Week 9 - Attachment Feature Creation - Challenge 2

Aim:- To Create the Dog House for the Door Trim considering the design rules mentioned in the video.

Tooling axis:-

Here, the first tooling axis is blue coloured, it is taken for the Class A to solid conversion. It is taken by extracting the plane along the ejection side and taking the line normal to the surface passing through a point taken on the extracted surface.

The second Tooling axis is Called the sliding tooling axis taken to give draft for Dog House. it is taken long X direction or perpendicular to the blue tooling axis and passing through the same point.

Draft Analysis on Class A:-

Here the 3 degree initial draft is taken and the obtained output suggest safe ejection of the part.

Draft Analysis on Final Plastic Part With Dog House:-

Here, the 0.5 degree draft is given on the Dog house . hence the draft analysis is done at 0.4 degrees and the result shows safe ejection of part.

Draft analysis on Dog House Inner faces:-

Same 0.5 degree inner draft is taken and the analysis suggest safe ejection of part at 0.4 degrees.

Dog House Calculations:-

T = 2.5mm.

C thickness = 1 mm ( as the base thickness is 2.5, 40% of that is 1mm).

B thickness = 4 mm ( between 3mm and 6mm)

Outer edge fillet= 2mm.

Inner edge fillet = 1mm

Draft ( inner & outer) = 0.5mm.
