Week 8 - Challenge 1 - Base Bracket Design

AIM:

• To analyse the given Class A surface using feature draft analysis.
• To create class B & C surface from Class A surface.
• To create a close surface of given class A surface model.

Draft analysis:

• Draft analysis is used to detect the given model drafted can be removed easily.
• Given Class A surface is analysed using feature draft analysis.
• Check the given class A surface for any connex issuses.
• Customise the view mode and apply material option.
• Color code of draft analysis is shown in the picture.
• Green gives good drafting angle
• Red is neutral drafting angle
• Blue is in negative drafting angle.

Tooling axis creation:

• Create a reference point in a given hole.
• Create a line using point as dummy tooling axis.
• Bisect the given class A surface by creating a plane and use intersect command.
• Inclined line is created for both inclined surfaces.
• Using bisecting line tooling axis is created.

• After creating tooling axis,all the surfaces are extracted and untrim the surface.
• Untrimmed surface is extrapolated.
• Extrapolated surface is trimmed down and use offset command and form surfaces.
• Fillet is given in class B surface with wall thickness.
• Class B surfaces is formed
• Class C surface is sweeped from class A surface.
• Class B & Class C surface is trimmed from class A surface.
• In part model,use Close surface command & form a part model.

Class B Surface:

Class C surface:

Final Trim:

Tooling axis using bisecting method:

• Intersect the given class A surface using intersect command along with a plane parallel to yz plane.
• Create lines on two inclined surface lines.
• From those two inclined lines create a bisecting line and choose a axis parallel to inclined lines so that tooling can be easily.
• Tooling axis is created.
