G-Wizard Custom Tool Cribs

Sep 24, 2010   //   by   //   Blog, Software, Techniques  //  1 Comment

I’m still busy making G-Wizard videos. They’re a real quick way to show someone a lot of information. The one I just finished is all about making custom Tool Cribs for G-Wizard:
Making a Custom Tool Crib in G-Wizard
Custom Tool Cribs can serve a lot of purposes. Since you can have unlimited Tool Cribs,…

G-Wizard Calculator Video Tour

G-Wizard Calculator Video Tour
I just uploaded a new video tour of G-Wizard to YouTube. It gives a brief overview of each of the applications included with G-Wizard. I really like video as a way of getting a quick intro to something without requiring a lot of tedious documentation reading. Here is the video:

Clever Binder Part Storage

Sep 24, 2010   //   by   //   Blog, Techniques  //  No Comments

There are never enough good ideas for organization, but I really liked this idea of using 3-ring binders for small parts storage I saw on the MAKE magazine blog:

Nice color code diagram on the outside of the resistor storage binder…

Plastic pockets hold the goodies…
There’s no end of things you could put in…

Deep Pockets

Sep 24, 2010   //   by Bob Warfield   //   Blog, Software, Techniques  //  2 Comments

Deep pockets are hard to machine. You’ve got tool rigidity problems with long tools to reach down deep coupled with chip clearance as the deeper the hole the harder it is to get the chips out of there. Couple that with thin walls and you have this part Eric Tate recently showed on the Yahoo…

Homebrew 250W CNC Laser

Sep 24, 2010   //   by   //   Blog, CNC Projects, Cool  //  No Comments

This is one bodacious project that I first heard about on the MAKE Magazine Blog. It’s creator has a site that tells the story of how he spent a total of $15K and 2 years to build it, but the results speak for themselves:

There’s the laser cutter in all of its glory…

I am Ironman!

Sep 24, 2010   //   by Bob Warfield   //   Blog  //  No Comments

Love the song, remember the old comics with fondness!
While I’m in a whimsical mood from having gotten my morning does of the Maker stuff (see below), I thought I should publish the result of my “Which Superhero are you?” quiz:

What machinist doesn’t want to be Ironman after seeing Tony Stark in action?…

Have You Seen the Maker Movement, MakerBots, and RepRap?

Sep 24, 2010   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, Cool  //  No Comments

I’ve know about the Maker people for a long time, but only recently subscribed to the MAKE Magazine blog, and it’s been a lot of fun. There’s a lot of homebrew CNC, but a lot of other projects too. Sort of a “nerds gone wild” sort of motif. Many of the projects are fascinating, but…

G-Wizard Has a Shot at the iPhone and iPad

Sep 24, 2010   //   by Bob Warfield   //   Blog, Software  //  No Comments

Amazing news this morning from Apple: they’ve dropping the rules they put in place that kept Flash off the iPhone and iPad.
I’ve had so many people ask if G-Wizard would run on iPhones and iPads that I had been really unhappy when Steve Jobs blocked Flash (G-Wizard is written in Flash). Assuming this really…

G-Wizard Gains Plastics, Composite PC Board, and Wood Materials

Sep 24, 2010   //   by Bob Warfield   //   Blog, Software  //  No Comments

Just finished up a 12 hour long day of number crunching to add wood, composite PC board, and new versions of plastics to the Material list for G-Wizard‘s Feeds and Speeds calculator.
G-Wizard uses an unusually detailed database for its Feeds and Speeds. This is one reason why it produces better results than the other…

Climb Milling a Must for Thin-Walled Parts

Sep 24, 2010   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

Thin walled parts are a real pain because the thin walls want to vibrate like a tuning fork. When that happens, you’ve got trouble, big trouble, and its name is chatter. I was reading a fascinating article recently that made the point that when milling thin walls, climb milling is a must. Because climb milling…

Deciding on Best Depth and Width of Cut When Milling

Sep 24, 2010   //   by Bob Warfield   //   Beginner, Blog, Software, Techniques  //  No Comments

I got a note recently from a G-Wizard user who wanted to know how to decide on best depth and width of cut when milling. It’s a great question. Most machinists, I suspect, use rules of thumb and habit more than anything else unless the situation dictates something in particular based on the dimensions of…

Cutting Chatter When Precision Boring

Sep 24, 2010   //   by Bob Warfield   //   Blog, Techniques  //  No Comments

I just came across what looks like a great blog from Criterion, the boring head people. They had a great tip to reduce chatter: make sure your depth of cut is greater than the radius on your cutter. It makes sense, and should apply when turning too. Here is how they explain it.
Consider the…

The Web is All About Sharing

Sep 24, 2010   //   by Bob Warfield   //   Blog, Business  //  No Comments

The Web is a Social Place. It’s all about Sharing your finds with others. While search engines like Google are great, and I use them constantly, often the real gems come via friends who tell me what they’ve found and liked. For a long time I’ve kept a CNCCookbook page on Delicious of all the…

Of Pallets and Parts

Sep 24, 2010   //   by Bob Warfield   //   Blog, Techniques  //  No Comments

I’ve always like the idea of pallets that can be set up with new parts while the CNC machine is working on another set of parts. Sort of like quick-change fixtures of a sort. You know it has to contribute to productivity, because when the machine stops you can swap the pallets real fast and…

Ballnose Surface Finishes

Sep 24, 2010   //   by Bob Warfield   //   Beginner, Blog, Software, Techniques  //  No Comments

It’s a small world, I guess. No sooner did I get done adding a section to my Turner’s Cube page showcasing Widgitmaster’s lathe-turned versions when I find him asking a question on CNCZone about how to calculate stepover to achieve a desired finish when profiling with a ballnosed cutter. As it happens, this function is…
