Week 8 - Challenge 4 - Bumper

AIM:-To Create the Bumper Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Take the Thickness of the component to be 3 mm

OBJECTIVE:-

• Screenshots of the Draft analysis report for both the given Class-A surface and the final plastic component
• Screenshots of the solid model with the proper color code of the draft angle in various orientations (Isometric, Front, Side, and Top View).

TOOLING AXIS CREATION:-

The direction in which the mould open and closes is called the tooling axis direction.
Check the connectivity of the surface and ensure there will be no gap between the surfaces and then define the tooling axis.
While creating a tooling axis please ensure to give the tooling axis on a flat length surface or the surface which have a hole on it.
Create a point on the middle of the base surface by using point on the surface command then create a intersection for the surface and extract the reference lines which will be helpful for creating the Tooling axis.

DRAFT ANALYSIS:-

Draft allows for the component to release from the mould, most parts or applications require a minimum of 0.5 to 1 degree draft angle and 3 dgree draft angle is widely used as per the norm.
Change the material mode to customize mode before moving to the draft analysis.
Insert –analysis-feature draft analysis
Defining the draft direction Select draft analysis from the tool bar and click on the compass symbol and pull the compass from the right side top corner of the workbench and place it on the component where want to do the draft analysis. ‘W’ of the compass and tooling axis should be aligned on the same line.
Once the compass is aligned with the tooling axis click on the lock symbol and drag on the surface we will get a wrong mark then select that point a table will appear it shows the draft value on the table we can adjust the draft value and analysis it for all the edges and surfaces.
By clicking the on the surface and using the flipping tool we can assign the Flipping direction, the color of the surface change as per the flipping direction .
Analysis under running point and move the mouse on the surface and it will show the details of the surface deg direct at each and every point of the surface.

B SURFACE CREATION:-

The A-surface is offsetted by 3.00mm as it is the thickness required.

The offset surface is the B-surface but had some issues like in some areas those are corrected by closing them using commands like Multi section,Sweep,Offset and extract.

C SURFACE CREATION:-

The A and B surfaces are connected by another single surface which is called the C surface.

It is created by using sweep with A surface acting as the reference surface and curve created from the boundary of the same surface.

Sweep with draft direction is also used to create A-surfaces.
