Assessment1 - The Bowl

Process

Step1: Use laser cutting make the template of the bowl - a consist of a series of concentric rings and also a 'radius gauge'. Mark all the disk on a aluminium sheet.  
Step2: Cut around for 230mm disk. I did this part in a big hurry. So that the edges are not very perfect, I found that the defects was more obvious as the aluminium stretching. Although it was a small failure, I accumulated experience from it.
Step3:  Hammer the sheet alone the disk marks on an plywood slab and sandbag, the material shrinking and stretching to make a bowl shape. The aluminum sheet is softer than I thought,  the process feels like making a sculpture. Strength is not only the key of shaping the bowl but also understanding of mechanics of a bend. 
Step4: Use English Wheel with the radius 155 hammer and dolly to smooth the shape. This process can help to make the radius more accurate and even.

Assignment2 - The Fuel Tank

Stage 1: In Group of 10 make the 1:1 Fuel Tank Template  We chose the Custom tank for a CB550, and used Rhino to prepare the Digital Tank File Stage 2: 'Slice' and Laser cutting  We used Autodesk Slicer for fusion360 to 'slice' the Digital fuel tank. for the Template we decided to   make 13x15 slices. The software automatically layout the slicer, but for saving time and material we rearrange the layout in Illustrate. Then, we were ready to do the laser cutting. The automatically generated slice file has innumerable line segment, so it still took us a long time to finish all the laser cutting. Stage 3: Assemble the template We glued all the template to make it more stable. Stage 4: In the small group we divide the tank into three parts  Prepare the aluminium sheet ,used A3 paper to measure the size of material I need and the and marked the shape and fuel tank contours. Then used Guillotin...

Reflection Summary  Before studying this course, I thought that is really hard to create a curved or reverse curve shapes with out mechanical technique, or 3D printing technology. I would like to know how students in the industrial design discipline make their products especially with metal material. In architecture discipline there is few chance to use metal to make model, but models like Frank Gehry' Walt Disney Concert Hall have to use metal sheet to show the movement of the form and reflective materials. From this course I learned how to make templates and use the templates to create shapes with metal sheets with different,  and the characteristics and capability of shrinking and stretching. And a well prepared template and tool choice can achieve a better result. In the project Reverse I was quite inspired by the beautiful shape. I didn't have time to actually make a design and model, but I made a image to show my idea of reverse roof. I think I can try...
