooling axis determines the direction of class C boundary swept with draft direction.

4.When viewing from tooling direction normal all the parts that are drafted should be visible so it gives an rough idea to determine product manufacturing in injection moulding.

5.The next step is to design B surface for the input which is usually the surface where all aspects and support creation are done.

6.The B surface creation is performed using surface operations which is an offset from class A with dimensions proportional to the thickness of the part.

7.The B surface is an extra polated surface compared to A surface and forms the bottom skin of the part.

8.The next step is to form the C surface which is an intermediate surface between A and B and is used to give the closed surface appearance to the design.

9.The C surface is swept using the profile as boundary line of class A which is the Guide curve with subtype.

10.The draft angle for the sweep operation is provided which is 3 degree and surface is swept for length above the thickness of the specified part.

11.The C surface is refined using smooth curve options to remove the complexity and patches along the swept surface.

12.The class A and C surfaces are joined togehter and connexity of surfaces should be less than 0.003 mm and the surfaces are merged.

13.The merged is surface is then trimmed with B surface to form closed surface.

14.The closed surface is then validated to find the irregularirtes along the edges and imperfections along the edges were then connected using opertaions like extrapolate and surface trim.

15.The final part is measured to validate the uniform thickness of the part especially along the fillet edges.

16.The part created has to changed to material mode in display frame.

RESULT:
     Thus the Switch Bezel core is designed sucessfully
