Week 9 - Challenge 1 - Base Bracket Design

AIM : To 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.

REPORT ON DRAFT ANALYSIS:

Given Class A Surface:

STEP 1 : To check the connectivity of CLASS - A surface by ensuring there is no gap between the component by using Join or Boundary Command. Design check is completed.

STEP 2 : Find the tooling axis of the component. The tooling axis is the axis from which mold opens and closes or the cavity opens and closes.
Along X it is possible but expensive and Y is not possible. Z is the best possible tooling axis.

STEP 3 : Creating a Tooling axis along z using bisecting method:

EXPLANATION OF BISECTING METHOD:

Bisecting method is used to find the proper tooling axis using the dummy tooling axis. In Bisecting method, the bisecting line is used for either bisects the two lines or it will show an error which means the two lines are parallel to each other. To know whether the particular surface is tolerable or not we intersect the surface with the respective plane and get a sketch that consists of two lines. With the help of bisecting line option we bisect the line which creates a line at the mid-point of the two lines. The created line from the midpoint of two lines acts as our main tooling axis.

Therefore the main tooling axis is along the z-axis.

STEP 4 : DRAFT ANALYSIS OF CLASS A SURFACE:

• Now perform the Draft analysis using the Featured Draft Analysis tool in the tools. Before performing the draft analysis ensure the surface should be in material mode.
• Open the draft analysis toolbox and select the compass and try to align W-Component with the main tooling axis and later click on the lock symbol after aligning.
