Week 9 - Attachment Feature Creation - Challenge 1

AIM: to create the ribs on the coin holder considering the all design rules.

Tooling axis :

The purpose of tooling axis is to give the direction for core and cavity opens. we have to visually analyse the tooling axis of the surface, and create the dummy tooling axis of the component in the suitable direction.Intersection of the surface is done on the axis which is suitable for the surface.Then the surface lines are created to check the intersection with the tooling axis.Then bisect the compone with the planes. there are so many methods for creating the tooling axis. bisect method is the one of the method to create the tooling axis.

Bisecting Method

For Creating the tooling axis of the component the surface lines are intersect with the dummy tooling axis. The surafce lines of the surface which called boundary is extracted from the surface.The lines from the draft area is created which is parallel to the tooling axis by point to point methodThose two draft surface lines are bisect with the dummy tooling axis.Then the final output of the bisecting lines is tooling axis of the component.

Creation of ribs on the coin holder:

for the ribs first we need to know the all design rules of ribs and understand the consept and design the ribs on the coin holder.

for that we need extract the base. and then draw the sketch for rib.

then extrude the rib using extrude command for 12.5mm(h= 5t)

then thick the extrude for 1mm(t=0.4*thickness of component)

then give the draft to the ribe for0.5 degree and give the fillet to it for0.25mm(as per the design rules of ribs)

then checking the root thickness for that we need to create the circle which touches the all three faces

fiinal component

intersection

Result:

The ribs for the coin holder has been screated as per the design rules.
