Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
Design and Draft Analysis of Ribs & Screw boss
Introduction:
- The main goal of this project is to produce a plastic material for door trim components 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.
- Door Trim in the car is parts that contain switches and controls for different functions like Window control, Door lock/Unlock, Media, and Temperature controls.
Aim:
- This design aims to create Ribs & Screws & Plastic components 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 that has a specific 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, surfaces that will be hidden by another part when it is completed, or surfaces.
Design Methodology:
- Add the Door Trim class A surface design to the CATIA program.
-
Choosing the tooling axis of the Door Trim 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 on the Ribs & Screws are all closed surfaces.
-
Create a solid body from the surface by using the Close Surface function.
-
Finally, Perform the Draft analysis on the Ribs & Screws and finalize the plastic component.
Class A Surface:
Class A Joining_Method:
- 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.
- The part is fully constrained, use the join method and give distance propagation and join it all.
Creating of Tooling Axis:
- 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.C_Joining:
- In a process of joining A & C, it should be a closed surface.
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.
- Here, the component should be simple to remove from the panel dies (for sheet metal parts) or Mold (in the case of plastic).
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 3 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.
