Draft Analysis on a Fan Cover

OBJECTIVEVE :-

To Draft Analysis on fan cover using Catia V5 Software with suitable Tooling Axis

What is the Draft ?

Drafts are defined on molded parts to make them easier to remove from molds.

There are two ways of determining the objects to draft: either by explicitly selecting the object or by selecting the neutral element, which makes the application detect the appropriate faces to use.

Major Industries use the minimm Draft angle is 3 degrees.

PROCESS OF DRAFT ANALYSIS -

First we check the continuity of the given Class -A Surface.

Check the Tree Directions (X, Y, Z – axis) and Finally we Decided which is the Best possible Direction to Produce a Mold. That direction of axis is Called Dummy tolling Axis.

A Fan with several drafted surfaces that is oriented in part location. That the Draft Analysis initially Assumes a Z-axis Direction.

At Z-axis Drection The Faces are eaither Positive or Negative Draft So the Z- Axis We taken as Dummy tooling Axis.we need to create a prfect Tooing Axis.

PROCESS OF TOOLING AXIS CREATION -

What is the Tooling Axis ?

Tooling Axis means Direction In which The Mold opens Or Core and Cavity Opens.

Create a Axis system On a Point

Create intersecting line on the ZX- plane and Class -A surface,

Further produces the lines by using Surface points,

Finally Create the Bisecting line that is called as the Tooling clear in X- Direction.

Again we create the Same process on YZ -plane and Class -A surface, further produces the lines by using Surface points, Finally Create the Bisecting line that has the Tooling clear in Y- Direction.

Finally create the bisector line with Tooling clear in X- Direction and Tooling clear in Y- Direction.That Bisector line is Called as the Tooling axis.

PROCESS OF DRAFT ANALYSIS –

The first step is to change your shading style to “shading with Material”

Go for draft analysis (INSERT - ANALYSIS - FEATURE DRAFT ANALYSIS )

This can be done with the dragging of the compass with respect to Tooling axis.

Dragging Method -Begin clicking on the compass direction icon within the draft analysis dialogue box. This will be snap the compass onto the Tooling axis.
