Week 8 - Challenge 4 - Bumper
GIVEN CLASS A SURFACE:
TO Find the tooling axis of the component:
Check the connectivity of the surface and ensure there will be no gap between the surfaces and then define the tooling axis.While creating a tooling axis please ensure to give the tooling axis on a flat length surface
DRAFT ANALYSIS:
Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.Once the draft analysis toolbar is opened, go to the display block and select the 'Analysis under the running point' command to check the angle for different sides on the class A surface. The color scale on the bottom visualizes, whether the draft angle meets the requirements or not (3 deg) by indicating the colors Green, Blue and Red. Once the draft angle analysis was done, we need to align and fix the compass to the tooling axis of the class A surface.
Now creating Class B Surface:
Kindly offset the class A surface to required thickness ie, 3mm , to get the class B surface.
in above screen shoot some of the edges are open kindly create the edges by extrapolate command and trim them and join to Class B surface to get single boundry no more openings in edges/surfaces.
Now creating Class C Surface:
C surface has been created from the boundary lines of class A surface and by extracting the supporting surfaces then sweep the boundary lines with reference to the extracted surfaces.Create a sweep with reference to the curve and the reference surface with a 90 degree angle(for surface edges parallel to tooling axis)
Create a sweep with reference to the curve and the reference surface with a 3 degree angle(for surface edges perpendicular to tooling axis)
and give the inside direction Check for the continuity of the surfaces if there is any gap go for extrapolated and trim all together now we will get the class C surface
now join the class A and Class C surfaces
trim the above result with class B to get the req component
Closed Surface:We then switch to part design to create a final platic component using closed surface option.
final part component:
