It seems to me that a machine capable of machining the mold and laying the tape would be attractive as it would combine 2 machines in 1, but you're probably right. I can't imagine trying to get one...

On our robotics team, we find ourselves machining a lot of 2" by 1" or 2" by 1.5" hollow aluminum tubing, 0.125" wall. This is all done on our OMIO x8. What about a 4th axis that the spindle would...
Gerry,
I knew that weren't many 5 axis machines that have been made and posted on this forum, but I did not know the number was as low as 5! Does this include all types of 5 axis? I feel like the...
I don't have a diagram of the exact setup I'm thinking, but it's similar to the chain fall described here:

I will work on producing a better...
Peter,
The chinese windlass is also known as the differential capstan, so the reduction is developed not by the ratio of the two spools but as a function of the difference in diameter between...
Peter,
I promise I will eventually 3D print a prototype and make a video about it. I have heard of Dyneema. There is another interesting actuator called a twisted rope actuator being used in...
RCaffin,
Yes, I would like to make many of my own parts. I'm interested mostly in the mechanical side, so I'm fine with purchasing motors and electronics. There's still personal value in making...
Thanks Peter, RCaffin, and routalot.
I am currently a junior mechanical engineering student. I've run and programmed a Velox 5050 CNC router when I was on my high school robotics team. I'm...
Peter,
I think the budget for this thing would fall in the $500 to $5000 range. It seems like it would be impossible to acquire anything more than the stepper drivers in the $500 range haha.

Peter,
That image from earlier was just a screenshot of something I made in Inventor, so I'm familiar with parametric CAD.
Isn't there something to be said for designing a tool to be as low...
Thanks for the help Peter.
1) My thought behind the crossed gantry was that it would be a different way to handle the loads of the highly cantilevered Z axis. A regular CNC router has a...
Absolutely. I'm a university student at the moment, so I think part of the use of this machine might be in developing that software side. That's not my focus, but I know of people who would like to...
Hello all,
I'm not sure if this is exactly the right place to post this but I wanted to get some ideas out there and get some feedback on them.
I've seen lots of CNC routers designed and built...
Peter, I was thinking that this inflection point could be handled without having to do a full retraction. You could coordinate motion between the A, Z, and X axes to sort of freeze the endmill in...

Yes, I do mean rotation about the X and Y axes. I had a sort of specific use case in mind that I will describe below that makes an AB head seem attractive.
Imagine you were to machine a cylinder...
Can you clarify what you mean? AB heads must exist somewhere, I just haven't seen any. Zimmermann sells an ABC head and in their advertisement they compare it to an AC and an AB head, so someone must...
I have been thinking about designing a 5 axis CNC router and I was wondering about designing an AB head rather than the standard AC head. I know, designing any CNC machine is a whole can of worms...

Thank you guys for the suggestions. It sounds like it will come down to making a prototype and seeing the specific kinks that arise.
Thanks again.
I am actually using wheels to drive the gantry. And the way that these segments need to be put together makes it necessary to have them on a table.
My tolerance on these plastic pieces is +/-...
Interesting idea with the timing belt. I considered that option, but it seems like it would be a little sketchy (and stretchy) over 50-60 feet, plus it's kind of expensive. This machine also does...
Hello folks,
I am designing a machine to make high altitude, zero pressure balloons. Each balloon is made up of 50 segments that are all heat fused together. These segments are almost 60 feet...
