Tooling Axis creation:
It is defined as the direction in which the mold/core and cavity open. Then resultant tooling
axis is created using the bisecting method.
Selection of the direction of the tooling axis depends on the ease at which components ca
be easily ejected.
By analyzing the component the most easily ejectable direction is somewhere close to the
Z direction,(might be inclined to it) so we have made a sketch on the YZ plane of the Axis
System) to create a bisecting line considering the 2 faces which might be difficult to be
tooled.
Taking the Thickness of the component to be 2.5 mm
