Week 8 - Challenge 4 - Bumper

AIM:

 Create the  Bumper  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  Bumper of plastic component from given Class A surface.
• To perform the draft analysis over the plastic component.

IMPORTING THE MODEL 

• Open the downloaded IGES file make it has  class A surface by jioning all the surfaces

PROCEDURE:

• 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 point on Class A surface plane & create tooling axis on point & normal to  surface (On surface 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 with respect to tooling axis as it is in green color

 

Creating Class B surface:

• In this component Directly offset class A surface to 3 mm 

 

• Then repair the patches of  class B surface 

 

• To repair used the operations like multi surface,trim, jion etc with help of  tools like line,spline obtain the class B surface

 

• Similarly did  the above procedure for All the Patches

•  The finle Class B

Creation of Class C:

• Extract all the boundry of class A surface Separately by observing the complexity ,Then sweep them 
• Trim them together then we will get Class C surface

• Jion the class A & class C surface(by trimming)

 

• Then jion all the Class A,B & C Surfaces

• Then convert this closed surface to part body in the part workbench,we will get the required Bumper plastic component 

•   Then,the perform of the Draft analysis on the Finle model.
