Week 11 - Final project

AIM:-

To create a solid body of Side Door plastic trim including the engineering features using CATIA V5 tool using the given Class A surface and master section and adding thickness to the component

Objective:

• Creation of side door trim panle from given class A surface . Apply thickness to it and use attachment features .
• Creation of flanges and heat stakes from given master sections .
• Creation of various attachment features using industry standards .
• Performing draft analysis and ensuring the features and surfaces clear it .

Creation of Tooling Axis:

• Extract the edges of locators in master section.
• Create a point on the surface.
• Draw lines using point- direction option and rename it as tooling axis.

Creation of Class B Surface:

• Create a geometrical set, name it as Class B surface and extract the surfaces of class A using extract command.
• Offset the surface for 2mm.
• Extrapolate and trim the required surfaces.

Creation of Class C Surface:

• Extract the edges of class A surface with flanges using multiple extract.
• Sweep the extracts with reference surface or draft direction as tooling axis.
• Extrapolate the sweeps to create class C surface.
• Trim the class C surface with class B surface.

Creation of Solid Components:

• In part design workbench, use close surface command on the surface to create solid plastic component.

Creation of B- Side Features (Engineering Features):

Creation of Flanges:

• Create a plane on the master section with 3 points.
• Create a sweep on the edges of the class A surface using extracted edges by multiple extract command.
• Check the sweep by intersecting the master section with plane created.
• Offset the sweep based on the intersect.
• Trim the class A with sweep.
• Use thick surface command to thicken the required surface.
• Sketch holes required for heat stakes.
• Make draft for 0.5⁰ on sides.
• Create edge fillets on the edges.

Creation of Heat Stakes:

• Create a sketch and draw the profile for heat stake.
• In part design workbench, pad the sketch for required height.
• Create ribs for heat stakes.
• Draft and fillet the body of the heat stakes and ribs.
• Union trim the bodies together.
