  1. THRUST VECTOR Embrace Opportunity, Create Reality Western Sydney Regional Competition, Engineering Presentation

  2. THRUST VECTOR Embrace Opportunity, Create Reality CAD

  3. SELECTION OF CAD SOFTWARE ➔ OnShape ➔ Cloud Based, Everyone Can Access It ➔ Powerful Parametric Modelling ➔ Compatible With Other Programs ➔ Quality STL And STEP Exporting ➔ Automatic Saving ➔ Mobile Versions

  4. CAR DESIGN REQUIREMENTS ➔ Easily Assembled ➔ Lightweight ➔ Aerodynamically Streamlined ➔ Reduce Rolling Resistance ➔ Reduce Skin Friction ➔ Reduce The Low Pressure Void ➔ Comply With Regulations

  5. CAD APPLICATION ➔ 2D Sketches- With Dimensions/Constraints ➔ 3D Geometry - Extrudes, Revolves, Lofts ➔ Refinement - Fillets And Chamfers

  6. CAD APPLICATION ➔ Assemblies - Mate Connections, Orientation, Exploded Views ➔ Technical Drawings - Labelling, Formatting ➔ Rendering - Material, Lighting, Size

  7. CAD ORGANISATION ➔ Named Tabs & Workspaces ➔ Version Control ➔ Shared With Team Members & Teacher ➔ All Can Access Up To Date Files

  8. CAD BASED ANALYSIS ➔ Regulations Checks ➔ Volume/Mass Checks ➔ Virtual Cargo Placement ➔ Computational Fluid Dynamics

  9. CAD BASED ANALYSIS - CFD ➔ SimScale ➔ Works Directly With OnShape ➔ Justified Breaking Regulation T4.3 ➔ TVC2 had 0.575 newtons of drag, while TVC4 had 0.344 newtons of drag.

  10. THRUST VECTOR Embrace Opportunity, Create Reality CAM

  11. SELECTION OF CAM SOFTWARE ➔ Deskproto ➔ Produces G-Code Using STL Files ➔ Compatible With All CAD Programs ➔ Works With Multiple Types Of CNC Machines

  12. APPLICATION OF CAM/CNC ➔ Use Of A Machining Support Block ➔ Top/Underside Cutting ➔ Cut Along X Axis ➔ Took Off 2mm Per Pass ➔ Roughing Set To 0 ➔ Expanded Border To Make Sure The Edges Were Machined ➔ Roughly 30 Minutes Per Side

  13. CAR BODY MANUFACTURING ➔ Used Custom Jig ➔ Fitted Block To Jig ➔ Wedged Wood & Plastic To Stop Block Rotation ➔ Manually Position Cutter To Origin ➔ Load G-Code ➔ Start ➔ Repeat Above For Other Side ➔ Collect Rear Wings ➔ Glue On Rear Wings

  14. FRONT WING MANUFACTURING ➔ 3D Printing ➔ Load STL Into Software ➔ Configure Print Settings To 5% Fill Density & Export ➔ Transfer To Printer Via SD ➔ Begun Printing With ABS ➔ Warped & Ruined Print ➔ Used PLA Instead

  15. OTHER MANUFACTURING ➔ Cut Carbon Fibre Axles ➔ Put On Tether Line Guides ➔ Inserted Grommets ➔ Wheels Glued Onto Axles ➔ Sanded Sprues Off Wheels ➔ Constantly Weighed Cars ➔ Checked Cars With Manufacturing Tools We Produced

  16. TOLERANCING/QUALITY CONTROL ➔ CAD Design Accounted For Error ➔ Check Regulations Before Manufacturing ➔ Collaboration Between Design & Manufacturing Engineers ➔ Select Block With Most Optimum Mass ➔ Constantly Weighed Car ➔ Check Deskproto For Errors ➔ Check 3D Printing Software For Errors ➔ Run ‘Air Test’ Of Beginning Of CNC Process

  17. SURFACE FINISH ➔ Hand Sanding, To Remove Machining Marks ➔ Wood Filler, To Fill Dents & Divots ➔ Spray Putty/Primer, For Smooth Finish ➔ 2-4 Coats Of Paint, For Desired Finish & Mass
