Description

This CNC design is my view of what can be done using Autodesk Fusion 360, an awesome cad/cam program.

It is a DIY 36" by 60" four axes, 10 inch Z CNC and table with optional vacuum assist clamping, it's a fully reversible assemble.

My hope is to replace the third car in the garage with a simple design and to make assembly as simple as possible. Overbuilding the three axes with extra rails and flying buttresses guarantees extreme stability and assured accuracy. The fourth axis is a lathe for simple turnings. This is an unfinish version waiting for input.

Anyone seeing possibilities please let me know.

There are many mistakes so feel free to point them out to me, and please comment.

Thank You

Mattias,
Thanks for the comment, I welcome your observation, I also have a two motor design for the Y axis. My intention in this design was to keep it simple and to over build so that the owner/ user will get more than expected for their money, I am aiming for a system that allow the user to create rather than troubleshoot.
The Y axis will be driven by a frame size nema 34, ClearPath® - Integrated Servo System(stepper killer), the X axis by the same and the Z axis by ClearPath® - Integrated Servo System, frame size nema 23. These motors have built in encoders so positioning is always being recorded, Each axis will be independently powered.
To get get a clear explanation of my choice of motors I look to the experts check the video below.

good job very nice, but do you relly think that one small stepper can drive y assembly all by it self? i think you need 2 steppers :)

Thanks Shane good luck to you, this is a good problem to have, I hope you have fun making great things .

Very Nice. I just purchase a small CNC machine with 4th axis accessory.
I am new to CNC so I have tons to learn.

John,
Thanks for the like and comment, this concept is in review, because I did a considerable deal of woodworking I understand exactly what you mean and how to incorporate it. In any case it would be done on the far end of the y axis. Designing the clamping system is the easy part, finding the funding is no fun. The vacuum clamping system is an independent option and would be completely flexible.

You could also build dovetails with this if you could take a piece of the center hold down railing and make it so that it could cut the dovetails on the end of the wood. You will need a clamping system which I don't believe would be too hard. You will also have to take the bottom out of the drawer part so that the part could be put into place. I see that you can move the A axis and with the addition of the dovetail this would be perfect. You would have to get rid of the drawer or at least make it shorter. I am not sure how that would work with the vacuum system if like you say there is one on there.

super idea i really like it shame its not up for download would love to look in more detail

Thanks for the comment and the like, I totally agree, my initial design had a triangular brace that I remove trying to shed some weight, I will reconsider replacing as I refine the design.

I like the style. If anything I think the Y-axis cross beam should be a little wider. You have the 'Z' incorporated in the side plates I could see how you could take advantage of that and bring the top of the 'Y' beam out into the 'Z'. Having center drive for the X-axis is very good to keep the structure from twisting under motor input. Don't forget the tool load will want to twist that 'Y' cross member also. The stiffer the better.
