Week 9 - Challenge 1 - Base Bracket Design

Aim: Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

STEP 1:

• Check the connectivity of the Class A Surface
• Ensure that there is no gap between the component, using the join command

TOOLING AXIS:

Tooling axis or Molding axis is the direction in which the core and cavity opens. It is basically the direction that the mold pulls apart. Creating a tooling axis is necessary to provide draft angle and analysis them. The tooling axis is created using Bisecting method.

STEP 2: Creating the Tooling Axis in Given part.

• Check visually which is the best possible tooling axis.
• Check all three axes.

Y-Axis

X-Axis

Z-axis

• z is the best possible tooling axis.

BISECTING METHOD:

Now creating Class B Surface:

CLASS-A surface:

• A surface made by the designer which is given as an input to the plastic modeler to work on. It is aesthetic surface and the outer most surface.
• It is aesthetic surface

CLASS-B surface:

• A surface below a certain thickness from the class-A surface is class-B surface.
• This is the surface that contains engineering aspects of a model.
