Week 9 - Project 1 - Door Applique Design with Engineering Features

AIM- Create the Door Applique Plastic component through the given Class-A surface.

Tooling axis creation
The tooling axis is the direction of drawing a sheet metal where the finished component is easily ejected on a particular direction
and axis. The tooling axis is important for removing the material when finished.

• First Extract the surface then create a point.
• then create a lin in the y direction with desire length.
• give it a graphic appearence and name it a tooling axis.

DRAFT ANALISIS OF CLASS A SURFACE

Creation of Class - B and C surface
extracting the class - A surface without the fillets and then trimming and extrapolating them to join them, and after that offset the
surface to 2.5 mm thickness which forms as the Class - B surface.

Draft Analysis report
When a plastic component is made, we can observe a draft angle given on each side from the base that is lesser than 90 degrees.
This is because in the criteria of making a plastic material the mold should release the material when finished. if the mold surfaces are 90 degrees the material won't release from the mold because of friction due to contraction of material when cooled.

To resolve this problem we CAD engineers maintain a standard rule to design the plastic mold or die's in such a way that there is no problem while ejecting the plastic component. So a minimum of 3 - 10 degrees of draft angle is given to every plastic component while designing.
