Week 9 - Project - A pillar Design with Master Section

Tooling Axis and class A surface draft analysis.

Tooling axis can be created with the help of the mastersection curves given in the input. Two of the vertical lines in the master section of the dog house is extracted. A bisecting line is created bisecting the above extrcted two lines. This line can be used as dummy tooling axis.

As some of the class A surface don't satisfy the draft analysis main tooling axis is constructed 2 digrees deviation with the dummy tooling axis.

With the main tooling axis, all the class A surface satisfies the draft analysis.

Class B surface

Class B surface is created by offsetting the class A surface by 2.5 mm. The missing area is madu by sweep tool.

Class C surface

Class C surface is created by taking the boundary of class A suface and sweeping by giving draft direction as main tooling axis.

By joining class A and class C surface and trimming it with class B surface a closed surface is created. And the part body is created using Close Surface tool.

Engineering Features

The dog house is created with the help of master section and following the design rules. The boundaries of master section is extracted and extruded to create the surface of dog house. Outer surface is given draft with respect to main tooling axis. Lifter axis is created with the help of master section. The axis is created in a direction perpendicular to the master section plane. The inner surface of the doghouse is given a draft angle with respect to lifter axis and fillet is given. The dog house is trimmed with the main body.

Part Draft analysis.

All the class A surface is satisfying draft analysis. except for small areas in class C surface which is allowable.

Draft analysis of engineering features

Outer surface with main tooling axis

Inner surface with lifter axis

All the surfaces satisfy draft analysis.
