Week 8 - Challenge 1 - Base Bracket Design

Challenge Report (week 8 ch1)

Tooling axis:

• Checked for the feasibility of tooling axis along x, y, z axes.
  • Z axis has been selected as tooling direction.
• Created a dummy tooling axis along the large hole.
  • Created an extended line along the direction of the line of concern.
  • Created a bisecting line along those lines.
  • Using the draft analysis tool, placed the axes aligning to the obtained bisecting line (tooling axis).
• Identified the surfaces which might cause the problem in removal.
• Created a tooling axis with respect to the class A
• Performed draft analysis using the draft analysis tool.
• Created a dummy tooling axis orthogonal to class A.
  • Using the picking tool inside draft analysis, checked for the draft angle on the class A surface.

Created a separate geometrical set by the name B Surface.

• Created 2 ribs without fillet and offset at 2.5mm
• Created inclined surface and base surface and offset them at 2.5mm
• Applied fillets at different places as required.
• Rename the last command as the B Surface.

[note: all the surfaces had to be extrapolated for proper trimming]

Created a separate geometrical set by the name C Surface.

• Created a boundary for sweep
• Swept the contour of the surface at 3 degrees draft angle.
• Swept the holes separately at 3 degrees draft angle.

Joined the class A and class C surfaces. Later trimmed it with the B surface.

Then in part workbench, given it a closed solid.
