Week 11 - Final project

AIM

To create a door interior part from the inputs of class A surface along with master section by following the design rules followed in tier 1 and OEM industries in catia v5

SOFTWARE USED

CATIA V5

OBJECTIVES

• Create a sketch by using Positioned sketch
• All the should be sketches should be Iso-Constrained
• Ensured Proper Tree Structure
• Geometrical sets should having a proper name based on the sketches present inside of it
• Create thickened part using master section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
• Creating of Draft analysis & Tooling analysis
• Creation of parting lines and check tooling feasibility

INPUT OF CLASS A SURFACE

          

Since the input class A surface is containing four different parts(class A). So class b and c for all the surface has been created in separate catpart. Also performing draft analysis and tooling axis separately. finally all the surface have assembled together in  one catproduct

CREATION OF TOOLING AXIS 

DRAFT ANLAYSIS

   Draft analysis in catia is a command that is used to detect if the part you drafted will be easily removed from the mold. it is performed based on color ranges identifying zones on the analyzed element.

   Most of the industries is using minimum draft angle is 3 degree

PROCEDURE

• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.
• After analyzing the above model the best tooling axis is y direction.
• After that offsetting A Surface feature and create B surface.
• then Create C surface anf then Trim all the parts.
• them make a solid body 
• after that create B surface Features (dog house,heat stake,push pin,locators)
• then assemble all the parts

Conclusion

    Creation of the car interior door trim is designed using the given class A surface as the input and Class B and C surface created with the help of Class A surface. By using the given master section attachment features I.e. Heat stakes, Flanges, Dog House and Push Clips are created using the design rules. The draft analysis has been performed to analysis the draft of the component to manufacture easily applying draft to the surface by 3 degree and 0.5 degree to the attachment features. With all data and report we can conclude that draft analysis is very important to design any plastic component to mold the plastic easily. The analysis will verify that all surfaces are favorable for being pulled from a cavity. It may also highlight or given insight to defect areas.
