Week 8 - Challenge 1 - Base Bracket Design

SCREENSHOT OF THE TREE STRUCTURE :

CREATION OF TOOLING AXIS :

after receiving the class A surface, first we need to study analsyis the surface and its draft angle which plays an important role in the product manufacturing.
study the class A surface that in which plane the product would be easily manufacturable.
In this case, the xy plane is chosen for manfaturing and to create the tooling axis.
so, for creating the tooling axis, define a point in the surface or in circular cutout.

yz plane is created along the point to the get the intersection lines of the surface.

after creating the intersection lines. create a line using a line definion command by selecting two points on drafted lines.

the line which pass through the mid point of the two line segement is known as the bisecting lines.
the bisecting lines are created by the reference of the two line in the above image, where the two line meets at the point and will be defined to give a bisecting lines
this bisecting line will act as the tooling axis.

CREATION OF DRAFT ANALYSIS IN CLASS A SURFACE :

for creating the draft analysis, go to insert - analysis - feature draft analysis.
place the axis system in the tooling axis and lock the position
then click on the surface which shows the draft analysis report
the minimum draft angle required for manfacturing a plastic component is 3 degree.

CREATION OF CLASS B SURFACE :

the class B surface is created by using the extract of class a surface. in this case, the fillets are avoided, to make ease of designing.
the class B surface is created with the offset 2.5 mm
while creating the fillets in class B, if the class B is under the class A then the fillet value will be ( fillets + material thickness )
if the class B is above the class A then fillets value will be ( fillet value - material thickness )
