Wheek 4:Computer Controlled

Cutting

In this week, we have learned how to use the computer cutting machinery, laser cutter and vinyl cutter.

Laser Cutting.

The laser cutter uses Corel Draw to input cutting parameters, and imports the image from inventor. The extensions used were dxf from Inventor and import to Corel. Provided all these tools, it was very hard to decide which one would suit me the best. I used Inventor from Autodesk on 2D or 3D I generated the 3D sheets and exported the file.

Parametric Design.
During thid week I designed a simple support for my phone with press fit.For the process I used fusion 360 with parametric design.

Fig 12. The model from the back. The file was exported as DXF to Ilustrator and then sent to the epilog 30 printer settings. The pieces have multiple ways of being assembled with press fit.

The Design.

I started drawing the sketch in the panel designs. This piece supports the DC motor on the squeeze machine.

The other part of the assignment with the laser machine consists in designing the flexible guard on Inventor.

The next pictures show the assembled flexible guard. This is used for the lemon hopper.

The kerf in my asigment was 0.2mm. I used plywwod.

Vynil Cutting.

The second part of the assignment for this week was Vynil Cutting. I found a picture that seemed easy to vectorize. In this case I worked with Corel Draw.
