BASE BRACKET

Tooling Axis creation:

Tooling axis is created for any component for the tool movement while manufacturing of the particular component.
To create a tooling axis for the component, firstly the design engineer should analyze the best tooling direction for the movement of tool in manufacturing.
Then create a point at the hole centre by selecting the circle/sphere/ellipse centre and also create a line passing through the point in the tooling direction.
Let us assume the created line as dummy tooling line.
At the same point, create a plane by selecting the 'parallel through point' option and select the preferrable plane direction.
Now make intersection curve on the component using the created plane and component.
The tool can easily move in horizontal and vertical directions to the tooling axis. For the slant directions, create a line by selecting point to point option. For the two slant curves, two lines should be created on both sides of the dummy tooling axis.
Now create an another line by selecting the bisecting option and then select the two created lines on both sides. From this bisection method, we can obtain a line in the preferred tooling direction and this line is known as the Tooling Axis.

Draft Analysis:

Draft analysis is done on the class A surface and the final plastic surface component as shown below.
The draft angle for plastic components ranges from 1/2 to 3 degrees and I have given a draft angle of 3 degree.
The results of draft analysis with colour scale variation is shown below.
