CNC Wing Ribs

by:QY Precision      2019-12-26
At the monthly meeting of our Experimental Aircraft Association, I told members that I could use the CNC router.
Soon a member asked me if I could cut off the wooden wing ribs.
The traditional practice is to make a fixture, stick hundreds of sticks and glue together and nail them together.
Considering that his project is double
Wing aircraft with 32 wing ribs, this is a very tedious time.
I said I \'d go.
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.
This project will be a good experiment.

Tooling BitsBaltic birch plywood-\"monthly or similarStaple gunX-
Acto, tool knives, some sharp pieces of sandpaper or foam (Things I need)
PatienceDust collection system Writing skills photography skills more tools bigger tools faster tools si got the blueprint (
(Actually white Cordyceps paper)to work from.
I stick the relevant parts together and trace the image to be cut on white butcher paper.
Then take it to a local building Copy Shop (FedX-Kincos will do it)
Let them make a digital file.
They also adjusted it to match the size given in the plan.
I was enlarged. 6%. (
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 people have steep learning curves that take 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! (
Load the file into my CAD program and do node editing, smoothing the external curves, or what is called in ship manufacturing, smoothing the lines.
Using the created circles at each intersection within the internal truss, I smoothed and cleaned the intersection, thus replacing the corner support plate that would appear when the traditional way was built. (
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 CADs 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. (
For those who want to know g-
The code has some websites that will tell you what it all means. (
The program has CAM output, so g-
The code is created and ready for a homemade CNC machine.
On our homemade CNC machine, it was a porter cable decoration router and since I chose the Baltic birch plywood, I chose a \"shank 1/8\" vertical mill.
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, just in case, there are all kinds of band aids and compression in our store.
I have some cardboard that I can use to make a trial cut.
Make sure that the parts you load on the machine are larger than the items.
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 cardboard (
Plywood later).
There are many dangerous opportunities here.
Cut cardboard/plywood larger than the item.
You want extra space to use screws, cam locks and even doublesided tape.
I used a DingTalk gun with \"DingTalk\" around the outer edge of cardboard and Baltic birch trees, blocking the direction of the router position.
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.
I powered the machine and the computer and turned mach3 on.
This is the interface of the actual translation g-
The router moves the code to the move.
Mach3 works with windows.
EMC is open-
SOURCE Linux version, then I loaded g-
Code for using a flash drive.
From a comfortable office to a cold and Manly shop, use wireless or anything you move your files.
Then I clicked the reset button.
Now I 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 or a separate numeric 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 .
002 will be in space, only halfa-
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 I clicked on the green button on the screen marked \"loop start.
Broken and broken. Yeah! ! !
If the cycle runs in a strange direction, I\'m ready to stop 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!
When the loop ended and the router returned to zero, I turned it off and removed all the staples.
I remove the waste part and vacuum or blow the dust so that the machine is ready for the next experiment.
It is almost perfect.
Several internal waste moves around in an uncomfortable way, with two truss bends (got too thin)
When the router side pushes to the side.
Finally, if the project is completely cut out of the scrap, I have a template that will prove useful.
So, I went back to CAD and placed some labels around each part. (
Labels are small pieces of wood that put all the different parts together.
They are smaller in thickness and shorter in length than plywood, with x-acto knife. )
During this run, I tracked it on a birch plywood with a cardboard template.
To ensure the safety of the material, I can place the staple food more accurately.
Plan B passed smoothly.
Now is the time to really look at the product.
Test it, measure it, and watch it carefully.
Go back to Step 4 and start planning if improvements are needed-C, or Plan-D, etc.
In most cases, it takes several tests and iterations to make it right.
I used a foam sanding pad to smooth all the surfaces and then clean them with it.
I then met with the aircraft manufacturer to get his approval.
There are only 31 left now.
Last summer, Mike and I started getting together at least once a week, or more, because we call it \"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.
