Week 9 - Challenge 1 - Base Bracket Design

AIM:

To 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 model.

REPORT ON DRAFT ANALYSIS AND CREATION OF CLOSED SURFACE:

Given Class A Surface:

STEP 1: Check the connectivity of the Class A Surface

Ensure that there is no gap between the component, using the join command.

We can visually check it or by clicking the boundary command.

It has 3 boundaries one outer and two inner circle boundaries.

Therefore, first check was completed.

STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mold opens or the cavity opens.

Check visually which is the best possible tooling axis.

Check all three axes.

Along x it is possible but expensive and y is not possible.

z is the best possible tooling axis.

Creating a Tooling axis along z:

Therefore, the main tooling axis is along the z-axis.

DRAFT ANALYSIS:

Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.

Then after opening the draft analysis toolbox go for the compass and place the compass aligned to the

tooling axis and click on the lock symbol after aligning and further click on the surface.

Now creating Class B Surface:

Initially extracting the right side rib using the extract option from Class A surface.

Then perform Extrapolate in order to increase the length

Now trim the surfaces to the required surfaces

Then Offset the surface in order to get the required thickness

Similarly, create the left-side rib

Now Similarly get the slanted as well as the flat surface and offset it to the desired value

And now trim in order to get the required surface

Now fillet the surface to the required amount

CREATION OF CLASS C SURFACR

Class c surface is created by sweep option

Initially the reference boundry has been taken from the class A surface and also the circular cut ,

And using sweep comand called draft propagetion, the boundry propagetes along the tooling direction

which exceeds the class B surface

now the class A and class C are joined using join command

CREATION CLOSED SURFACE:

Now the three surfaces are joined as a one closed surface by using the trim command.

CREATION OF SURFACE TO PART:

Now the surface componet has been changed to the part model by using closed surface command in part

workbench.
