Week 8 - Challenge 3 - Coin Holder Design

AIM:

Create the Coin Holder Plastic component through the given Class-A surface. 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.

TOOLING AXIS

To create the tooling axis we need study the class A surface and there is no gap between the surface. Create the point on the surface after create the tooling axis.

DRAFT ANALYSIS:

Draft analysis used to analysis the part for proper draft angle. It has 3 color scale green blue and red and maximum draft angle up to 3deg.Finally fix the compass on tooling axis on Class A surface.

Class B surface
I perform in this surface in 3 ways
1)Side wall

2)Base

3)Top wall

Side wall

From class A surface i perform the 5 operation.
Extract,Surface trim,Extrapolate,Trim and Offset.

Offset done by 2.5mm.

Finally fillet done.

Base

From class A surface i perform the 5 operation.
Extract,Surface trim,Extrapolate,Trim and Offset.

Offset done by 2.5mm.

Top wall

From class A surface i perform the 6 operation.
Extract,Surface trim,Extrapolate,Trim,Join and Offset.

Offset done by 2.5mm.

In this top wall I create the boundary for extrapolate. The boundary was created by two vertex selected in corner of the surface.

I faced lot of issue during creating this extrapolate and to get final output.

Class C surface

In C class surface we have to create the edge surface of the coin holder.

For this I use the sweep command for creating the surface and need to trim.

Need to create the cutout so I done Extract, Surface trim, Extrapolate, Trim for to create the cutout.

Closed surface

Finally i done the closed surface command to conform all surfaces are closed.

Draft analysis

Here i done the draft analysis is to conform the drafting we made 3deg. Because 3deg is maximum permissible for part.
