Week 8 - Challenge 3 - Coin Holder Design

CLASS A Surface -

For the clas A surface we select INPUT module and then create Class A Surface.

then check for continuity , for the continuity select boundry command and then visully check the boundry has continuous or not.

for the identification class A surface colored in pink

TOOLING AXIS CREATION-

1) select flat surface for the create tooling axis

2) selected surface extract

3)create point on the surface and then draw line by point indirction

4) For check the axis is write or wrong analysis by draft analysis

5) At the end the class A surface is ok with the tooling axis

created tooling axis is analysis on the class A Surface,the below figure shows that draft analysis of class A sureface.

Class B surface-

For the class B surface creation select class A surface And then class A surface different in parts like BASE, TOP WALL, SIDE WALL ,OUTER FLANGE and at last FILLET etc.

1) Extract the base of class A surface and then untrim that extacted surface

2) Then extrapolate both surface and trim it

3) and at last Offset that surface by 2.5 mm as per given instruction

4) for other surface creation same procedure follows as above used

5) AT last get the CLASS B SURFACE

CLASS C SURFACE- Class C Surface used for the join the class A and Class B Surface

for the Class C surface creation need Class A surface

1) Use boundry command and select the class A surface and create boundey.

2) Then this boundry use for the class C creation

3)Use sweep command , in sweep command choose line option and in line option select with reference surface

4) select boundry At surface And angal give as 90 degree and lengt 5 mm and give direction

5) Then class C Surface create like

6) And then class c surface join with clas A Surface .

7) Here need class B sueface Extrapolate

8) class A And Class C join surface trim with the Class B surface .

CLOSE SURFACE- For the close surface select part desingn command and then choose close surface option.

And then get close body of coin holder .

And at last check the close body for draft analysis by 3 degree
