Week 9 - Attachment Feature Creation - Challenge 1

AIM:

To create the rib for the Centre console coin holder considering the design rules mentioned in the video.

Ribs:

It is used to increase the strength of the molded part.
It is mean to provide the economical stiffness and strength in molded parts without increasing overall wall thickness.
And also providing alignment in mating parts.
It will be act as a guide for mechanism.
If the thickness of the rib gets high, then the sink mark and in turn cosmetic problems on the opposite side of the wall.
And it will locate the components of an assembly.

PROCEDURE:

On that extruded surface, the thickness will be given using thickness option upto 1mm.
Then for that rib the draft angle must be minimum of 0.5 degree per side.
In that rib the bottom will ticker and top it will be thinner.
After that the thickness of the rib wil be reduced upto 0.75mm.
Then the draft must be provided in all the 4 phases.
It will allows the rib to release from the mould.
The fillet has to be provided at the base of the rib.
It can give upto 0.25 mm, sometimes the fillet radius can give upto 0.5mm if the thickness of the rib is high.
And then by taking the intersection definition of the whole part and creating the tritangential circle inbetween the rib and the base surface.
The rib root thickness should not crocc the 30% factor.

Then the sketch of the First rib will be offseted upto 5mm.
That offsetted line will be extruded, pretty much the same operation that was done on first rib.
Then the body will be provided to extruded surface.

Tree structure:

RESULT:

The rib for the Centre console coin holder considering the design rules mentioned in the video.
