Week 12- Final project

Based on the knowledge that has been gained by taking the Plastic Design Course by CATIA V5 I have develped Class B Surgaces, Class C Surfaces, tooling axis for every single part, also, I found a strategy to assemble the four seperate parts into one part design by creating engineering features such as Heat Stakes, Ribs, Dog Houses and Flanges.

Armrest Part:

a.

Class A Improvement:

First I have found that Class A that been givin has open boundries.

Class B is created by offseting Improved Class A by 2.5 mm as per the master section.

Class C is created by sweeping Improved Class A Surface and it has been trimed with Class B Surface.

In oder to Join the Armrest body with the other bodies, I created 4 Flanges seperatly with counter holes, Flanges are different based on the engineering features will be held. Then these flanges are assembled to the main body (Armrest) by unitrim feature.

Each Flange was created by extracting surface from Class C Surface aidded by Generative Surface. then I applied close surface feature to creat the flange body, Drafted by 0.5 deg, Filletted. Also it is important to mention that the counter holes were created by iso constrained, positioned sketches and then paded it and drafted before it was removed from the main flange.

Drafting Analysis:

By applying drafting analysis at 2.9 Deg, we can see must bodies are been cleared. As Green set at 2.9 degree, blues is Zero and less than Zero it is red colored.

2- Lower Substrate:

A- Class A Surface was givin is cheke and found out it is perfectly closed boundries,no further action to be taken.

In oder to Join the Lower Sustrate with the other bodies, I will be useing the Lower Subtsrate as the main body where other can be installed accoring to it. All connecting engineering features are created attched to this body while flanges will be conecting this main body to other bodies. two dog houses are created, 8 heat stakes and 2 4 way lockers are created and attached to this body.
