Week 8 - Challenge 4 - Bumper

DESIGN AND DRAFT ANALYSIS OF BUMPER DESIGN

Introduction:

The main goal of this project is to produce a plastic material of a Coin holder component that complies with OEM standards utilizing the provided class A surface.
Class A-surface Confirm the Correct Tree Structure. The name of a geometric set should be based on proper Standards.
Bumper Design in the car is parts that put some coins and bottles, cups, etc...

Aim:

This design aims to create a bumper design plastic component using the given class A surface following the OEM standard.
Perform the draft analysis and join Class A, Class B & Class C surfaces.

Class A Design:

The automobile design sector employs creates the class-A surface.
It describes the aesthetic Surface final it requires final production surface data.

Class B Design:

The class-B surface is the second surface from the class-A surface reference with a 3mm thickness.
This surface includes Plastic design engineering components.
These must also be "error-free" and smooth but are not bound to the same requirements as class A surfaces.

Class C Design:

Compared to Class A or B, the Class C finish allows greater flaws.
Class C specifications are frequently used for interior surfaces that are difficult to see, characters that will be hidden by another part when it is completed, or surfaces.

Material choose:

It is used the most frequently of any plastic in automotive manufacturing.
An acrylonitrile butadiene styrene (ABS).
It has excellent chemical and heat resistance and is generally resistant to impact. Given this plastic's resume, you will frequently find it in car bumpers, switch bezels, etc...
Most OEM bumpers are made out of plastic and feature an aluminum or steel reinforcement bar hidden in the middle.
Some bumpers may also contain polypropylene in order to help absorb energy during an impact.

Design Methodology:

Add the Bumper Design class A surface design to the CATIA program.
Choosing the tooling axis of the Bumper Design.
Then Creating a class B surface.
The surface of class C creation.
Joining the change Verify that the class A, class B, and class c surfaces are all closed.
Create a solid body from the surface by using the Close Surface function.
Finally, Perform the Draft analysis on the bumper design and finalised the plastic component.

Class A Surface:

Class A Joining_Method:

Here, the surface part is already closed because of the step. File format.
In Class A surface, must be closed.
If it is not closed or any invalid features are noticed the part will not going to generate.

Creating of Tooling Axis:

When creating a tooling axis by using the extract the surface at the center using normal to surface, point are chosen as inputs using the tooling axes that were established along the x and y-axes.
Select Insert > Axis System from the menu bar or click Axis System . ...
Select the point as shown to position the origin of the axis system you wish to create. ...
If you are not satisfied with the x-axis, for instance, click the X-Axis field and select a line to define a new direction for the x-axis.

Class.A & Class.B & Class C_Joining:

Draft Analysis:

The draught analysis approach is used to determine whether our CAD-created part model is capable of being manufactured given the draught condition employed.

Draft Analysis on Class-A Surface:

Enter analysis, feature draught analysis, and insert.
Align the compass and the tooling axis.
Click the surface to verify that it is within the draught values' permitted range.
The surface should be green, and the nominal input value for the column should be 90 degrees.
As a result, the draught analysis on the class-A surface was completed satisfactorily.

Draft Analysis on Final Part:

You can determine whether the part you drafted will be simple to remove using the draught analysis command.
In this kind of analysis, zones on the investigated element are identified by color ranges where the deviation from the draught direction at any given place corresponds to predetermined values.
