A few months ago, I remembered a drawing tool that I played with when I was a child-a lung volume map.
Searching for a local store will only lead to a small and pathetic alternative to the plastic I remember.
So the inspiration and ideas for this project have grown.
I have a background in making exhibits from museums, zoos and nature centers.
I have been asked to build the most amazing thing for 25 years.
No problem with this project.
Including the design of the heart; 1)
Big enough to fill an 8.
5x11 sheets of paper, 2)
The holes will fit-
Sharp sharp, 3)
\"Appearance\" will be industrial equipment --like, 4)
Made of wood, not plastic.
It should be durable considering that the child will use it.
List of things/materials and equipment you need: computer gear generator program (
EMC or similar drawing program ((
Router or contract manufacturer -(www. 100Kgarages. com)
Nail gun or ironing board-
Acto, utility knives, some sharp Baltic birch plywood-5 layers or similar sandpaper or foam blockages for Beta testing (Things I need)
PatienceDust collection system Writing skills photography skills more tools bigger tools faster tools (
Computer-aided design
There are so many design programs ((
Some are free, some are not.
Try a free download or trial download and take some time to evaluate their abilities.
Make sure you see what they can import and export.
This is very important for moving the drawing file to the CAM generator (
More information later).
High end, there is a steep learning curve that takes a while to adapt.
Low end and free stuff has been getting better.
Check out Sketchup (free)
Use ruby scripts that are allowed to be output in. stl and . dxf formats. Sweet! (
Downloaded gear generator (
It\'s easy to spend $26.
It can draw any number of gears inside or outside.
You can add the spoke to any number and it will be output in.
A useful format.
It\'s fun to play and easy to play.
After generating rings, Gears of various sizes, I saved the file and imported it into my CAD program.
I need a hole in the fine-
The tip to be placed is sharp.
After measuring the diameter of the shark tip.
15 \", I started to place holes on the spokes at different distances from the center point of each gear.
Obviously, in order to reinforce the narrow wood next to the hole, I need to expand that part of the speech.
I created a series of circles and placed them centrally on each Sharpie hole to enhance the wood.
Next, I removed the extra vector and cleaned up all the images.
So I drew the vector diagram of all the parts with the smallest paper size.
I then cut the 5\'x\' Baltic birch plywood into the required size for 16 \"x 21. (CAM -
Computer-aided manufacturingSome drawing (CAD)
There is no way to get g-code from them. G-
The code is a language that defines where the router must go to perform the tasks you have in mind, generated by CAM.
Some CAD have CAM but they tend to pay for itfor types.
For those who use CAD programs that don\'t have this feature, you have to find a separate program to do this.
Here are some links. (
Those of you who want to know g-
The code has some websites that will tell you what it all means. (
Our homemade CNC machine is a Porter Cable decoration router.
It will accept handle tools of 5/32 and 1/8 with Chuck.
Since I chose the Baltic birch plywood, I chose a vertical mill with a \"handle 1/8.
That means it\'s powerful (thicker shank)
, The bottom is square and the cutting width is 1/8 \".
Our router has only one rotation speed, the speed of 25 linear inches per minute reaches the maximum, so our only control is the depth of every cut it passes through the material at an inch per minute.
Install this bit into the router you have before turning on any machine.
Be very careful. they are very sharp.
I don\'t know, but there are all kinds of Band-Aid and compression products in our store just in case.
Most of the time the test runs, I will choose a blue or gray insulation board.
This time, I took a small piece for testing.
This allows me to see how many things I messed up in CAM and CAD.
It also creates a prototype to check if it really works.
Finally, if the project is completely cut out of the scrap, I have a template that will prove useful.
Make sure that the parts you load on the machine are larger than the items.
Also, I put a cardboard under the material to protect the bed of the machine.
It looks obvious, isn\'t it?
Also, it is in the right direction on the X and Y planes.
I never made that mistake.
Stable plywood.
There are many dangerous opportunities here.
Cut the plywood bigger than the project.
You want extra space to use screws, cam locks and even doublesided tape.
In this case, I used wooden strips and screws in my first run and nail guns and nails on the outer edge in my second run.
No matter which method is adopted, one does not want the highly rotating router bit or the router itself to hit something hard and unyielding.
Some very interesting results will happen and you really don\'t want this experience.
Least of all, you might be in g-
Code and get the rest of the cut
Worst of all, there are high-speed rail debris flying around.
This brings us here.
Da-OSHA favorite time themeda… SAFETY.
Here we go, ignore the danger that this is in your own.
OK, condensed version :----Ears -
The CNC machine is very loud.
I like to wear noise canceling headphones and play my favorite music in the background.
Don\'t be too loud because you want to hear it gently while the machine is running, give you a head --
Any questions. ----
Eyes and faces-objects flying do sometimes come from machines and it is better to protect them.
I used a mask. ----
Breathing-all materials create some dust during cutting.
At least filter shielding for non-use
Toxic wood and cardboard, better for medium fiber boards and plastic. ----(
Manufacture or purchase a dust removal system, if possible, to keep smoke and dust to a minimum.
This is our next project after this competition.
I wish I had done it earlier. )(
Finally, the fun began.
Power up machines and computers, turn on Mach3 or EMC.
These are the interfaces for actually translating g -.
The router moves the code to the move.
EMC is open-
Mach3 is the source code for the Linux version and can be used with windows.
Next load g-
Use a flash drive, wireless or any code that you move files from a comfortable office to a cold and Manly store.
Click the reset button.
Now you can move
Run the router to locate the 3D coordinates (X,Y and Z)
Determine the size of the bit by using the numeric keyboard on the keyboard.
You really want to fire that thing.
You have been doing it for a while.
You\'re impatient.
Well, at least describe me sometimes).
But we have to get off at the right foot, or inches, or a few inches per thousand.
X, Y, and Z must be zeroed.
Most of the time, this will be the most important thing. lower-
The top left corner of the picture.
Be slow and careful not to insert the drill bit into the material or hold-down clamps.
I found that the tool part was really broken and expensive.
Once over zero, gently lower the drill bit above the top of the part.
I then placed a plug-in under the drill bit and moved it down very slowly, just touching the plug-in. Using .

Hair on the material.
In this step, you remember not to turn on the router. Right?
Now is the time to turn on the router and start cutting the sequence from mach3.
Just like your mom used to say, \"Don\'t forget your gloves,\" remember something safe.
Turn on the router first.
Then click the green button on the screen marked \"loop start.
You were cut. Yeah!
If it takes off in a strange direction, click the stop button and be ready to close it.
Remember the motto of the computer ,(
And dangerous machines attached)
Just do what you ask them to do, not what you want them to do.
If all goes well, watch and enjoy this moment.
It was great for me and I used to cut all these items by hand.
This is a wonderful world!
Turn off the router when the loop ends and it goes back to zero.
Then remove all the clips, screws, DingTalk, or whatever. have-
Hold the material firmly for you.
Pick up this piece and be surprised.
Remove the waste part, vacuum or blow off the dust so that the machine is ready for the next wonderful project.
It\'s time to really look at your product.
Test it, measure it, and watch it carefully.
Get a sharpie and see how it works.
If you think it needs improvement, go back to Step 3 and start planning --B, or Plan-C.
I\'m really lucky this time.
In most cases, it takes several iterations and tests to get it done.
I\'ll go through this part because I\'m sure most of you will have some experience in this. I used an X-

Grinding pad, I polished all the surfaces smoothly, especially teethhi cleaned the gears with air and brush.
I don\'t think the stain will improve the look.
Finished with spray polyurethane.
In any case, do it outside and put on a mask.
Allow complete drying.
Give this game to some kids.
Take some paper and a lot of color sharp and let them get it.
See what they do with it.
After observing for a period of time, break the quarrel and let them share;
Think about any improvements or changes in the design you might want to implement.
Maybe redesign the teeth for a better fit.
Maybe change the shape of the ring to some extent.
Keep these spirits flowing and see what happens.
After all, all these jobs are real games.
Last summer, Mike and I started getting together at least once a week, which we call \"man time \".
We do some ideas, hacks, projects, or repairs with things in the store.
This leads to some clever solutions using rather strange materials.
The interaction between us was very interesting and we started to invite others to join our \"club \".
So my store is occupied by a manufacturer. I love it.
About this time, Mike introduced me to structures.
Com and I were hooked.
He also brought his own CNC router.
We started and ran it and have been submitting some interesting items for this competition.
Our manufacturer club will continue to explore the vast world of CNC cabling.
We came up with the idea of a lot of backlogs by winning the PRS Standard 96-48-6 ShopBot .
Our homemade CNC can cut up to 31 \"x 21\" with a cutting speed of 25 \"/min.
4\' x 8\' tables and 300 \"/Min will greatly improve our ability to produce prototypes, develop and improve designs, create larger projects and test 2.
Then move to the full 3D engraving.
