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

Draft analysis of fan cover:-

We got the fan cover to check the draft analysis of 3 degrees on it. Before checking or starting the procedure for draft analysis we need to check the surface. Initially we check the gaps between the surface and also check the no. of surfaces we have because, we need just one single joined surface for draft analysis. If the gaps were found then we will join the surface.

Initially we check the tooling direction by visually observing the part or surface. After calculating or finding the no. of possibilities than we start the draft analysis according the cheapest and best way to do the manufacturing by avoiding side cores and easy manufacturability for the part or surface creation.

Initially we create a point for center or tooling direction creation. Then we create axis system by using that point with reference to main axis system. Now, we create the intersection line on the surface by using of zx plane or coordinates. Then we draw line with using point to point feature on the lines which we have doubts for not clearing of tooling direction. Then we draw vertical bisecting line by using these two lines and center point which we were created. This will be tool clearing in x direction.

Now we follow the same procedure for tool clearing in y direction also. For doing this we check the lines which or not perpendicular or parallel tooling direction.

After creating the both tool clearing both tool clearing in x direction and tool clearing in y direction. Now, we draw a bisecting line with these two lines. This will be our “TOOLING DIRECTION” for the fan cover.
