Week 8 - Challenge 4 - Coin Holder Design

AIM: TO CREAT THE COIN HOLDER DESIGN BY CREATING CLASS A B C SURFACES

OBJECTIVE: To creat a design a perform a draft analysis

INTRODUCTION :

CLASS A SURFACES - The surface which is givem to the pkastic modeler which is of aesthetic and outer most surface and the surface made by the designer known as clasa a surfaces

CLASS B SURFACES - The surfaces which is under the class A surfaces and which contain some engineering aspects on it is known as class B surfaces

CLASS C SURFACES - AT THE END the all classes of A B are going to be join called class c surfaces

FLOWING THE PROCEDURE STEPS:

1) CREATING A TOOLING AXIS

2) PERFORMING DRAFT ANALYSIS

3) CREATING A CLASS A SURFACES

4) CREATING A CLASS B SURFACES

5) CREATING A SOLID MODEL

HOW DO WE A CREAT A TOOLING AXIS ??

INITIALLY Obseve the class a surfaces before going to creat the tooling axis, and check wether it contain any discontinity and joined properly or not, have to check in all the x y z direction and we have to go with the top line and creat a axis called tooling axis

• Creat an intersection where we required, creat two lines at required intersectiojn and creat bijection line between them and also creat a dummy tooling axis
• extracting the suurfaces due to fillets and offset them upto 3mm\

in this coin holder actually iam not getting an draft analysis, i tried many times but getting -ve in some areas and i rechecked my class a surface to rectify the draft analysis but in the class a i dint found any draft analysis...
