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.

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

• Find a attachment strategy for the door panel complete work.

  Use Push pin with Dog house for Lower substrate – Door panel attachment

  Use heat stakes for part to part attachment

Given Input

              ARM REST

                   LOWER SUBSTRATE

                UPPER SUBSTRATE

                         BOTTOL HOLDER

SURFACE MODELING for ARM REST

• Class B surface has been created by offsetting the surface 2.5mm. Surface that are not offsetting were formed by using multi section command and join them.

• Using the multiple extract commands boundaries of class, A surface were extracted. Class C surface joins class A and Class B surfaces. It is created using the sweep command. Inputs for the sweep were extracted boundary, class a surface angle values and length of the sweep. Due to surface irregularities, it was not possible to make a single sweep. Hence several sweep and multi section were created, and finally they joined together to create a Class C surface.

• After joining the class, A and class C together, the join surface trimmed with class B surface to create a close surface. Some errors showing that’s why we extrapolate the class B surface for correctly trim the class A and C with class C.Go to part workbench insert a body and doing close surface operation create the solid body.

• As given Master section in dialog box. Flanges, dog house, heat stack are created are using Master section.

• Draft Analysis are performed afer attachments are added as per Master section.

SURFACE MODELING for LOWER SUBSTRATE.

• Same steps followed As like DOOR ARM REST

SURFACE MODELING for UPPER SUBSTRATE.

• Same steps followed As like DOOR ARM REST

SURFACE MODELING for BOTTLE HOLDER.

• Same steps followed As like DOOR ARM REST

DOG HOUSE

• Dog house is the attachment feature which helps you to assemble things at certain heights and also resolve the plastic defects.
• There are plenty dog house design which can be used for assembly purpose but we will  be using the one provided to ous by the resources.
• The master section or  the enginnering drawing must be followed for creating the dog house.

PUSH PINS 

• These pins are used for  the assembly purpose .
• These pins are guided into the sheet metal body.
• The pin is assembled over the dog house on one side and other into sheet metal.

CONCLUSION

• The door panel successfully designed by following all design rules used in automotive industry. All the attachment feature are properly placed at different location.
