Week 9 - Attachment Feature Creation - Challenge 1

Aim:- The Aim of the project is to create the rib for the Centre console coin holder considering the design rules.

Tooling Axis:-

Here first we will discuss how the tooling axis is created for the give class A surface.

• In the given class A surface the side walls are perpendicular to the base so it will create a problem while open and close of mold.
• so we need to tell the class A surface designer to give some draft angle to the all plains, so that it will not create any problem while manufacturing.
• In the surface the wall are perpendicular so we extracted the base and kept the point at the center of surface.
• At the center point we drawn the line with normalto the surface.
• The line drawn along the center point is the TOOLING AXIS of the surface.

Design of ribs on coin holder :-

Here we kept a point at the center of the coin holder and drawn the sketch by taking the reference as base plain.

Next we extruded the line upto a height of design rule that is 5*t and we give thickness 1mm for the ribs and drafted the ribs at 0.5 degree.

After drafting the ribs we assembly this body with coin holder and we do edge fillet for the ribs of 0.25mm.

This is final design of ribs for coin holder.

We have done draft analysis on ribs and we got 0.5 degree of angle for the ribs.
