Week 8 - Challenge 4 - Coin Holder Design

Aim:-

• To create a coin holder plastic component through the given Class A surface and performing the draft analysis on the model.

Objective:-

• To ensure proper tree structure.
• To see overview of the model.
• Geometrical set having proper name.
• Total sketch should be in iso-constraned.
• Thickness of the component is 2.5mm.
• Used closed surface tool at the end.
• Publish Class A,B&C surface.

 Procedure:-

Class A surface:

• Import the Class A surface in catia.

• Check the boundary of the Class A & check the boundary surface is properly closed.

Class B surface:

• Thickness of the component is 2.5 mm and create B surface by using Class A surface of an offset of 2.5mm.
• First we create a side wall and extract it and then by using trim operation we create a final box as shown below known as 'side wall'.

• After that we create a base surface ,the surface should be extracted ,untrim ,extrapolate and then offset it. then requierd portion we hold and trim unnecessary surface.

• We create top wall after side wall, as per same procedure. top wall created by using firstly multiple extract tool with no propagation type ,then extrapolate surface and finally offset it with 2.5mm.

• Initial trim gives exact surface which we needed.

• At the final B surface ,we multiple-extract outer flange.

• Gives proper fillet to the surface.

Class C surface:

• By using Class A surface boundary, created side of the wall at 90 degree with the lenght 4mm.

• Final Class C surface.

Trim surfaces:-

• After creation of Class A, Class B& Class C surfaces ,now we trim Class B and Class C surface to form a new thick surface part and then joined the trimmed surface with Class A surface to form the final required shape.

Closed surface:-

• Now using closed surface option from the part workbench, form a solid body from surface body.

Draft analysis:-

• To perform this operation the object should be in the material mode.
• Conduct the draft analysis on the final surface along with the tooling direction.
• Select the axis system along the tooling direction and select the running point to measure the draft.
• Swich on the colour scale for displaying draft result.

Publication:-

• CLASS A SURFACE.

Tree diagram:-

Conclusion:-

• By using Class A surface, we created coin holder plastic component with draft analysis.
