Week 8 - Challenge 4 - Bumper

DESIGN BUMPER -

DESIGN PROCEDURE -

1) Class A surface check.

2) Creating tooling axis.

3) Draft analysis on Class A surface.

4) Creation of Class B surface.

5) Creation of Class C surface.

6) Final trimmed surface.

7) Convert surface to solid.

1) Class A surface check -

This surface is provided by styling team. This Class A surface is check by using boundary command, if there is irregularities then it is clear by using join command.

Then by using publication tool Class A surface is published.

2) Create tooling axis -

Tooling axis is a line of direction where core and cavity will open.

In bisecting tooling axis method, analyze the model manually or visually to see which direction is most suitable for tooling axis.

After checking all three direction, creating a point at the centre of the surface which is extracted.

At that point we creat a axis system. Then by selecting XZ plane the Class-A surface is intersect.

Then two lines are drawn to the side faces of the intersected curves. Then we create one more line by bisecting this two line. Which our tooling axis.

Then published tooling axis by using publication tool.

A) BISECTING TOOLING AXIS -

B) NORMAL TO THE SURFACE TOOLING AXIS -

3) Draft analysis for Class-A surface -

By changing the view mode to custom view, in the parameters – Material mode is selected. Then the feature of draft analysis is enabled.

Then the compass was activated and placed with the tooling axis by dragging the red pointer and then locked it.

Then, by selecting the quick analysis mode, the nominal value will be 3 degrees and checked for the components 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.

4) Creation of Class-B surface -

For creating the Class-B surface, we offset Class-A surface in downward direction by 3mm.

Then all the missing fillet patches or other surfaces are created by using multipale extract,extrapolate and trim command.

Finally, the required corners have been filleted by reducing the thickness value 3mm

Then published Class-B surface by using publication tool.

5) Creation of Class-C surface -

For the creation of Class-C surface, creating the boundary for Class-A surface.

Then by using the sweep command the surface was created by selecting respective boundary.

So get our Class-C surface.

After that we published Class-C surface by using publication tool.

6) Final trimmed surface -

Now the Class–A surface is join with the surface which created by using sweep command.

Now this join is trimmed with Class-B surfaces.

We got required final trimmed surface.

Then published final trimmed surface by using publication tool.

Draft analysis for final trimmed surface.

7) Convert surface to solid -

Now in part design workbench the final trimmed surface is converted into solid part by using close surface command.

Then solid body get mirror.

Various Orientations -

1) Isometric view -

2) Front View -

3) Side View RH -

4) Side View LH -

5) Top View -

6) Bottom View -
