Week 9 - Challenge 1 - Base Bracket Design

Aims-Create the base bracket plastic component through a given class A surface.Below draw the drawing CAD data format.Thickeness of plastic component is 2.5mm.

Procedure-

STEP 1- Check the connectivity of the class A Surface ensure that there is no gap between the component, using join command.We can visually check it or by clicking boundary command.
It has 3 boundaries one outer and two inner circle boundaries.
Therefore first check completed.

Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.
Check visaully which is the best possible tooling axis.
Check all three axis.

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

surface.

Now creating Class B Surface:

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

Then perform Extrapolate inorder to increase the length

Now trim the surfaces to required surfaces

Then Offset the surface inorder to get the required thickness

Similary create the left side rib

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

And now trim inorder to get the required surface

Now fillet the surface to required amount

Now Creating Class C Surface:

EXPLANATION ON BISECTING METHOD:
Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In Bisecting method, bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other. In order to know whether the particular surface is toolable or not we intersect the surface with the respective plane and get a sketch which consist of two lines and with the help of bisecting line option we bisect the line which creates a line at the mid point of the two lines.
