Week 12- Final project(Door Trim Panel)
Door trim panel is creation of CAD model considering following inputs as like in OEM and tier1 companies
Class A surface is givin but after applying boundries check, it has been found there is some improvement needed to be actioned to get a closed surface. Nominal thickness is taken from the provided master sections.
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.
1- Armrest Part:
a. Class A Improvement:
First I have found that Class A that been givin has open boundries
Corrected Class A Surface:
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
Final Trim:
Close Body is created from the fully close 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.
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.
Close Body is created from the fully closed surface:
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.
Each engineering feature 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 and champherd. Also it is important to mention that features were created by iso constrained, positioned sketches and then paded it and drafted.
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.
3- Bottle Holder:
A- Class A Surface was givin is checked and found out it is perfectly closed boundries,no further action to be taken.
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.
Final Trim:
Close Body is created from the fully closed surface:
In oder to Join the Map Pocket with the other bodies, I created 3 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 (Map Pocket) 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.
4- Upper Substrate
A- Class A Surface was givin is checked and found out it is perfectly closed boundries,no further action to be taken.
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.
