What If Dyson Made CNC Routers Instead of Vacuum Cleaners?

May 14, 2013   //   by Bob Warfield   //   Blog, CNC Router, Cool  //  10 Comments

Here’s a cool CNC Router made by Michael Warren who is the James Dyson Fellow at the Royal College of Art’s InnovationRCA.  It’s a portable CNC Router and his web site is Grow CNC.
Check out the video (can’t go wrong with Johnny Cash on the soundtrack):

CNC 4th Axis Basics: Routers and Woodworking

Apr 30, 2013   //   by Bob Warfield   //   Blog, CNC Router, Techniques  //  5 Comments

This is the 4th part of our 4th Axis Basic Series and it covers the use of a 4th axis for a CNC Router and when woodworking.
For the most part, the principals of 4th Axis use with a CNC Router on wood are much the same as the more metal-focused articles that have come…

Hexapod Robotic CNC Router Walks to the Site of the Work to Be Done

Apr 22, 2013   //   by Bob Warfield   //   3D Printing, Blog, CNC Router, Cool, DIY CNC  //  8 Comments

This is a cool little Hexapod robot I came across:

The resolution on the 3D face looks pretty darned good.  I’m imagining combining this sort of technology with sensors that let it precisely locate itself via some optics.  You’d have a ‘bot that you could turn loose to carve large areas with 3D relief carvings,…

Introducing Our New CNC Router Blog Category

Apr 14, 2013   //   by Bob Warfield   //   Blog, CNC Router  //  2 Comments

Blog Categories are like channels that bring together articles with related topics.  You can find our list of Blog Categories along the left column.  We’ve got a bunch of them to help you zero in on the kind of articles you’re looking for, and we just introduced our newest one:  CNC Routers.  Go there to…

You Can’t Find Optimal Feeds and Speeds in Charts, Handbooks, or the Seat of Your Pants

Apr 3, 2013   //   by Bob Warfield   //   Blog, Business, CNC Router, FeedsSpeeds, Techniques  //  No Comments

I see a lot of interesting discussions about feeds and speeds out on the Internet.  There are people that think you can get good feeds and speeds just by reading manufacturer’s charts, by ear, from their CAM program, and through a whole host of other shortcuts.  Some say they’ve had enough experience as machinists that…

What Now: My CNC Won’t Go Slow Enough or Fast Enough?

Mar 15, 2013   //   by Bob Warfield   //   Beginner, Blog, CNC Router, DIY CNC, Software, Techniques  //  No Comments

It takes a complex bunch of math to properly calculate Feeds and Speeds under all conditions and to get anywhere close to good answers.  There is a whole lot more to it than the basic equations everyone learns that claim to relate surface speed, chipload, rpms, feedrates and the like.  Unfortunately, those equations work reasonably…

Build a Mechanical Iris

Mar 12, 2013   //   by Bob Warfield   //   Blog, CNC Projects, CNC Router, Cool  //  No Comments

G-Wizard customer Lepton Heavy Industries has a neat blog post out about building a mechanical iris.  I don’t know why, but these darned things have always fascinated me.
This particular project uses a laser cutter to make the iris out of Baltic Birch, and it is based on a ShopBot CNC Router article by Chris…

Making Tool Trays From Cutting Board

Jan 20, 2013   //   by Bob Warfield   //   Blog, CNC Projects, CNC Router  //  No Comments

I love working with the plastic used for cutting boards–typically HDPE or High Density Poly Ethylene.  For cutting boards you usually see it in that milky white color.  I buy a few any time I see them on sale just to use as raw material for other projects.  Here’s some photos showing their use for…

Donek Drag Knife Adds Versatility to CNC Routers and CNC Mills

Dec 27, 2012   //   by Bob Warfield   //   Blog, CNC Router, Cool, Products, Techniques  //  No Comments

Came across this unique drag knife from Donek Tools and thought it was very slick:

The video demo shows some pretty amazingly sharp cuts being made at high speeds because the knife orients itself.  It takes ordinary utility knife blades and comes in 2 sizes.

Donek founder Sean Martin invented the Donek Drag Knife to…

Why Use a Single Flute End Mill?

Dec 23, 2012   //   by Bob Warfield   //   Beginner, Blog, CNC Router, FeedsSpeeds, Techniques  //  4 Comments
when to use a single flute end mill

There are a lot of strange beasts out there in the cutting tool world, and a lot of physics that are not obvious.  For example, many machinists will know that more flutes means more productivity, but that certain materials, like aluminum, require fewer flutes–usually two or three.  If that’s the case, when would it ever…

Jared’s Cube: Baffling and Beautiful

Nov 12, 2012   //   by Bob Warfield   //   Blog, CNC Projects, CNC Router, Cool  //  3 Comments

If you like Turner’s Cubes, perhaps Jared’s Cube will appeal:

I found these quite by accident via Google. Aren’t they cool?
Something similar would make a neat CNC router project.  I could imagine one like the last photo but done so the layers alternate light and dark woods.  If you’ve done something artistic with your…

CNC Router Tip to Reduce Pullout from Wood

Oct 23, 2012   //   by Bob Warfield   //   Blog, CNC Router, FeedsSpeeds, Techniques  //  3 Comments
Engraving wood plaques

I came across this neat tip over on to reduce pullout when engraving or milling wood.  The idea is simple: just spray a sealer like laquer on the wood to give it a little more support.  Here’s a nice cleanly engraved plaque done using this method:…

INFOGRAPHIC: Why You Need a Feeds and Speeds Calculator

Oct 13, 2012   //   by Bob Warfield   //   Beginner, Blog, CNC Router, FeedsSpeeds, Software, Techniques  //  1 Comment

A question I hear fairly often is, “Why do I need a Feeds and Speeds Calculator, aren’t the manufacturer’s recommendations good enough?  Here is an Infographic that walks through the limitations of Manufacturer’s Recommendations vs Feeds and Speeds Calculators like our own G-Wizard:

G-Wizard Adds Machinable Wax Feeds and Speeds for Lost Wax Casting, Jewelry Making, and Prototyping

Oct 9, 2012   //   by Bob Warfield   //   Blog, CNC Router, FeedsSpeeds, Software, Techniques  //  1 Comment
Machinable Wax

Machinable Wax is a really neat material.  It can be used with a Lost Wax Casting process to make jewelry and all sorts of other things.  I’ve done Lost Wax Casting before, and it is a simple process that yields good results.  The Wax is recyclable if you keep the shavings–just heat to 290F and…

MIT Students Create Hand-Held CNC Router: You Gotta See This!

Every now and then you see one of those inventions or products that makes you do a total double take because you realize they are game changers.

Three MIT students,  Ilan E. Moyer, Alec Rivers, Frédo Durand (left to right in the picture), have created a game changer for CNC Routing and woodworking.  Their invention…
