Week 9 - Project - A pillar Design with Master Section

AIM:

Create A pillar Design with Master Section

OBJECTIVE:

• Creation of proper tooling direction following the master section to create the part that meets the requirements
• Draft analysis check to make sure that the class A surface is meeting the draft required along the tooling direction
• Creation of Dog house, Locators, and ribs to meet the draft analysis on the side core axis for the dog house

IMPORTING THE MODEL

• Open the downloaded IGES file and make it has a class A surface by joining all the surfaces

PROCEDURE:

• Doing the continuity check to ensure whether the given class A surface is continuous or not. By using the Boundry/join method, It seems there is no dis-continuos boundry
• create a 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 the draft analysis, It cleared that it has a 3^0 draft throughout the surface concerning the 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, join, etc with help of tools like line, and spline to obtain the class B surface.

Creation of Class C:

• Extract all the boundaries of class A surface Separately by observing the complexity, Then sweep them
• Trim them together then we will get Class C surface
• Join the class A & class C surface(by trimming)
• Then join all the Class A, B & C Surfaces
• Then convert this closed surface to the part body in the part workbench, we will get the plastic component
• Create the House considering the following design rules.
• Operations did create the Dog House & file component.

Draft Analysis:

Create the dog House considering the following design rules

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

• solid model with the proper color code of the draft angle in various orientations
  • green- 1.5^0
  • Red- 0^0
  • Blue- negative side & in this case in some area of C surface is also blue because it is having 90^0

CONCLUSION:

Created A pillar Design with the help of the Master Section.
