- Assignment 03
This week is dedicated to the use of machines working in 2D.
I designed a parametric photo box using Solidworks. I have parameterized so that I can easily change the dimensions of the box.download Photobox 64,3 kB (.sldprt)
For the next step I exported the sketch in dxf.download Photobox 27,6 kB (.dxf)
I imported the dxf in Silhouette Studio, set A4 landscape as paper and converted the dashed lines into continuous lines.
The machine had mounted two heads, one for the cut and one pen. So I set the red lines for cutting and the blue lines for drawing.
The machine is equipped with an adhesive sheet on which I affixed the paper sheet to cut (A4, 200
Afterward I placed it against the wheels of the machine. Before proceeding I moved the right-hand wheel for adapt it to the size of the adhesive sheet, the difference between Figure 5 and Figure 6 can be seen.
To insert the sheets I pressed charge (CARICA) on the screen. Now everything is ready for cutting.
From the screen visible in Figure 4 I pressed send (INVIA). The cut was successful.
This is the final result after I removed everything
Following the pen lines I bent the sheet to give it the desired shape.
And this is a photo test with a miniature painted by me.
Using the same process, but without using the adhesive sheet, I also made a vinyl sticker using a file made last week with Inkscape.
Also with Solidworks I designed the project and parameterized it with the thickness of panel "t" and the tolerance for the joint "i".
The design is unique and divided into 4 different bodies, two of them, which I mirrored, are repeated twice for each segment of the snake.download RubikSnake 347 KB (.SLDPRT)
Separately I exported the faces in DXF and with Rhinoceros I made the table and add a 0.1mm
kerf with Offset command. Since the program I used later to send the file to the lasercut
is always Rhinoceros I saved in its native 3DM format.
For completeness also attached the DXF.
On the computer connected to the lasercut I opened the 3DM file, cloned the segment a few times and in the Properties I made sure that they were all defined as By Layers to prevent lines from getting thick.
The program sees the lasercut as any printer so I did File -> Print to open the CAM interface.
In View and Output Scale I clicked Set... to set the virtual workspace. Then I opened the Properties to set the cutting parameters.
In Pen I reduced the cutting speed to 2.0 mm/s.
In Advance I set the Position Mode to Relative to start cutting from the top left corner of the drawing starting from the laser position in the machine.Therefore I clicked on OK and Print to send the file to the lasercutter.
The lasercutter is a SpiritGLS by GCC with a 960x610 cutting area. I placed a 3mm MDF panel under the machine head and from the control panel I pressed Auto Focus to adapt the table top to the thickness of the material to be cut.
The head from which the laser comes out can be moved by hand, so I placed it in the top right corner for panel and, after closing the protective cover, I pressed on Start.
You can see the laser cutting through the protective cover.
This is the result once the machine is finished.
This is the assembly sequence I followed.
All the pieces fitted perfectly without the use of glue, but for safety I put some vinyl on the outer sides.
This is my Rubik's snake with 14 segments!
