Week 8 - Challenge 1 - Base Bracket Design

Challenge 1 - Base Bracket Design

AIM:- Create the Base Bracket 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 mode

OBJECTIVE:-

• Creation of Tooling Axis.
• Creation of class B and C surfaces.
• Creating a solid part out of surface modeling.
• Draft Analysis of class A Surface and final plastic component.

CLASS A:- Following Surface is given as the input for the component creation.

Draft Analysis for surface A:

The analysis is done for the 3-degree draft. So as can be seen all the surfaces are more than 3deg.

Creating of Tooling Axis:

• Create an intersection of CLASS A surface with ZX plane and from the intersection create the tooling axis as shown below

Creation of the Class B Surface

• we have to extract faces from the class A surface. and untrim them to obtain the original parent surface.
• This surface is then offset to the required thickness.
• required fillets are given to the surfaces.

Creation of class c:

• For creating this surface we have to extract the boundary of class A.

• Now swept along the draft direction with a 3deg draft.

Final Trims:

Surface A + Surface C

To make sure that there is not any open boundary between class A and Class c, we have used the join option to create the single body. This is done to make sure that the parting line doesn't lie between these two surfaces.

Surface A + Surface B + Surface C

For this, we have trimmed the join of the Surface A and Surface C Surfaces With Surface B.

Draft Analysis:

For this analysis main tooling axis in taken draft reference,

The following results were Obtained:
