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

AIM:-

Creating the draft analysis and the tooling axis creation the way of creating the tooling axis particularly the bisecting method.

OBJECTIVE:-

1. To ensure proper tree structure is followed.

2. Geometrical sets should have a proper name based on the sketches present inside of them.

3. All the sketches should be created under the geometrical set.

4. To publish the tooling axis and class-A surface.

PROCEDURE:-

Tooling Axis- First import the given class A surface model i.e, Fan cover in Catia v5.

Draft is the amount of taper for molded or cast parts perpendicular to the parting line. It can be measured in degrees or mm.

If the mold is to be removed from the top, the box should be taper in towards the bottom, such that measuring the bottom internal dimension will yield a smaller lemgth and width than measuring the top from which the mold is extracted.

The manufacture of part that incorporates zero or negative angles may require a mold that can be separated into two or more parts, in order to release the casting.

DRAFT ANALYSIS:-

To perform Draft analysis on the model. Go to menu bar>select insert>Analysis>Feature draft analysis.

To give the draft direction, use the compass and align Z-axis of it with the tooling axis which we created for the model. Once it properly aligned lock the draft direction.A red colour point will be shown on screen, select the fan cover and it will show us the current draft angle of the model. Set the draft value to 3 deg under the colour scale variant and press.

Using the Analysis option under the display tab we can perform the draft analysis on the given model.

To publish the Tooling axis and class A surface, first select it and go to menu bar>tools publication. This will publish the tooling axis and class A surface which can be seen in feature tree structure.

PHRASES USED:-

Draft- These are defined on molded parts to make them easier to remove from molds.

The characterstic elements are pulling direction, Draft angle, Neautral element.

RESULT:-

The tooling axis for the given fan cover model is successfully created and draft analysis has also been performed for the same.
