Week 8 - Challenge 1 - Base Bracket Design

AIM:

Create the Base Bracket Plastic component through the given Class-A surface. Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

OBJECTIVE:

• To crate a tooling axis for the plastic component
• To create a base bracket of plastic component from given Class A surface.
• To perform the draft analysis over the plastic component.

PROCEDURE:

Generating tooling axis

• Doing the continuity check to ensure whether given class A surface is continuos or not.By using Boundry/jion method,It seems there is no dis-continuos boundry
• Create axis system with respect to Class A surface ,then create a Tooling Axis at where it is paralell surface & yz plane intersection using By secting method
• Perform draft analysis on the given class A surface,Below pic shows the result of draft analysis,It cleares that it has 3^0 draft throughout the surface as it is in green color

Creating Class B surface:

• First Extract the surface base
• untrim the surface base
• Then extrapolite wherever reuired
• Off set ClaasA surface to 2.5 mm ,then we will get desired class B base surface
• Similarly do the above procedure for both the sides and Top base
• Side1

• Side2

• Top base

• Then trim all the surfaces together
• Give the Fillets in required region And It's the finle Class B

Creation of Class C:

• Extract all the boundry of class A surface Then sweep it ,we will get the Class C surface
• Jion the class A & class C surface
• Then jion all the Class A,B & C
• Then convert this closed surface to part body in the part workbench,we will get the required base bracket plastic component

• perform the Draft analysis on the Finle model.

From the above figure we can observe it is satisfying 3^0 nominal draft ,but at some corner it's satisfying 2.6^0 (refer below pic)

Hence plastic component can be created

• solid model with the proper color code of the draft angle in various orientations
  • green-3^0
  • Red-0^0
  • Blue- negative side
• Isometric view

• Front view

• Side view

• Top view

CONCLUSION:

The Plastic Component is created & Draft analysis is Done
