Week 8 - Challenge 1 - Base Bracket Design

STEP-1

FOR PLASTIC DESIGN

1) TOOLING AXIS

The analysis is done for 3degree draft. So as can be seen all the surfaces are more than 3deg.

Create an intersection of CLASS A surface with ZX plane and from the intersection create the tooling axis as shown below

• Create a bisecting line using the lines shown above.
• 
• THE GREEN LINE SHOWN IS TOOLING AXIS

STEP -2

CREATION OF CLASS B SUFRACE USING WITH RESPECT TO CLASS A SURFACE

• purpose of offseting class A surface and creation class B surface is that we can repair surface and can be check through curve analysis
• given fillets as per required

STEP -3

Creation of Class C Surface

• For creating this surface we have extracted the boundry of Class A using multi-extract and then converted to smooth curve.
• Now this smooth curve is swept along the draft direction with a 3deg draft.

STEP-4

TRIMMED SURFACE AND MAKE SOLID PART FOR PLASTIC MOLDING

CHECKING THE DRATING ANGLES
