Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

1) FAN cover

Draft Analysis: Draft Analysis is done to check whether the part created can be removed easily from cavity easily. It is done by giving different color zones which shows any deviation from the specified draft angle and direction.

Tooling axis: It is created to specify the direction through which core has to pass into the cavity region. It plays a vital role in determining the direction of core as it should not affect the final product after cooling when it is removed. It should be in such a way to prevent side cores so that the cost will reduce.

Steps for specifying tooling axis:

• Use Join command and confirm that surfaces are joined together properly with no gaps.
• Analyse the surface model and decide the best tooling direction.
• Create a point at the center, and create axis system at that point.
• Draw the line from that point and name it as dummy tooling axis.
• Intersect surface and XZ plane, get the boundary line at the intersection.
• Create the two lines from the angled line on the either sides.
• Create a bisecting from those two lines, name it as a Clearing axis in X-direction.
• Intersect the surface and YZ plane get the boundary line at the intersection.
• Create the two lines from the angled line on the either sides.
• Create a bisecting from those two lines, name it as a Clearing axis in Y-direction.
• Create the bisecting line from the obtained two bisecting axis.
• Now name it as a Tooling axis which is required axis for the tool passing.
