Week 8 - Challenge 1 - Base Bracket Design

BASE BRACKET CHALLENGE :-

FEATURE TREE:-

1)TOOLING AXIS:-

First We have class A Surface as input weather oute surface is closer or not,Natural tooling axis is created using holes center point towards tooling direction.

Check the Draft analysis of class A surface along with tooling axis/direction:-

DRAFT ANALYSIS:

The draft analysis technique is used to analyze whether our part model created in CAD is manufacturable based on the draft condition applied. Here the part should get easily removed from the panel Mold in case of plastic core and cavity

To perform draft analysis

click on Insert >>Analysis >> Feature Draft Analysis

• Once the draft analysis toolbar is opened, go to the display block and select the 'Analysis under the running point' command to check the angle for different sides (ribs and inclined plane angles) on the class A surface. The color scale on the bottom visualizes, whether the draft angle meets the requirements or not (3 deg) by indicating the colors Green, Blue and Red. Once the draft angle analysis was done, we need to align and fix the compass to the tooling axis of the class A surface

Creating class B class :-

1)Class B:-

CLASS B SURFACE:

B surface means thickness of a part it is not visible it is inside part. It will shows that core side of the plastic model.

• To create the class B surface, I considered the entire surface has 3 parts Side wall-1, Side wall-2, and Base surface'. If we directly offset the class A surface, fillets may lead to cause an error, to avoid the errors we need to extract the surfaces and untrim the extracted surfaces and extrapolate those untrimmed surfaces with point continuity. Now trim those extrapolated surfaces to the required shape. And finally, fillets were given to the final trim.

OPERATION'S in Class B Surface:

1. Extract & Untrim
2. Offset & Trims
3. Fillets

Fillets:-

CLASS C :-

Boundary of class A surface is extracted and Class C surface is created using sweep command along with tooling axis/direction with draft of 3 degree angle.Holes also created by using same sweep commads and.

JOINING OF CLASS A AND CLASS C SURFACE:-

FINAL TRIM BY USING CLASS B SURFACE:-

THEN DEFINE THE PART BODY/WORKBENCH & FILL THE SURFACE BY USING CLOSE SURFACE COMMAND:-

FINALLY WE GOT CLASS C SURFACE & CHECK DRAFT ANALYSIS OF THE CLASS C SURFACE:-

THIS IS THE FINAL VIEW OF THE BASE BRACKET DESIGN OF CLASS A, B & C SURFACE.
