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

Aim;

To Create Draft Analysis and Tooling Axis For the Given Fan Cover Component.

STEP BY STEP PROCEDURE;

Tooling Axis: The axis at which both the core and cavity moves to manufacture the molten plastic component, Tooling Axis is made at which all the surface of the component can be made during the manufacturing process without using side cores,Thus the component can be made cost effective.From Tooling Axis view all the surface of the component should be visible so that we can make sure Tooling Axis which we made is correct.

DRAFT ANALYSIS: Draft analysis is a tool which is used to check the draft angle of the components.Every component should have atleat 3 degree Angle So that the product can be easily ejected without any damage while manufacturing.

BISECTING METHOD: Intersection of the component should be taken using xz axis And the surfce which we feel could not clear the minimum 3 degree angle line should be drawn along that,so that two lines will be obtained bisecting line should be created using that two line and that bisecting line is your Tooling Clearing XZ axis. Like Same Way Tooling Clearing YZ axis should be made. Bisecting line should be drawn using Tooling Clearing XZ axis and Tooling Clearing YZ axis That line is your Tooling Axis.

Dummy Tooling Axis:

Intersection of XZ Plane:

Tooling Clearing XZ Axis:

Tooling Clearing YZ Axis:

Tooling Axis: (Bisecting Tooling Clearing XZ and YZ)

Draft Analysis:

Axis system should be placed on the top of the tooling axis.

Colour Variation will be shown for the angle above 3 degree will be shown in green and below green will be shown in red.

Using the compass we can check the angle on the component
