Week 9 - Attachment Feature Creation - Challenge 2

REPORT:-

INPUT-Class A surface

its boubdasry ci cheked. Its a single boundary.

Tooiling Axis Creation-As a flat surface is present, line normal to this surface is taken as tooling axis.

for this part, bisecting method is not used to create tooling axis, as flat surface is present.

Draft Analysis-

for the created tooling axis, class A is checked for the draft analysis. it is clearing analysis, hence part is ready to design.

B AND CSurfaces are created as per requirement.

Doghouse created using extrusion. with 1.3 mm thickness.

Doghouse Design-

Theoritical Values for different parameters-

T= thickness of part = 2.5 mm

C= Thickeness of doghouse near B surface = atleast 40% T = 0.4* 2.5= 1 mm.

(actual thickness, C in part = 0.901 mm)

Draft Angle for outer surfaces with respect to main tooling axis = 1.5 deg.

Draft angle for inner surfaces of doghouse, with respect to core tooling axis= 0.5 deg.

B= Height of slant portion of dog house= 3 mm to 6 mm.

Height of doghouse= 23 mm first lim, 5 mm second lim.

surface part and closed surface body, three are checked for draft analysis.
