Week 8 - Challenge 4 - Bumper

Week 8 - Challenge 4 - Bumper

OBJECTIVE

• To Create or Develop Class B and Class C Surfaces of Bumper from the given Class A Surface.
• To Determine the Tooling Axis for the component.
• To Analyse Bumper by featured Draft analysis in Catia V5

• Shown Screenshot is given Class A surface from the Design consideration team.From the surface create a centre point of the surface and add axis system from the point.
• I determine the possible tooling axis is X Direction.and also analyse on this axis by featured Draft analysis of the Class A surfaces.

• By analysis shown a resultant, X direction is a posssible Tooling axis.

CLASS B Creation

• By offsetting the Class A surface at 3mm distance (Because component thickness is 3mm).
• Somewhere surface section are break by offset the surface
• where, sections are broke are reconstruct by using Extract, Untrim and Extrapolate features
• then Combine those section to the Offset surface.
• After the Class B surface as Created

Screenshot is shown as CLASS B surface

CLASS C Creation

• From the Class A surfaces using Boundary command to all edges of the surface
• then sweep those section by define by reference surface with guiding of boundaries
• sweep at the angle of 90 degree at distance of 5mm
• then one sweep to another edges are extrapolate 2mm and trim those edges.
• after that join all Sweep section of the surface and considered as Class C surfaces.

FINAL Bumper Creation

• Join Class A and Class C surfaces
• Then Trim Class B and Join of (Class A and C surfaces).
