Week 9 - Challenge 3 - Bumper
Draft Analysis of Bumper Class A surface:
1. Ensured that there is no surface gap in the given Class A surface; by Visually checking using Join operation preview command and giving merging distance as 0.001mm.
2. Analyzed the component to identify best possible Tooling Direction (Core & Cavity).
Steps to evaluate Tooling Axis:
1. Created a Geometrical Set, named it Tooling Axis.
2. Checked the CLASS-A surface in all three direction X, Y, Z. And confirmed that X direction is more suitable for TOOLING AXIS as most of the surfaces were visible in X-direction.
3. Created a point in the middle of a edge of the grill portion of the Bumper. And created a line in X-direction & used it as dummy tooling axis.
5. Carried out Draft Analysis on the Class-A with reference of dummy tooling axis with 2.9 degree draft.
6. As the Class A draft analysis showed green with reference to the dummy axis. Named the axis as TOOLING AXIS.
7. Then, Draft Analysis of Closed Surface was performed using the obtained Tooling Axis.
Draft Analysis:
Important step to perform prior to Draft analysis is to make sure that the View Mode is set to Material; then proceed.
Performed the following steps during Class A Surface analysis & Closed Surface Analysis:
1. After clicking draft analysis tool, use the compass to define new current draft direction.
2. Pick the red dot and drag the compass near the component. Then hold the dot and place it on the Tooling Axis. And click on the Lock symbol in Draft Analysis tool.
3. And select the component to be analysed. As per the colour code, the Component colour would change to indicate that the Draft values are within certain defined range/ band.
4. Generally, draft analysis is passed when the colour is Green for the selected component.
Result of Draft Analysis:
Class A Surface: After analysis the surface turned green in all direction denoting the surface draft is more than 2.9 degree.
Closed Surface: After analysis with draft angle as 2.9 degrees, the bumper was shown in green in either direction. Hence, the draft analysis was cleared for 2.9 degrees.
