ME 340-2

Computer Integrated Manufacturing

- CAD/CAM -

Winter Quarter 2001/2002

 

From the relaxing palm beach with attractive fish to the vexing maze and the scary vampire teeth, from the daily-used items (trash-can, scissor and key-chain) to the mini-models of transportation tools (unicycle, car and helicopter), the creation and skills presented in this year’s ME340-2 design projects are just simply amazing.
