Sorry Troy, I respectfully disagree. I've been in this business over 40 years and you wouldn't be the first person I've known that misunderstands the fact CNC machines make just about every single thing you touch in your business. That ventilator is in fact an offspring of the major equipment that made it. A very tiny part of a CNC machine is in fact that ventilator. I guarantee you that whatever little program that operates the bellows in that ventilator a properly programmed CNC mill could do, inhale exhale multiple bellows timing everything. Furthermore, give me any windows based CNC mill and any sensor that ventilator has and the machine could be programmed to process the sensor information to adjust the real time program the same way the ventilators doing it. Trust me, any windows based CNC mill is that ventilators daddy. Fully adjustable to work anything you put in front of it. Its a computer capable of running multiple axis's to do whatever that ventilator can do and more.

I am an amateur CNC operator in the sense that I built and run an Avid Pro 24x48” w spindle and Mach 4 and cut wood acrylic and aluminum sheet on it every day (taught myself parametric design on Fusion 360 and do tool paths in it).

I am also a US board certified, and practicing critical care physician.

I agree w Troy’s points above. Although obviously a repetitive and cyclic movement can be programmed on a CNC machine, that is a minor part of a modern ventilator.

Sorry, I know exactly how a ventilator works, different modes and functions that could all easily be provided on the table of a windows based milling machine, a spindle attachment could move among and operate them all. Don't forget how quick feeds can be. The exact same pressure sensors could easily be programmed to do exactly what they do on a respirator. Zero problem.
The mill wouldn't be just pushing up and down on a bellows, that would be super easy. A spindle attachment could easily move between pressure switches, bellows, whatever the sensors telling it to do. Pressure and volume controlled exactly the same as a ventilator. I seriously have to say I'm surprised you can't see this considering your background.
This could be accomplished quite easily actually. Any good machinist could do this. No ifs or maybes about it.Guaranteed!

A normal cnc machine control can not do anything that a ventilator can do and would be dangerous for the patient to even think it could, I build CNC controls and have been in the medical industry and know people that have worked for the companies that make ventilators, tkevan is correct it's not even close to what is used to control a ventilator

Your thoughts are in the right place in helping but this is not going to help

Dyson has just built one that can be mass produced and it has been rejected at this point

James Dyson designed a new ventilator in 10 days. He's making 15,000 for the coronavirus outbreak

Alok Sharma, the UK business minister, said Friday that ventilators made by Dyson and other suppliers will need to meet regulatory requirements before being used by the National Health Service.

Any windows based cnc control could be modified to except data from the same respirator sensors in a ventilator. It could easily be adapted to whatever movements you require. Sounds like many people on this forum have only basic surface knowledge of their machinery. It is a robot, it just needs someone that knows what their doing to tell it what to do. Far better than nothing if your life needs a ventilator.

No it could not you are repeating yourself, just basic knowledge you say then go to it and show everyone how to build one, talk is of what can be done does not get it done, so take some action instead of wasting your time here

I thought you where being helpful now you are being ridiculous with your posts,

Ventec is working with GM and GM are almost up speed, GM will make parts that support the building of a ventilators

There are more than just ventilators that are needed, if you want one so bad go to Ebay there you can buy one

Most of all we would love to see what kind of franken machine you come up with

Wow, off the rails because you lack the ability to understand your CNC is a programmable robot. This post is for anyone with the necessary brain cells in Italy to see they have an option to get a ventilator up and running in a life or death situation. Not for someone that thinks that you should buy it on ebay or all the other scenarios where ventilators are, or may be available in the future. lol You need to go back and read everything very slowly.

Your posts are extremely ridiculous and off the rails. You're obviously dealing with limited knowledge on this topic, yet you say it can't be done. It can, you should be ashamed of yourself for attempting to thwart a viable option merely because you alone can't understand. This could save a life. You need to take a course in robotics.

The challenge is up to you now, show us what you can come up with,( No more talk ) and see how far you can get with your Franken machine with now your CNC control or your Robotic control, I will give you a heads up neither control will work to control a Ventilator good luck [/U] (nuts)

I hear Dyson have said it'll likely be 6 months before a design of thiers gets passed in the UK so that's that for them I reckon.

Black market will use / sell them if they have the accessories to go with them

Yes correct the problem is not only the machines it is all the tubing valves and masks that are also required so the accessories that are needed to go with a machine to make it usable are a problem as well, and that will depend if it is invasive or not invasive as to what is required for each person being treated

A basic machine itself could be built around a high quality PLC it could be programed to do the most basic of breathing requirements, but could not be used for intensive care, this is the part that most people don't understand

So in the USA GM has started manufacturing parts for one company Ventec nothing they make will have to be passed, Ventec will be making all the parts that are already approved so any manufacture could be doing the same they just need to team up with a ventilator manufacture and make all the none critical parts mostly Injection molded and extruded parts are needed and stands Etc

If I had the molds required even for just one part I could have my molding machines running 24hrs a day as they can run unattended
