Week 10 - Challenge 3 - Door Trim Lower with Engineering Features
DOOR TRIM LOWER WITH ENGINEERING FEATURES:
Objective:
To Create a door trim lower with the given class-A surface And create a B-Side Feature like 4-Way locator, 2-way Locator And Heat Stakes With Given Points. Then Perform Draft Analysis With Created Tooling Axis.
CLASS-A SURFACE:
TOOLING AXIS:
TREE STRUCTURE:
DESIGN APPROACH:
1) TOOLING AXIS.
First creating a dummy tooling for checking wheather its clearing are not. To create a Tooling Axis Extract A Part In Class-A surface And Creating a midpoint in the surface. and creating a line with the point in the Y-axis. Then perform a draft analysis with the created tooling axis and its clearing.(minimum draft is 3deg).
2) B-Surface Creation:
Inside a geometrical set, Offsetting a Class A surface 2.5mm inside. Check for any patch in fillet of the offset. Remove the Improper Fillets Using Join Command And sub elements to Remove. Then create the surface and Fillet it. Then Extrapulate The Outer Surface To Avoid Boundaries in final trim.
CLASS-B SURFACE:
3) C-Surafce Creation:
Inside a new geometrical set; Extract the boundaries of class-A surface. then Divide the extracted boundaries to Easily Sweep With Draft. The Sweep the Boundaries 3deg outward the Class-A To avoid Moulding marks in class-A surface. Then Join The Class A&C.
CLASS-C SURFACE:
4) Final Trim:
Inside a new geometrical set; Trim The Class-B And Class A&C Togeather Makesure That there is no boundaries inbetween.
CLOSED SURFACE:
5) Part Body:
Inside a new Body; Switch The catia to Part Workbench make the closed surface to body With Close surface Tool. then Perform A draft Analysis For Door Trim Lower Body With Minimum draft of 3 deg.
6) B-side features. (4-Way Locator & Heat Stakes).
Inside a New geomtrical set; Creating a Referance plane to sketch. Create a Sketch With Ref Plane In the Pre-defined Point as Given As input. Pad The Sketch with upto class-A Surface. Giving the Draft and Fillet to The body (draft=0.50Deg, Fillet R=0.25mm). Then Add The feature To Part body.

CONCLUTION:
The given Class-A Surface been Created as Door Trim Lower Part With Draft Analysis. The B-Side feature Has been created and Added To Door trim lower And Performed a draft analysis.
