6) Final results

  • Linked to the group assignment page
  • Reflected on your individual page what you learned of your labs safety training
  • Documented how you design your object and made your CAM-toolpath
  • Documented how you milled and assembled your final product (incluiding setting up the machine, fixturing, feeds, speed, etc)
  • Describe problems and how you fixed them
  • Including your design files and hero shot of your final product
