Week 8 - Challenge 1 - Base Bracket Design

AIM : To make a model from given class B , class C surface and perform draft analysis .

Objective :

• To perform draft analysis on class A surface .
• To create class B surface .
• To create class c surface .
• To create a solid body using close surface feature .
• To create draft analysis in final product .

Introduction :

Class A surface :

• It is given as input to plasticdesigner .
• It is a aesthatic surface .

Class B surface :

• It is surface which is used for engineering purpose.

Class C surface :

• It is the surface joining class A and class B .

Methodology :

• Creating tooling axis.
• Draft analysis.
• class B surface .
• class C surface.
• MAking solid from it using close surface feature.

Tooling axis :

• First ensure that the class A surface is join.
• As it has 2 hole in Z direction , so Z direction is most suitble for tooling direction .
• First we create dummy tooling direction.
• Now intersecting ZY plane and creating line by bisceting command .

Given Class A surface :

Dummy tooling axis :

Intersecting ZY plane :

Creating tooling axis by using two line created from intersecting plane and using bisect command .

Tooling Axis :

Draft analysis :

• Change the view mode to custamize view parameter and select material .
• Align the compass with the tooling direction.
• now click on the surface .
• Surface colour is green which mean that it has minimum 3 degree draft angle , which is sufficient in plastic component manufacturing .

Creating class B surface :

• Extracting the ribs and flat surface one by one and performing below command .
• untriming the the surface.
• extrapolating it.
• offsetting it to 2.5 mm in downward direction .
• Now doing trimming .
• And finnaly giving fillet of 3+2.5 = 5.5 mm which is equal to the fillet radius + thickness .

Extracting

Untriming :

Extrapolating:

Class B surface :

Creating class C surface :

• Extract the boundary of class A surface .
• use sweep command and using drafting in it to create draft angle of 3 degree.
• join the class A surface and class C surface and trim it with class B surface to get final class C surface .

Creating solid :

• Now use close surface command to create solid from it.

Conclusion :

• Created class B and class C surface .
• Created a solid body .
• Perform draft analysis .
