First measure the height, width, and thickness of the frame. Then add all the measurements to the model in Fusion 360 by going to design - modify - change parameters. Then change the Frame Width, Frame Height, and Stock thickness to fit the correct measurements. To print this correctly change the frame size to be smaller than the piece of plywood to do that take a 1/4 inch off of each measurement.
After the measurements are taken apply coats of spray paint on the wood and let it dry
Next step is geneating to toolpath for where the CNC is going to cut. Do this by switching fro design to manufacture in the top left corner then Control G. Once you have done this there will be little green checks in your setup dropdown, go to --- actions ---- simulate with machine. This will take you to a preview where you can make sure all of your measurements are correct.
This step includes adding the appropriate bit to cut your design on the CNC machine Once imported into Fusion 360, you can run the job and verify that the bit will successfully cut the entire design.
Finally, right click your setup and click create NC Program and verify that your project is named and is on 1001. That completes the design process in Fusion 360, so save the design to your computer and email the file to the computer that is connected to the CNC machine.
Use painters or masking tape to put a layer of tape on the surface of the piece of wood that you are using to cut your sign on. Put a similar amount of tape on the base of the CNC machine, and add a couple passes of super glue to the tape on the CNC machine. Line up both the tape on the wood and base to be facing each other (this way the wood will stay in place while being cut). Access the computer connected to the CNC machine, select you file and precisely adjust the x y and z axis’ on the machine by using the arrow keys. Double check all settings and press play to run the job. Keep an eye on the job as it progresses and use the shop vac to clean up saw dust. When the job is complete remove the table.
First you need to create a new sketch then press create - project. Then you are going to select the surface you want to work on (the wood.) Next step is selecting the lines you want to use do this by hoovering over the line then selecting.
Right click the sketch you just created and press saved as DXF then name and save to Downloads.
Open Iliststor and import your DXF file make sure it is Original size (1x1 in.) Round your edges of the line you are cutting with a 0.25 tolerance. Make sure all of the lines are ungrouped and offest the path (-0.04.) Simplify your layers so that you have your cut line in its own layer.
Make sure all of the cut lines have a stroke of 0.001 and no fill. Next make sure you have seleted the correct printer and media size and send to the laser cutter.
Adjust the setting of speed, power, and frequency to the material you are cutting. (1/4 in acrylic, 1/8 in wood.) Set up laser cutter make sure material is in the corret place and run the job. Cut both acrylic for the "glass" part of the frame and wood as a backing.
Use the same line that you used to cut the acyrlic and wood and change the color using the Versaworks Color Library choose the Perf Cut Contour grey so that the printer cuts the photo out and send job to the computer and make sure it is loaded properly on the machine and print the photo.
Depending on how much room there is between the outside of the frame and the backing choose the appropriate clip to attach the backing to the frame.
Final Product:
1. In your own words describe the major steps to successfully go from a 3D Model to a CNC cut part.
First, take measurements and change the parameters; next, simulate the design to ensure it is right, export it as an NC file, then make sure all of the CNC is set up how you want it to cut, and then cut the frame.
2. What part of CAD/CAM did you find most complicated or confusing?
Make sure that the axes are set (X, Y, Z) and that everything is aligned properly, and make sure to align the wood in the correct direction. When I cut my second frame I did not have the (0,0) point set correctly which affected the sides of the frame.
3. What lessons did you learn along the way?
To make sure to double-check everything and check that I have followed all the correct steps and procedures.
4. What tools/software did you learn to use in order to create the artwork for your frames?
I learned how to use Illustrator and Fusion 360 and print things on the Roland and Laser Cutters.
5. Why did you choose the artwork that you did?
I chose to put a photo collage in my first frame and a picture of my homecoming in my second frame.
