G-Wizard G-Code Editor Gets a Little Touch of 3D Graphics

Dec 14, 2010   //   by   //   Blog, Software, Techniques  //  No Comments

Sometimes, it’s the little things that help out usability. I added a 3D rendering of the tool to the G-Wizard G-Code Editor and suddenly it’s much more obvious what’s going on in the simulation:

A Peek at the Upcoming G-Wizard Cut Knowledge Base

Dec 14, 2010   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

What’s a Cut Knowledge Base (KB for short) you ask?
It’s a way to dramatically enhance your feeds and speeds based on the real world performance of your machines, tooling, and shop practices. Look at it this way–wherever you’re getting your feeds and speeds inputs, be it a sophisticated calculator like G-Wizard, or directly from…

Part 2 of Tool Data Management with Tool Presetting, TDM Software, Chatter Management, and More

Dec 14, 2010   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

I just posted Part 2 of my two-part series on Tool Data Management. Part 1 was all about what kinds of data you’d be managing such as Tool Length Offsets.

Nothing New Under the Sun: Starrett Caliper Pressure Device

Dec 14, 2010   //   by   //   Blog, Cool, Techniques  //  No Comments

Kenneth Maxon, who runs the fascinating Max’s Little Robot Shop, wrote to tell me of some Starrett calipers he has which incorporate a precision spring loaded device for precise positioning. He describes it thusly:
I am lucky enough to have some older starrett calipers that perform phenominally and they use a similar mechanism. Inside the…

Tool Length Offsets and Tool Data Management: A New CNC Cookbook Recipe

Dec 10, 2010   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

Managing your tool length offsets and other tool data is essential for successful CNC work. This new two part Cookbook Recipe article delves into topics like:
– How Tool Length Offsets are used
– Pros and cons of positive versus negative tool length offsets
– The many flavors of touch offs
– Gage lengths and…

Candy Red Powder Coating

Dec 10, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Products, Techniques  //  5 Comments

I love the finish on aluminum IronMan from CNCZone is getting here:

Translucent Candy Red Powder Coat, not anodizing!
While it looks like a nice anodizing job, IronMan reports it is Columbia Coatings Translucent Candy Red. I have the impression from the post he chose it because he didn’t want to go to the trouble…

Special Purpose Robots

Dec 3, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool, Techniques  //  No Comments

We’ve reached a point where its actually pretty easy to build special purpose robots for various manufacturing tasks. For example, here is a robot that cuts off blocks of resistors from the rolls that feed pick and place machines. It’s used to put together parts packages for electronics kits (hat tip to MAKE Magazine for…

What’s the Optimal Monitor Configuration?

Sep 28, 2010   //   by Bob Warfield   //   Blog, Techniques  //  1 Comment

Too many!
As CNC’ers and machinists, we spend a lot of time in front of computer monitors. You’ve all seen multiple monitor configurations, and like me, I’ll bet you’ve wondered whether they’d help your productivity. If nothing else, these setups look cool as all getout, don’t they?

Gorgeous, but still too many?
But then I…

A Quick Course in Feeds and Speeds, Part 2 (Practice)

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

Here is Part 2 of the Quick Course in Feeds and Speeds which focuses on how to use the G-Wizard Feeds and Speeds calculator:
The video demonstrates the basics plus in depth walkthroughs of slotting, peripheral, and pocketing feeds and speeds calculations that show how the Cut Optimizer helps you decide on the best depth…

A Quick Course in Feeds and Speeds, Part 1 (Theory)

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

I’m putting together a quick video course in feeds and speeds for machinists. Here is the first installment:
Part 1 takes you through some of the theory. It’s a 10 minute video that covers things like chip thinning, relationship of cutter edge radius to chip thickness for best tool life, ballnose cutter compensation, and a…

QCTP Boring Bar Holders

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

I’m a firm believer that you can never have too many boring bars. If nothing else, this is an application where rigidity is always a problem as you reach down a hole with that long skinny boring bar. Shorter bars and fatter bars are more rigid, but they don’t work for every case. So you…

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,…

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…

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…

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…
