Week 8 - Challenge 3 - Coin Holder Design

AIM: To create the Coin Holder Plastic component through the given Class-A surface.

OBJECTIVE: The objective is to 

begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model. 

• Thickness of the component to be 2.5 mm

PROCEDURE:

1. TOOLING AXIS

The tooling axis is a direction along which the core and cavity tends to move.  Here the tooling axis is created in direction, which is normal to one of the Flat surface of the Coin Holder.

2)CLASS B SURFACE

    As usual B surface is created using standard procedure by extract, un trim, extrapolate and offset commands. B surface of this coin holder is divided as base, side walls, top wall and outer surface. B surfaces of all these sub parts are created and trimmed together to join as single surface.

    The offset distance is kept 2.5mm as component thickness is 2.5mm.

(A) SIDE WALL

(B) BASE

(B) TOP WALL

(C) INITIAL TRIM

(D) OUTER FLANGE

• FINAL CLASS B SURFACE

3)CLASS C SURFACE

• SURFACE A+C

• FINAL SURFACE

• CLOSED SURFACE

TREE STRUCTURE

 4. DRAFT ANALYSIS.

CONCLUSION :-

Coin holder plastic component using class A surface have been succesfully created and draft analysis performed.
