CNC Wood Router

A CNC wood router is a Numerical control tool that creates objects from wood. Parts of a project can be made and then assembled using a router to produce a complete project.

The CNC router works like a printer. Work is composed on a computer and then the design or drawing is sent to the CNC router for the hard copy. This outputs a 3-dimensional copy of the work. The CNC router uses a cutting tool instead of an ink jet.

 

The cutting tool is generally a router but other cutters can be used as well.

The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. CNC stands for computer numerically controlled cutting tool. This gives the computer a printer like ability to drive a CNC machine to make parts.

 

For engraving and general purpose cutting all that is needed is some material to engrave or cut on and an engraving or cutting tool bit.

 

A file of a picture or part has to be converted to g-code. Clamp the work piece down and then use the driver program to zero the CNC and run the g-code file. This will command the CNC to make the desired parts for you, quickly and accurately. Use it for all kinds of projects to make PCBs, gears, molds, etc.

The CNC Router is great for hobbies, engineering prototyping, product development, art, robotic education, and production work.

How it works

 

A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill with the following differences:

 

àThe wood router typically spins faster — with a range of 13,000 to 24,000 RPM

 

àLow end hobby grade machines typically uses smaller tools — typical shank size 20 mm or at most 25 mm. Professional quality machines frequently use surface facing tools up to 3″ in diameter or more, and spindle power exceeding 15 horsepower. Machines capable of routing heavy material at many hundreds of inches per minute are common.

 

àSome machines use smaller toolholders MK2 (Morse taper #2 – on older machines), ISO-30, HSK-63 or the tools just get held in a collet tool holder affixed directly to the spindle nose. ISO-30 and HSK-63 are rapid-change toolholding systems. HSK-63 has begun to supplant the ISO-30 as the rapid change standard in recent years.

 

A wood router is controlled in the same way as a metal mill, but there is a lot of CAM and CAD software like Artcam, Mastercam, Bobcad, and Featurecam specifically for wood routers.

 

Wood with different grain must be approached with unique strategies, and wood CAM software is less likely to need to have hog-out strategies than the metal ones. Wood routers are frequently used to machine other soft materials such as plastics at high speed.

Typical three-axis CNC wood routers are generally much bigger than their metal shop counterparts. 5′ x 5′, 4′ x 8′, and 5′ x 10′ are typical bed sizes for wood routers. But can be built to accommodate very large sizes up to, but not limited to 12′ x 100′. Most table routers use a three motor drive system (xyz) utilizing either servo or stepper motors that drive the router motor via a gantry system. The gantry system isolates the XYZ movement in the top part of the machine with a stationary table holding the workpiece. Many CNC metal mills have the cutter motor moving on the Z axis, and a table which moves in X and Y for added stability.

 

Many wood routers can run at machining speeds of 25 metres/min (linear) or faster with a few machines such as the Anderson capable of 40 metres/min, Onsrud capable of 86 metres/min.

Windows Vista

Last week I promised that I’d take a look at the new version of Windows that is currently under development, Windows Vista. Not wanting to disappoint, I will today be taking a look at the latest preview build (5231) that was released to beta testers a few days ago. Windows Vista (formally codenamed ‘Longhorn’) was originally envisioned as a minor upgrade to Windows XP designed more as a stopgap although as work progressed on the Operating System it took the shape of an all encompassing major upgrade. Let us take a look at some of the new features this Operating System will offer although please do bear in mind that the finished version is over a year away yet so obviously features are subject to change.

New look – Windows new look and feel is known as “Aero” which on suitably equipped machines will use the PC’s 3D accelerator to create a glass effect that will make the Windows visual experience deeper and more engaging. A downside to this effect is that it will require some pretty beefy hardware to create although on less powerful machines you will be able to go back to the classic Windows look

Security – This is being touted as the big improvement over previous versions of Windows and Microsoft is confident that they have truly got it right this time around. Windows XP if you will remember was riddled with massive security vulnerabilities when it first released and it took the release of two service packs to get it up to anywhere near a decent standard. Obviously there is plenty happening behind the scenes to protect you from security vulnerabilities but since the majority won’t be aware of any of this background work we should focus on the things that will make a difference in the way you use the computer day to day. Notable features include a firewall that will protect against unauthorised outbound activity in addition to the current ability to protect against inbound connections, parents will be able to set up parental controls to restrict what their children access and the OS should be able to prevent the installation of malicious software by using restricted access user accounts for day to day activities. The in-built e-mail client will provide anti-spam facilities as standard and Microsoft is planning to offer an anti-virus and anti-spyware subscription service although I would have personally liked to have seen this included as standard in the OS.

Internet Explorer – Windows Vista will include Internet Explorer 7 which is the replacement for the now four year old Internet Explorer 6. Although IE7 will be available for Windows XP eventually will be standard in Vista. As Microsoft is facing heavy competition from third party alternatives such as “Firefox” we should expect IE7 to be vast improvement although I think it is unlikely that they will think up anything original but just rip the best bits out of Firefox. For example, IE7 will support tabbed browsing and a built in RSS reader both of which Firefox has always included from the start. Security is again paramount in the new version of IE as it will include a protected mode to prevents Spyware and Malicious software from easily entering your system as well as a “phishing filter” which will protect you from fraudulent websites.

To summerise the new version of Windows looks as though it could be a worthy upgrade to the current Windows XP although we’ll have to wait until December 2006 to see everything that Microsoft has up their sleeves. Of course, there’s a lot more that I’d love to tell you about but unfortunately it’s difficult to cover an entirely new release of Windows in a 600 word article.
