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

AIM: Create the tooling axis for the given Fan cover model meeting the requirements of the draft angle and perform the Draft analysis on the model.

REPORT ON DRAFT ANALYSIS: 

STEP 1: 1st to check the connectivity of the Class A surafce.

• Ensure that there is no gap between the component, using join command.
• We can visually check it or by clicking boundary command>
• After that disassembled.

• It has 2 boundary , Outer and inner hole.

Therefore the 1st design check is completed.

STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.

• Check visaully which is the best possible tooling axis.
• Check all three axis.
• Along x and y is not possible.
• Z is the best possible tooling axis.

Creating a Tooling axis along x and y:

Intersect the zx plane with the fan component. As a result we get 2 line of zx plane.

Create a tooling clearing axis through x direction using bisecting line.

Similarly create tooling clearing axis through y direction using bisecting lines.

Now create a bisecting line using 'tooling clearing x direction' and 'tooling clearing y direction'.

After that publish the tooling axis and Class a Surface so that it is easily accessable.

Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.

Then after opening the draft analysis tool box go for the compass and place the compass alinged to tooling axis and click on the lock symbol after alinging and further click on the surface.

 

Then it will be shown green colored.

Now measure individually.

EXPLANATION ON BISECTING METHOD:

Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In Bisecting method, bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other. In order to know whether the particular surface is toolable or not we intersect the surface with the respective plane and get a sketch which consist of two lines and with the help of bisecting line option we bisect the line which creates a line at the mid point of the two lines. Like wise we create tooling clearing axis for x and y which will be used to create the main tooling axis using the bisecting line option in in the line comand.
