Week 8 - Challenge 3 - Coin Holder Design

Aim : To create a model from given class A surface and do draft analysis.

Objective :

• To create class B and class C surface
• to do draft analysis .
• to make report of it .

Introduction :

Class A surface :

It is asthetic part of car .

Class B surface :

It is surface for engineering advancement .

Methodology :

• checking continuity of surface.
• Tooling axis.
• Draft analysis.
• Class B surface.
• Class C surface .
• Making solid body .
• Draft analysis of final product .

Tooling axis :

• The direction in which the mould open and close is called tooling direction.
• Extract the base and create the point at the center .
• using intersection command , created the intersection with yz plane.
• Here tooling axis is created at the center because generally all surface are parallel to it.

Given class A surface :

Creating intersection :

Tooling axis :

B surface creation :

• B surface should be inside class A surface .
• All operation are followed for the part of class B surfaces (wall , base , flange) are :
• Extration of surface .
• untriming it.
• extrapolating.
• triming it .
• ofseting 2.5 mm which is thickness .
• Fillet it .

untriming it.

• extrapolating.

• triming it .

• ofseting.

Final Class B surface :

Creation of C surface :

• Boundary of class A surface is extracted and flanges are also extracted .
• Sweep command is used to create C surface at 90 degree of class surface .
• class C and class B are trimed and join with class A surface .

Creating solid body :

Finally solid is bodyis created by using close surface command .

Draft analysis :

• First the material mode is selected in custumize view swction.
• Now click on the compass tab and align it with tooling axis .
• Now click on the lock .
• click on the surface .
• Surface colour shows green , which mean that the it has more than 3 degree angle , which is good for manufacturing .

Class A surface :

Final body :

Different views are as :

Isometric view :

Front view :

Side view :

Top view :

Tree structure :

Publication :

Conclusion:

• Created class B surface and class C surface .
• Perform draft analysis .
