Week 9 - Attachment Feature Creation - Challenge 2

AIM:

Create the Dog House for the Door Trim considering the design rules

OBJECTIVE:

• Create the Dog House for the Door Trim considering the design rules
• 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 2.5 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

• 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 plastic component

• Create theDog House for the Door Trim considering the following design rules.

• Operations done to create the Dog House & finle component

• perform the Draft analysis on the Finle model.

From the above figure we can observe it is satisfying 1.5^0 draft For Dog house outer walls

From the above figure we can observe it is satisfying 0.5^0 draft For Dog house inner walls,here weare observing some red areas ignore them because that region having another main tooling axis

• solid model with the proper color code of the draft angle in various orientations
  • green- 0.5^0
  • Red- 0^0
  • Blue- negative side & in this case in some area of C surface is also blue beacause it is having 90^0
• Isometric view

• Front view/Back view

• Side view

• Top view/Bottom view

CONCLUSION:

The Plastic Component is created & Draft analysis is Done
