When I was first asked this question one thing came to mind. “Boy, machines sure use a lot of cutting fluids, oils and electricity.” Perhaps these areas that can be improved. That is how I got interested in hydrostatics’ a technique in witch a low viscosity fluid is injected at high pressure on a specially design bearing surface to reduce friction. Hydrostatics have been implemented on hi precision machines such as grinders and wafer slicing machines. But if tuned for friction in less precise machines can they save you energy? Hydrostatics also have the advantage that they do not ware out and do not use oil base lubricants, perhaps there are savings there. And finally upgrading machines with the latest controls and motors which are currently very efficient and can be sized smaller given that you may have lest friction in the system will also help.

Now this merits some research and some number. When I get around to crank this I’ll post it. I will be like carbon footprint equivalent for a CNC machine. And this gets me thinking; maybe it’s not about the net saving but about the intention. All good things start with intentions and there is no telling where this can lead us. Maybe, this can be a key ingredient that can get young people interest in manufacturing; it can become a differentiator.

Any thought on the subject ? What other areas besides machine are there?

Is Open Source Hardware about Invention or Innovation?

The reason I post this question is because I got thinking about my project and what is hip in the manufacturing world. I was reading this piece in technology review on work that Nicolas Correa has been carrying out and it makes we wonder.

1-Should Open Source Machine’s come from a standardization of designs and components that can be source competitively hence reducing cost and allowing people to get exactly what they need?

2-Or should it stem from bringing to users new technologies that traditional manufactures are not bringing to the market or are simply too expensive?

In the first point we are looking at more innovation than invention. If this is the case we should focused our efforts at getting creative with what we already have. We are not inventing anything fundamentally new but playing with the configuration, the assembly interfaces, machine architectures, sourcing. In the second case, we are about bringing new inventions, new designs for spindles, and new construction materials to the machine design and shop floor. It comes to mind the use of all ceramic and composite constructions coupled with active viscous shear damping and hydrostatic linear and spindle bearings for smooth, high speed, low friction, highly damped movements.

Perhaps it’s a step approach, first we get the Open Source designs with standard components working in ways that have new value to users, and then with this experience under our belt we start introducing new technology. Come to think about this make sense to me know, we got to learn to walk before we can run.

Now what is of value to you? Do you have everything you need in the shop?
What’s missing? Where would you like to innovate, or see innovation happen?
