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

CREATION OF TOOLING AXIS AND DRAFT ANALYSIS FOR FAN COVER

 

Objective:

The main objective of this project is to create the tooling axis and the draft analysis for the fan cover using Catia V5.

Introduction:

The tooling axis is very important for the component to be manufactured, keeping that tooling axis as reference the part can be manufactured without any congestion and will ease the way in manufacturing the part. The draft analysis will show the important angles of the body, it is very important to maintain positive draft angle.

Methodology/approach:

• For the creation of tooling axis and draft analysis, the first important input is the class A surface, then further using Catia V5, create the tooling axis and draft analysis, first, Insert axis system.

• Check the best direction (X, Y, Z) and select the direction at which is very easy to manufacture. Z direction is selected for the Tooling axis, create the intersection curve at the ZX plane so we can check if any curves have different angle, for those curves we can draw the bisecting line to get the center axis for both curves

• The same method is carried out even in the ZY plane, that is creation of intersection curve and bisecting both the curves, to get the mid axis.

• Then using both the axis from the two bisectors, again bisect them to get the final tooling axis in Z direction.

• Publishing – Use the publish option to publish the Fan cover and the tooling axis, so to obtain the draft analysis of the part.

• Use the analysis>Feature draft analysis toolbar to check the draft analysis, Use the compass and place in the Z direction line being upwards and lock it.

• Select the axis and the part so that the color changes according keeping the reference as tooling axis.

• On the quick analysis mode there are 3 colors green, red and blue. We can change the values as per our standards, it is good to main standard drafting angles 0 to 3 degrees

• Analysis on running point - with the help of this option, the angles at every point can be checked easily.

• The draft analysis is completed for the for the class A surface.

Different views of the Fan cover:

• Front view

• Left side view

• Isometric view

• Top view

 

Conclusion:

The draft analysis and the tooling axis is created for the class A surface of the fan cover.
