Week 9 - Attachment Feature Creation - Challenge 2

AIM Create the Dog House for the Door Trim

INPUT Given Class A surface and take the thickness of the components 2.5mm

Tooling axis: Tooling axis is the direction at which core and cavity opens.

Procedure for creating tooling axis

• First check the connectivity of the given Class A surface by using the Boundary or Join feature to visualized and repaired the open edges of the surface.
• And then, analyse visually the best suitable plane or surface for tooling axis.
• After that, create a centre point on surafce for creating the axis on the point.

• Create a normal line along the extract suraface by using on surface type line for tooling axis

Design considersation for dog house

• Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ).

• The height of ( B ) should be between 3.0 – 6.0 mm

• Minimum draft (D) angle for doghouse is 1.5 degree to die draw

Draft Analysis

Darft analysis is a tool perform to check the product easliy removed from the core and cavity. In other word in draft analysis we check the product easily clear the minumum draft (3 degree).

Screenshots of the Draft analysis report for the given Class-A surface

In the Class-A suaface draft analysis, all surface show green which means it clear 2.9 degree draft angle but few surface show blue and red which means the surface has draft angle less than 2.9 or negative draft.

Outer Surface

The all outer surface of the dog house show green at 1.45 degree draft angle along side core axis.

Inner Surface

The inner side and upper surface of the dog house show blue in the draft analysis which means draft of the surface is more than 0.45 degree along side core axis.
