Process. Today is the day to go big. Given my final project requires a physical drawer. I think I'm gonna take this opportunity to try to design and do it.
Create CAM --- Thanks to Anthony, A comprehensive video about how to create CAM step by step.
First, I took sometime to learn the history of CNC and how this rounded tool is so powerful and also at the same time, creates a series of problems. This is where the fusion add-on tool came in. This add on allow people to use up to 60 days for free and create their dogbone feature on all kinds of design patterns.
Dogbone referene on fusion page: HereNifty Dogbone referene on their website: Here
So I went ahead and designed my drawer in fusion 360. I used the dogbone feature to create the joints.
One really helpful video I found on youtube really helped me understand the whole design process.
Parametric Design. Tried to avoid using any hard coded number for the dimensions of the design. My feeling so far is such practice can be powerful, but one does have to pay more attention tot he constraints added to different parts. One missing constraint can cause the whole thing out of shape if parameters are changed in the future.Rearrange the pieces on a planeSelecting drill size and Adding tabsSimulation after the work's complete to review the route.Dogbone tool is very easy to use. Set the diameter to 0.62cm(0.25 inches)CNC Preparation Stage, Fix the OSB(Oriented Strand Board) to the tableShoots plastic nails, connect with airtank.Safety Note: 1.Never aim it at people; 2.Don't come too near the gas vent of the gun. For the standard OSB, 7 rows of 7 nails per row would do.Calibration required before it starts.Cutting Done!Use brushless cutter to cut the tabs on partsWith about an hour of filing, all the parts fit perfectly. I noticed it was a bit bigger than I expected, after going back to fusion, I realize I was really typing in the number for cm when my fusion was set to inches.That's why the whole thing is 250% of what I intended on every dimension 😂3D support that goes between the bottom and the upper panel.
Fun to watch the cutting while the computer goes through the G-code.
This drawer is one essential part of my final project.
