  1. Computer Numeric Control (CNC) Manufacturing of CO2 Cars - An Overview Stage 1 - Prepare Final Design for Manufacture in Autodesk Inventor (Done by the students) Check design for rules compliance REMEMBER - Your part to be machined must fit within the dimensions of the standard Foam F1 Model block. The dimensions can be found in the Technical Regulations document. Add a machining reference plate to the 3D design. See details by clicking > Here Save your design as a .STL file in Autodesk Inventor and email to F1 in Schools Stage 2 - Submit a Manufacturing Request to YMC Find the online link (CLICK HERE). Fill the form and upload your car body (with reference plate attached) STL file. Manufacturing Costs: Standard machining = 350 Dhs per car (this includes all resources and full standard car wheel and axle kit) Additional machining operations = AED 50 each per operation. (Some designs will require additional machining to create detail on the top or bottom of the car that isn't accessible through standard side machining. Don't worry, F1 in Schools will check for this and inform you if it is required) Stage 3 - Computer Aided Manufacture using QuickCAM Pro (Done by the manufacturing centre) The 3D car model is converted to machining code. This is known as G-Code and includes all of the X,Y and Z co-ordinates that describe the profile of the car along with cutting speed, feeds and other instructions for the machine cutting operation to follow. Click the thumbnail below for an example of what this code looks like. Stage 4 - CNC Machining (Done by the manufacturing centre) Cars are machined on a DENFORD 3D CNC Router see this link for more information about these machines - http://www.denfordat...ompact-1000.pdf The Foam F1 Model blank is mounted in a special F1 in Schools Machining fixture Standard Machining, with the car oriented on its side commences via material being removed leaving behind the profile of the car design Here is a video of a typical CO2 car machining operation.... Stage 5 - We deliver the completed car body/s and wheel kits to your school! We will be developing more detailed classroom friendly resources that help explain the Design through to Manufacture soon. If you have any suggestions or comments, please reply to this post...
  2. Finished your car design - What next? Before making a request to have your design manufactured by Yas Marina Circuit there are some important things to do and consider: Check that the design complies with the Technical Regulations - most commonly students will design cars which are too long, too wide or too tall. It is important to check the maximum permitted car length in the regulations. Car bodies are not permitted to be as long as the actual Foam Model Block. This is because a portion of the Foam Block is held via a clamp during the actual CNC machining process. Ensure that no part of the body or other features such as wings which are to be made from foam block protrude beyond the block width of 65mm and block height of 50mm Wings designed to be manufactured from the foam block which are less than 3mm in thickness could break off during manufacturing and will be more prone to breakage during racing. The final step in Autodesk Inventor, in preparation for manufacture, is to add a manufacturing reference plate to the rear of the car. Instructions for this are presented below. The car body with reference plate added must be saved in .STL (stereo lithography) file extension format. This file format is required for compatibility for use with the CAM (Computer Aided Manufacture) software used by us to generate the machining code. ADDING A MACHINING REFERENCE PLATE Add the manufacturing reference plate | save as .STL | upload the .STL when submitting your manufacturing request to YMC F1 in Schools The final step before uploading your manufacturing request and completed design is to add a manufacturing reference plate as per the instructions document linked below. The reference plate is used during the CAM process to accurately locate your car model relative to the pre-machined C02 cartridge hole in the actual foam F1 Model block. Adding Manufacturing Reference Plate: AD Inventor-Add-reference plate guide.pdf EXPORTING THE CAR BODY INCLUDING REFERENCE PLATE AS A .STL FILE The following linked PDF explains how to export your design as an STL correctly. It is important to check this document as it explains how to export the file in the correct dimensional format. Autodesk STL Saving.pdf (Thanks to Jonathan Roberts from Repton School for sharing both of the above support files) If you have any questions or suggestions, please post them here by replying to this topic...

    What is QuickCAM Pro software?

    F1 in Schools - MAKE Used to convert your F1 in Schools car body CAD model into special code to enable manufacturing on a CNC router. QuickCAM Pro is an advanced, yet simple to use, wizard based CAM package, which is used to create cutter paths for machining 3D parts on a CNC milling machine or CNC Router. See pdf for more detail and contact us f1inschools@ymc.ae for purchasing enquiries. quickcam-pro.pdf
