Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

AIM : To create the ribs and screw bosses for the Door Handle considering the design rules and also create the Door Handle component from the given class A surface.

DETAILED REPORT :

• Class A surface of Door Handle has been provided to us.

• TOOLING AXIS CREATION :

1. With the help of Boundary option, checking for any gaps between the surfaces.
2. Extracting one of the surface which will be suitable for creating the tooling axis.
3. With the help of Intersection and axis system, we created two lines from which by bisecting those two lines we made the tooling axis.

• B SURFACE CREATION :

1. First of all, we did the offset operation on the whole class A surface to 2.5mm.
2. After offsetting, we found that there is a little hole the B surface.
3. With the help of Multi Section surface and join option, we filled that hole to make that surface our final B class surface.

• CLASS C SURFACE CREATION :

1. With the help of boundary option, we selected the boundary first to perform sweep operation.
2. We selection sweep option and with reference surface we extended the surface in the downward direction upto 8mm with 90 deg angle.
3. Then, by Join operation, we joined the class A with Class C surface.

• At last we did the final trim of Class A+C surface with Class B surface, to get the final component.

• In Part design, by selecting close surface, we mase the component.

• RIB DESIGN CREATION :

With the help of the above design configuration, we created two ribs separated by the distance as shown in the picture of the question.

• CREATION OF SCREW BOSSES :

With the help of above design specifications, we created two screw bosses as asked in the question.

• At last by union trim, we joined the ribs and by assembly operation we joined the screw bosses to the main component, we got the final desired output.

• DRAFT ANALYSIS : At first, we did the draft analysis on Class A surface.

Atlast we did the draft analysis on the final component in which ribs and screw bosses both have the draft of 0.5mm.

• TREE STRUCTURE :
