Tags: CNC, DIY, Machine, Motor Control, Robot, Robotics, Stepper Motor What is a CNC? The abbreviation CNC stands for computer numerical control, and refers specifically to a computer “controller” that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. In simple words, a CNC is a machine which is controlled by a computer, and used to fabricate 3D objects. This page will describe the process of building a CNC machine, from the design stage, the required materials and the process itself. Still confused? After seeing the movie, you must have understood how useful that kind of machine is for printing electronic circuit boards or manufacturing robot parts. But as I say – “If there’s a will there’s a way”.

You can download 3d cad files here if you are registered Specs. I'm afraid I don't have the space (or the expertise for that matter) to go into the fundamentals of CNC here but there is one websites in particular I found quite useful in my research. - A discussion forum which has a DIY machine section which is a wealth of knowledge ( direct link ) Machine Details: Cutting Head: Dremel or Dremel Type Tool Axis Details: X Axistravel: 14"Drive: Toothed Timing BeltSpeed: 60" minAcceleration: 1" per second2Resolution: 1/2000"Pulses Per inch: 2001 Y AxisTravel: 10" Drive: Toothed Timing BeltSpeed: 60" minAcceleration: 1" per second2Resolution: 1/2000"Pulses Per inch: 2001 Z Axis (up down)Travel: 4" Drive: Threaded RodAcceleration: .2" per second2Speed: 12" minResolution: 1/8000"Pulses Per Inch: 8000

Homemade Cathode Ray Tubes. By Nyle Steiner K7NS Oct 2007. Several Homemade Cathode Ray Tubes. This picture does not include the tiny 3mm dia crt. 3mm Outside Diameter CRT. This very tiny CRT pictured above, was made using 3mm outside dia. glass tubing. Cathode Ray Tube Details. The cathode ray tubes that I am describing here are crude and they are relatively easy to make at home. My reasons for building these homemade crt's should be obvious; certainly not to save money in building a TV set, but mostly because they emit a very intense fun field. In order to be satisfied that I had really made a working cathode ray tube, I had to build device that could direct an electron beam toward a phosphor screen, and be able to at least display Lissajous figures by deflecting the beam with magnetic coils. These cathode ray tubes are of the cold cathode type. The HV power supply for these crt's was improvised using the output of a Variac into the primary of a neon sign transformer. Standard Discharge Tube. Construction Details.

DIY CNC Router If you have any interest in purchasing a kit version of this machine please click the above button and complete the form so that I can gauge the level of interest. This instructable will show you how to construct a CNC Router that will allow you to cut 3-D shapes out of wood, plastic and aluminum using a standard hand held router. Recently I have noticed that more and more projects on instructables have involved the use of some sort of CNC machine, be it a laser cutter, 3d printer, milling machine, etc. I wanted to join this revolution of digital fabrication and start making my projects even better using these tools. I have designed this router to be very versatile and hope to also use this same machine as a 3-D printer and a hot wire foam cutter in the future. For those of you who already know about CNC routers here are the specs for my machine. This video is a time lapse of the assembly of the router, an hour and half condensed into 45 seconds.

CNC Machine Building - Design Components As a first project, you should not really be looking at anything more than a 3-axis machine, and keep axes below 1m, unless you like a challenge and have a big budget to play with. Limiting it to three linear motion axes on the X, Y, and Z plane also keeps these articles more straightforward as CNC machine building is a vast subject. If you have ever built a PC by buying all your components from an on-line store, then you will find building a CNC machine a very similar exercise, but rather than being a purely electronic based project, it has a mechanical aspect to consider too. So let us take a look at the various components that you need to use and incorporate in your design. Mechanical A typical 3-axis CNC machine consist of three perpendicular linear motion axes to move a working head to any point in 3D space. Framework, table, flatbed Linear guide rails, bearings, and supports Mechanical linear actuators (to translate rotational motion to linear motion) Electrics/Electronics

Repenser l’internet des objets (3/3) : Industrialiser l’internet Par Daniel Kaplan le 07/05/09 | 8 commentaires | 14,127 lectures | Impression Il n’existe pas aujourd’hui d’”internet des objets”, mais tout au plus une connexion en silos d’objets conçus et régis selon les règles les plus classiques de l’économie industrielle. La connectivité des objets et des espaces pourrait même signer la fin de la “parenthèse internet”, celle d’un réseau sans tête, sans finalité et totalement ouvert. Ce serait sans compter sur ceux qui, venant du monde numérique ou du design, s’activent dans le sens contraire : celui de doter le monde physique de certaines des propriétés de plasticité et d’ouverture qui caractérisent le monde numérique. Ca commence comme une conversation Que fait donc un capteur, se demande en substance l’enseignant et designer Julian Bleecker dans son “Manifeste pour les objets en réseau” (2006) ? Matière à réflexions Un autre designer, Usman Haque, a d’ailleurs décidé de les y aider. Des objets habitables Faisons-le nous-mêmes Arduino storia

Builders: first tests building a powder-based stereolithography printer: part 1 hi folks, i'm a bit sleepy, but i thought i'd post this while it's fresh: after seeing really interesting powder-based printer designs like this one, that place down a layer of powder then "print" a binding material onto it, i began to wonder (as others have) if we could build a similar setup using ABS powder and a laser diode to fuse the material together. designs like this have a bunch of benefits, including the potential to use the powder as it's own support material. (and, after a few weeks of tinkering with building an extruder for a second printer that *constantly* clogs, i think i needed a break to think about better days when we won't need to rebuild extruders, or hope we build working ones in the first place... ). my goals for this tinkering are to build things with common off-the-shelf materials wherever possible, and so I went searching for some form of ABS powder, as well as a laser diode. off came the cover i put some wire wrap leads on the diode look at that!

Modular Desktop CNC Machine by AJ Quick What is CNC? A CNC is essentially a machine that is controlled by a computer and can perform highly intricate maneuvers over and over again (similar to a printer). In this case instead of dispensing ink onto the paper, it uses a cutting tool to cut very detailed shapes into common materials like wood, plastic, & aluminum. It is a critical machine in any manufacturing factory, or research and development lab. We think it’s a tool that will be found in every workshop and home garage in the future. We want to make that future a reality! The Pitch In August 2010 we pitched an idea to University of Minnesota staff to create a challenge for five graduating seniors in the field of Mechanical Engineering. Our Project Our CNC Machine is 26” by 20” with a useable cutting area of 18” x 12”. The Prototype One of the benefits of being designed by engineers means that we have already scrutinized every aspect in the prototype of our design. The Rewards $10 Level. At this level we would love your support.
