Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

Objective:

To create tooling axis for the fan cover model and perform the draft analysis.

Draft analysis feature:

This command is used to detect if the part you drafted will be easily to be removed. This type of analysis is performed based on the colour ranges identifying the zone on the analyzed element where derivation from the draft direction at any point corresponds to the specific values.

Draft is the angle in which the part is tapered to release. As the part cold, it tends to want to shrink the core side of the mold.

Adding draft helps to release the part easily.

Tooling axis :

The tooling axis is the axis in which the mold or core cavity opens.

Tooling axis creation :

The connectivity of a class A surface can be determined by creating the boundaries or by using the join command and see how it will be connected.This is the first step to check the connectivity of class A surface.

The clearance check of all the axis direction will be done by creating intersection along the axis on a plane by creating the new axis system with the model and constructing two line with the walls.A line bisecting the two lines and passing through the point will be a tooling axis.

Dummy tooling axis:

The dummy tooling axis is directly created by the point to direction line command.

Creating the tooling axis along the X axis by using bisection method:

Using the intersection command the lines creating along the inclined walls,this lines are creating the tooling axis along the X axis.in the line command the bisecting lines are selected and then both inclined lines selected along with the point created at the center of the part.

Then the bisecting line is created along the X axis.

Creating the tooling axis along the Y axis by using bisection method:

Using the intersection command the lines creating along the inclined walls,this lines are creating the tooling axis along the Y axis.in the line command the bisecting lines are selected and then both inclined lines selected along with the point created at the center of the part.

Then the bisecting line is created along the Y axis.

Tooling axis creation by using bisecting method:

For the tooling axis the line command is selected in which the bisecting option is selected after the both tooling axis X axis and Y axis are selected along with a point which is created at the center of the part.

The tooling axis is created and to visualize more easily add color to it convert into a dash line

Publication:

Publication is used to make it easily accessible for publishing the components.

Draft analysis :

Draft analysis is done after determined the tooling axis

Draft analysis is used to check if the minimum 3 degree draft is maintained, if minimum 3 degrees draft is provided the whole part is converted into green colour.
