Week 8 - Challenge 2 - Base Bracket Design

Aim - We will Create a Base Bracket plastic component by the given class A surface and after that we will do draft analysis on this component.

Draft analysis - The draft analysis command anable you to detect if the the part you drafted will be easily removed.This type of analysis is performed based on colour ranges identifying zones on the analyzedelement where he deviation from the draft direction at any point ,corresponds to specified values. Most parts or applications require a minimum of half to one degree is widely accepted as per the norms.

Steps for draft analysis on base bracket model

1. First we have to check the connectivity of the class Asurface. Wewill check o join comand and we will see how it will connected for just ensure that no surface gap between the surfaces and by the extracting of given class A surface we can visually check the connectivity of the base bracket model.

2.Create an axis system at big hole.

3.Then we will decide the component ejection and we will set dummy tooling axis is the line along which core and cavity will open.

4. After that we will create actual tooling axis by the helpof bisecting method. Now find the lines lying approximately parrel to dummy tooling axis.These should be the lines along which draft angle is provided.Select two point on the intersection line and then obtain the line as shown in gien image

5. Then we wiil create new line by the help selecting bisecting option in line creation dialogue box and this will be the actual tooling axis for this base bracket model.

6. So now we arein final stage of draft analysis but for draft analysis we have to follow some steps, click on compassicon,drag it to the tooling axis and align it with the tooling axis. After that we have to click in option of customize view parameter mode and select the material option and then we wll click on the base brcket surface.

Next we will create B and C surface by using help of given class A surface

1. we will create two rib surface offsetting the same to the thickness of the component.

2. Now we will create base surface.

3.After that we will go for trimming operation for carried out to get the required class B surface.

4.Now we will create C surface by the help of sweep command
