Um Vídeo inspirador, um Homem Superior, Freemill à borla, e uma Fresa CNC

Ora, continuando como ontem na senda das Máquinas de Limar, com as quais qualquer um pode fazer peças porreiras, eis este Vídeo, de Allen Powell.
Aqui, não só se podem inspirar para esta máquina, mas para tudo o que achem na Net, e queiram duplicar, desde várias adaptações de Dremels, a máquinas CNC, ou não, por vós imaginadas, até às maravilhosas Máquinas de Reuleaux...
Porque é só fazerem um Molde em madeira, e derreterem Alumínio ou Zamak para 2 caixas de Areia de Fundição, e terminarem o trabalho na Oficina:




SHOP BUILT DIE FILER

Allen Powell

I found a photo on the the web of a old bench top die filer and thought I would try to make a copy. Having no plans I guestimated the dimensions and made a pattern, the most difficult part of the project. This project was good practice for making patterns, casting, and using my lathe and mill. The result turned out better than I expected.









Há gente que não se rende às Dificuldades, ou como diria Pessoa, tudo vale a pena, quando a Alma não é pequena.
Querem fazer uma Imressora 3D? 
Não têem quase nada? 
Pois vejam-se no exemplo deste grande Africano, que do Lixo, e 100 Dólares de Electrónica, fez uma Impressora!
É preciso é VONTADE!



African man makes a 3D printer from e-waste

Cameron Naramore

Not long after I joined the 3D printing group on Google+ there was a post made by a newbie about building a 3D printer out of parts from traditional paper printers and other electronics. There was a general consensus among responses that sounded a lot like a scoff. A few makers commented that while it was technically possible, it would be significantly more tedious to get working and the overall quality of prints would be subpar. Their response was based on the fact that firmware for RepRaps is written to communicate with off-the-shelf hardware. For instance, motors in paper printers don’t operate the same as the stepper motors that 3D printers use. 
For that reason, Kodjo Afate Gnikou bought stepper motors for his e-waste sourced 3D printer that he calls W.AFATE. He lives in Africa, pushing on the forefront of innovation. Much of the continent’s population is far from anything like the big box stores of the US, and the scarcity puts a premium on working with whatever is around. In Africa that’s heaps of broken computers and office electronics. For Afate that was a computer case, rails and belts from discarded paper printers and scanners, and the insides of a diskette drive. Purchasing the electronics and stepper motors set him back only $100.





 




Continuando no CNC, o Software FreeMill, continua a evoluír, como um Programa completo de fresa CNC, e vocês continuam a poder descarregá-lo à Borla, que é o mesmo que dizer, Grátis...
É bom!



FreeMILL 3D Milling package

FreeMILL is a fully functional 3D Milling package built on MecSoft Corporation's world renowned VisualMILL CAM package. With this product you will be able to import VisualMILL, STL, Rhino .3dm, VRML and Raw Triangle files, run full simulations on your part models and be able to output G code to your machine tool. The product comes with about 50 pre-built post-processors. This product is absolutely FREE! There is no time limit, part limit, post limit, or line of code limit in this product.
Available file imports include: VisualMILL, Rhino, STL, VRML. 



 

 






...Mas para o quê, ter esse Programa, se não tiverem uma Fresa CNC? 
Mais uma vez, um Engenhocas mostra-nos como se faz, neste Instructable, onde tudo vos é explicado, por este jovem e prometedor Engenhocas Holandês:




Building a CNC router

Benne

This instructable will show you how I built my CNC router. I hope you can draw some inspiration from my build and that this instructable will be helpful for your future projects. This instructable shows all the steps I went through in designing and building this CNC router.

The main thing I like about a CNC router, is that it is so versatile. You can use it as a drilling machine, a router, a saw, a mill and even as a lathe. Because my workshop is very small (it’s more like a shed), I didn’t have the  room for all of these tools, but I still wanted to be able to make very precise parts for different projects. That’s why I started to think about building a CNC router.

After doing some research I decided to design and build my own machine. It took my almost 6 months to build and design the machine from start to finish. Before starting the actual designing of the machine, I did a lot of research on the web. I recommend taking a look at the following websites: cncroutersource.com and cnczone.com. These websites will provide you with a ton of information and answer most of your questions on CNC related topics.
