Week 8 - Challenge 2 - Switch Bezel Design

AIM:

 Create the Switch Bezel  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 Switch Bezel  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

• Then using the Boundry create a Bisecting line B/w 2 edges of a component along one plane

• Then create one more line with respect to other side surface of the component,for that given 3^0 WRT surface

• created the tooling axis b/w those two lines created above using Bysecting 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:

• 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 All the sides and Top Surface
• Side surfaces of switch bezel

• Top Surface

• 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 seperataley
• 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 base bracket plastic component 

•  perform the Draft analysis on the Finle model. 

From the above figure we can observe it is satisfying 2.9^0 draft It's Approximately 3^0 nominal draft

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/Back view

• Side view

• Top view

CONCLUSION:

The Plastic Component is created & Draft analysis is Done
