Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

The ribs of the following component has been designed by tthe given design rules. The thickness of the component has been set at 3 mm thickness. The height then as per the design rules comes to 15 mm as the height should be 5 times the thickness.

After the height has been set the thickness of the rib has to be determined. According to the design rules thickness must come to 40% the thickness of the component. By this we know that the thciknees of the component comes to around 1.2 mm which id 40% of the thckness of the component.

After thcikness the draft has to be added. The minimu draft required is 0.25 dgrees and thus the draft for all the ribs inculding the screw boss has been added.

After the draft the ribs were added to the main component nad then filleted to the minimum fillet of 0.25 radii. on all the sides.

after the component has been designed according to the design standard rules we can carry out the rib root thicknes analysis.

For this an intersection was taken along the ribs and the profile created was then measured and verifed wether the design standards were followed.

The minimum width at the top is more than .75mm. The draft is at .5 degrees. The thickness id 40% of the component thickness. Height is 5 times the component thickness. Minimum radii for the fillet is 0.25 mm. And from the rib root analysis the diameter comes to 3.2mm whereas the maximum preferred value is 1.3 times the thickness which is 3.9 mm.

As for the analysis of the final component. A point was taken on the surface of the final component and an axis was set along the point directly on top of it this was then taken as the tooling axis. After the tooling axis was creadted the draft anlysis was carried out. The draft axis was taken as the tooling axis and then locked into position and then the final component was selected as the element to be analyzed. The portion in green represents those portions have a minimum draft of 3 dgrees and then the protion in red shows the draft anlge less than 0. Thus the draft analysis was carried out.
