Week 9 - Challenge 3 - Bumper

Object: To create a body of Bumper from the input given which was the A-surface of a Bumper.

STEP 1: Creation of Tooling axis

Tooling axis is the direction in which a core or cavity of mold opens. This Axis is very important to determine the orientation of the component in mold, core and cavity design.

STEP 2: Creation of Class-B Surface

For creating the Class-B surface the required surface except the offset surface have been extracted and then untrimmed all the surface.

STEP 3: Creation of Class-C Surface

• The required outer edges of the A-Surface were extracted using Multiple Extract. Then to avoid the patches the curve is smoothened using the Curve Smooth option.
• Then by using the sweep command the surface was created.
• Then, using extrapolate command, the edges were intersected between the surface corners, which eases the trimming operation.
• Now the required portion of the C-Surface was trimmed out.

STEP 4: Draft Analysis

• First the Class-A – Surface is checked before creating the Class –B & C surface and finally the solid body must be analyzed. Both can be done by following the below procedures.
• By changing the view mode to custom view parameters – Material mode then the feature draft analysis is enabled.
• Then the compass was activated and placed with the tooling axis by dragging the red pointer and then locking it.
• Then, by selecting the quick analysis mode, the nominal value will be 3 degrees and checked for the component's draft angle.
• The green colour area shows that it satisfies the 3-degree draft angle. If not satisfied then by using the Running point tool the area is measured and then altered to get a successful draft for the created tooling direction.
