I go through how I design a custom laser cut box in Fusion360. I use finger/box joints in the design that the laser will cut out to assemble a simple box. Some of the fingers are in a sketch, some are cut from other bodies. Here is the best method I have found to make a custom design to use with my laser cutter. I like the custom layout possible with this method. And the design is all parametric so it is easy to adjust quickly for varying material thickness or dimensions.

I like your use of parameters to calculate the tab sizes, but you should use the mirror tool, sketch projections, and combine tools to drastically reduce your design time.

Thanks, very useful video

I know that how I design the tabs may not be the most efficient. If you have any pointers on how to improve, I'd love to hear them. Thanks.

how do you get nominal dimensions and don't have problems with the tolerances of the laser cut machine?

Please Help! You have a really informative tutorial. My only question is why do some of my faces still show as squares? when I hover over them the tabs and broad faces seem to be separate, but when I look at the bodies they are solid and include the tabs (which they should). I computed interference and got not errors. My concern is that if I export this dxf as is, it will show a height dimension line segment essentially cutting off all the tabs on one side of the box. Fortunately, I can rectify this in a more familiar program but I want to do it in 360. It seems to have something to do with the parallel thickness lines I drew where the corners intersect... I hope I explained this properly.. Any advice would be greatly appreciated. Again, very good video.

If you're still seeing individual bodies, you can do a boolean join to get them to present as a single face. The way a dxf is exported should just be a projection of a single face, so if the line is there it should be easy to spot in the dxf and remove. message me and I'd be glad to do a review of your f360 design and try to spot the problem with you.

I'm stuck at 6:00 - I can't add the dimension because F360 is telling me "Adding this dimension will ove-rconstrain the sketch"

@TinkerWithUs 6 лет назад

Hi, sorry I was on holiday and am just seeing this today. So there is likely a dimension somewhere else in your sketch that is forcing the dimension. Usually you should only enter the dimensions on blue lines. Once a line is black, it is fully constrained either explicitly or via calculations based on other dimensions. If you think that a line should not be constrained (black) you can start to delete some constraints/dimensions to see which one is linked to the line you are investigating. message me if you still need some help, and maybe we can collab directly in f360 via a live review session. -John

I redid the tutorial and it works now. I think I was just new (this was the first tutorial I attempted with F360) so that explains why I got lost so easily. Did some of the Autodesk Tutes then came back to this. Thanks for the upload and introducing me to parameters.

Nice work! QQ: when I did a box like that my grooves appeared to be a little bit bigger (due to laser cut ~0.1mm), do you know how to make it fit perfectly so that the edges goes tough into each other? I know I can design it and check experimentally but do you know any other options?

@TinkerWithUs 6 лет назад

Hi, I have been using fusion for my CAM recently and you can do cutter compensation to adjust where the CAM paths hit. I've found that cutting on the vector works well enough for my needs, but if you want/need a tighter fit, you can look into the cuter comp settings to adjust for fit. Sadly the only real way to get a perfect fit is to experiment.

I'd like to know how one would add in kerf values for the laser.

@TinkerWithUs 6 лет назад

For kerf compensation I have usually just added in a small 'slop' factor to some measurements when defining them in the design. Then I can do test cuts and adjust this one parameter and have all joints change as needed. For my wood boxes, I don't find the laser kerf to be something that needs active compensation, your application may differ.

I Dont know about your laser but the china laser has that built in

@alienmoondudes8071 5 лет назад

can you show a video of you using fusion360 then using the laser cutter? I would love to see what we do after we have the .dxf file

@TinkerWithUs 5 лет назад

Yeah, sure I can do that. What workflow in particular are you wanting to see? I can show f360 -dxf-svg-glowforge right now. My k40 is down right now so I can't show the laserweb/smoothie workflow. going back and forth between the smoothieboard/laserweb and the original k40 control board/k40 wisperer.

Good tutorial. Couple of questions. Laying out the parts to cut. say in your box example you have 5 pieces. is their an easier way to lay them all out at the same time for cutting? also considering how they get layed out 1 for minimal material loss as well as considering what size material you have so they then can get cut from? Q #2 (the real important part) lets say your creating finger joints for material thats so called 3mm but intruth: once measured its really 2.87mm (choose any number its just an example) then also considering your lasers KERF. lets call that .05. (everyones is different, plus it changes depending on what your cutting) Now, in your model when you cut all your joints? Your box will fit together loose. (because of the loss of material ie kerf.) Any thoughts on how to compensate for that loss. when you have a part with lots of interesting points the kerf adjustment can get quite time consuming. thanks agin for the great post!

@TinkerWithUs 6 лет назад

Sorry for not replying sooner. For the kerf, I find that it doesn't really matter much with the laser. I do include a 'slop' factor that I have used to tighten things up, bunt in reality I usually just cut at the measured thickness and it works. In plywood designs the kerf difference is so small that the glue used in assembly easily fills the void. My acrylic boxes have had some larger gaps, but the solvent was still able to work. Make some test cuts and see how much it really matters in your application. But from my woodworking I've generally found that 1/64 or less is good for most things (miter corners excluded).

@TheSn1per 6 лет назад

TWU, Thanks for the response. and again loved the video. While I have adopted lots of your method I still need to be able to adjust for KERF. Perhaps your applications allow you to not feel the effects. Im not so lucky. HOW if you did want to adjust for it could it be approached? you seem to just have that feel for F360.. Im still trying to "GET IT" even with all the nights till 3:00am and tutorials making my head spin! being able to adjust the kerf would be a blessing! Thanks for the consideration. -S
