DESIGN FEA

AIM:--

To Create the Door Handle Component from the given Class-A surface.
To Create the tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
To Attach B side Features in the component.
To perform the Draft analysis on the model.

To be able to create solid from the given Class-A surface, by considering tooling axis and draft analysis.

1.The given Class-A surface:--

WHAT IS CLASS A SURFACE ?

It is an Asthetic surface and which is visible to the customers ie, Top surface,

2. CREATING TOOLING AXIS :--

Check for gaps between surfaces for that click on join and then preview.
If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm.

Extract the boundary and dissemble the boundary.
Find the correct tooling axis where the materal don't interfere with the tooling axis and all the elements can be created.
Create an axis system using at the centre of the Drill Holder.

Intersect the xy plane with respect to the class A surface.
Hide the class A surface and create point to point lines on the suspected drafts.
Create bisecting line with the two lines and point to create a tooling axis.
BISECTING LINES were used to get the exact medium from the two sides so that maximum positive draft angle can be achieved.

The tooling axis is created for the component by bisecting two lines.

3. DRAFT ANALYSIS:--

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok.
Now for draft analyses go to insert » analysis » feature draft analysis.
Use the compasss to define the draft direction.
In the colour scale change the draft angle to 3 degree.
The component changes to green in indication of passing draft angle.
Use running point to check the angle on the component.

The draft analysis is complete.

4. CREATING CLASS B SURFACE:--

Offset the CLASS-A Surface to 2.5mm in the inside direction.
There will be some minor gaps in the fillets area try to fix them out.
Then the CLASS-B Surface will be created.

5. CREATING CLASS C SURFACE

Extract the boundary from the class A surface using boundary command.
Using disassemble tool to divide the boundary as the boundary contains domains.
Use sweep command > choose profile type line > subtype as with reffrence to surface > choose guide curve and surface> draft angle as 90 degree > preview.
