Ardenum,

The surface plate is my main reference point/surface and work table. I plan on using quick change fixture plates on top of my surface and mount pallets and vise for workholding on top....

Ardenum,


Its hard to see from the picture of the model, but the plate would be installed after the UHPC was cast. I am planning on casting 3 threaded inserts into the surface plate cavity, this...

Nice clean work

Pete,

Thanks for the input. I agree, on the CAD time. I'd hate to try and dispose of one of these castings if I made a design error.

Speaking of going in circles. I came up with another design....

Pete,

I own a CMM, although some of the components for this build will exceed the capabilities of my CMM. I may be going back to the drawing board with this machine. I agree, some of those tools...

Pete,

I thinking making it from more than 3 components (base, 2 columns) would not be a good idea, as I would be tolerance stacking. Every milled flat joint surface would have some error and I...

Ardenum,

What size box are you thinking of for being "big and rigid"?

Pete,

I would not say I have a lot of disposable, I would like to be able to see a return on my investment down the...

Ardenum,

If you are refering to the X axis saddle, is 12" center center on the X axis and 7.5" center to center on the Z axis rails

Can you please explain, I don't understand what you mean.

Pete,

I'm trying to get the main components designed/placed, then I can tweak them slightly after to add way wipers and what not.

This is how I plan on attempting to build the machine,

1....

Pete,

So I've been playing around with the model a bit. A big part and must of this CNC project is the ability to have large tool magazines. I have 30,50,70 on the ones I have access to and even...

Pete,

I do plan to cast the base upside down. I have pallet jack and can have access to a forklift across the street that can flip it over for me. I am trying to figure out how to work out chip...

I prefer SW, but I use Fusion daily because everyone I'm doing projects with is using it. I've been using it for the past 6-7 years and while you can generate the same 3D models, it always takes me...

Jonny,

Looking good. How do you plan to keep the top of the Y axis rail mounts coplanar?

Also, how do you insert large photos into your posts?

Pete,

Its a pretty easy and decent CAM software to learn, it has several features that are neat, but I don't like making sketches/modeling/assemblies in it. Modeling in 360 is like hammering nails...

Pete,

I do like that Makino machine design. I'll see how I can incorporate some of that into my design.

So after spending some time rethinking this project, I think this may be the only way I...

ardenum,

Thank you for the Moglice book.


Pete,

Thank you for that explanation and clarifying the difference for the epoxy application. Attached you will find the joint that I plan to use...

Pete,

Moore's book is great, I've read it years ago but will read it again, I am sure I will come in handy. Thanks for looking up a ratio. I'll come up with some CAD models to demonstrate how I...

If I was to cast this in multiple pieces, I would not want it to come part after. So I should use a paste epoxy instead of a liquid epxoy right? I'll research the subject a bit more

How would the joints look? I'm a bit confused, I don't understand how can you assemble two surfaces together that are not flat and not introduce stress into the structure?

A picture or a link...

Pete,

I think I can only afford to make it in one piece. Making it in multiple pieces would add to the cost significantly because I would need a lot of machining for the mating surfaces.

I...

Ardenum,

I plan on making it from precision grout. I am going to play around with some of the Sika 212 grout Pete mentioned in a few post ago, before I attempt to cast this beast.

Pete,

I...

Pete,


I spent some time looking at some bases and this is what I came up with for my mineral casting. Still needs some revision and a little weight loss? Its at around 3 tons

Pete,

Please excuse my ignorance with cement. I thought it was like silicone, once that thin film starts to form over it, you can no longer lay more silicone on top of it.

I was looking at...

Pete,

So the Sika 212 is suitable for machine bases? If so I guess I'll get myself some bags, make a mold and try to cast something. How would one go about mixing large quantities of this? I can...

Ardenum,

Thanks for the links to the videos on designing with UHPC. I'll look over the build thread and the videos and comment when I process everything. I am limited on space, so the raised...

Pete,

Hahaha. I thought the same thing after I designed it. Welding nightmare.

Regarding UHPC, is the precision grout you recommended not a type of UHPC? I would also like to know if there are...

Pete,

Yes, very far away from making chips. This was another option I was considering, a tube base (still a rough design) that was one piece or could be made in 3 pieces, but I am not sure if its...

I was planning on welding that frame, that is mainly made up of 1/2" flat stock and 3/8" steel sheets. Like I said, I have no idea of how to make the frame anymore, just coming up with random designs...

This is the latest and greatest idea. I don't even know what route to take anymore. haha
