Week 9 - 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  requirement  of the draft angle and at the end perform the  Draft analysis on the  model.

REPORT ON DRAFT ANALYSIS:

Given Class A Surface:

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. Therefore first check completed.

STEP:2

Find  the tooling axis  of the component.  The tooling axis is nothing  but  the mould opens. Check visaully which is the best possible tooling axis. Check all three axis. Along X it 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 Z axis.  Now  perform the draft analysis using the Featured Draft Analysis tool in the tools. Then  after opening the draft analysis tool box go for the compass and place the compass  alinged to tooling axis and chick on the lock symbol after alinging and further click on the 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 surface to required surface 

Then offest the surface inorder 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  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 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. Like X and Y which will be used to create the main tooling axis using the bisecting line option in the command.
