Week 8 - Challenge 4 - Bumper

Create the Bumper 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. 

Take the Thickness of the component to be 3 mm

• Report
• A detailed report should be done explaining the draft analysis and the tooling axis creation. 
• An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method.

for the tooling axis, we have created the yz plane line at some draft angle after that we convert that line into the line by using the line command that line pass from that line. on both sides, we created the line, and after that by using the bisecting line we drew one line. which is parallel to those lines

the same process is done along the xz axis and after that, we draw the lines which bisect each other and get our tooling axis name 

in the above diagram, I have mentioned all the details for the tooling axis line and all the constraints for the tooling axis 

tooling axis is that axis about which our draft analysis is done 

with the help of that axis, we will do our draft analysis 

and the draft is defined as the angle which helps us to remove the part from the mold very easily after the cooling or shrinkage of the part is inside the mold 

DRAFT 

It is the angle given to the part in the mold which helps us to remove the part from the mold in a very simple way. The maximum draft will be 3 degrees, achieving the draft at 0.5 degrees is very costly because the machining process for this is very difficult 

after the cooling of the part inside the mold, the part will shrink and tends to stick inside it, so here the draft helps us to remove that part from the mold

for the base bracket, we analyze that at the different positions the value of the draft varies from the previous value  which tells us how for the irregular shapes the value of the draft will be different from the last value 

The draft is of many types but the main draft is where the draft is given to the core side after the injection of the molten state material inside t the core tends to make the part shape with the help of the cavity. 

In the end, I am going to attach some pictures of the base bracket draft analysis where we can find out that the draft is different at the different positions
