5 3D Printing Clock Projects

Apr 10, 2014   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, Cool  //  1 Comment

Long time CNCCookbook readers will have come across my project-in-planning Astronomical Clock.  It’s one of those projects I promise myself I will be devoted to when my life is a little less busy (does that time ever come?).  Meanwhile, with a new 3D Printer on its way to CNCCookbook (just got the tracking notice yesterday, very excited!), I started wondering about making a clock with the 3D Printer.  Who knows, maybe this would be a good way to prototype some of the gear trains for my Astro Clock?  This also goes under the category of wanting to do something with CNC that my (nearly all) non-CNC friends would find interesting.  … Read the rest

Another GWC Release In the Can: Grooving/Parting, Peck Depth and MillTurn

Survey Time: How Do You Collect, Manage, and Use Tool Table Data?

Apr 7, 2014   //   by Bob Warfield   //   Blog, Manufacturing, Software, Techniques  //  2 Comments

Time for another survey.  I’ve had folks asking various questions for some time about how others are collecting, managing, and using Tool Table Data.  You know, like how long is that tool and how do I get that length into my tool table?
This survey is designed to collect all that information so we can see how the rest of the world does it.  Please give us your 2 cents and then you’ll be able to view the results:

Thanks in advance, I’ll report back on the overall results soon!… Read the rest

New 3D Printer Kit Coming to CNCCookbook Soon

Apr 2, 2014   //   by Bob Warfield   //   3D Printing, Beginner, Blog, CNC Projects, DIY CNC  //  4 Comments

We’ll have a new 3D Printer project underway here at CNCCookbook soon.  I just ordered the SeeMeCNC Rostock MAX v2 3D Printer Kit.  The Rostock is a “Delta” style printer, which has always intrigued me.  The kit purports to include everything you need except for a few tools and supposedly can be assembled in about 20 hours time.  The finished machine is quite good looking:

Rostock MAX V2 3D Printer…
The specs are impressive:
Over 1300 cubic inches of build volume (11″ Diameter by over 14 1/2″ height)
• US Made – high quality, laser cut, injection molded, and CNC machined parts.… Read the rest

Ballnose Cut Depth Musings for Feeds and Speeds in G-Wizard Calculator

Apr 1, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software  //  No Comments

I got a note from a customer who wanted to understand better why GW Calculator works the way it does with Cut Depth on Ballnosed endmills.  Specifically, he had a cut where he wanted to enter the full diameter of the tool, but he was being limited to effective diameter, which was smaller.  When depth of cut is less than the radius of a ballnose, a little thought and perhaps a visual shows that the full diameter is not engaged, but just the diameter out near the end of the ball.  Yet, he had a situation where the ball was down in a slot, and this is what was worrying.  … Read the rest

AtomicCNC: Revolutionary New 3D Printing Process

Apr 1, 2014   //   by Bob Warfield   //   3D Printing, Blog, Cool  //  10 Comments

3D printing is great stuff, but the reaction of many is that it is either a toy or at best only suited to prototype work.  Most 3D printing processes are too slow and too inaccurate to be used for full-scale manufacturing.  Until now.
I recently found out about an entirely new 3D Printing process invented by a Silicon Valley company called Atomic CNC.  Atomic are being very secretive about what they’re doing until they have all their patent ducks in a row, but I was able to get a preview of the technology and a few details.  Essentially, they have created a process that can 3D Print almost anything atom by atom (that pretty much guarantees any level of accuracy you might want) and at extremely high speeds.  … Read the rest

Foodini: 3D Printing Food in Your Kitchen for $1000

Mar 26, 2014   //   by Bob Warfield   //   3D Printing, Blog, Cool  //  No Comments

Are you ready for this?
Foodini has launched a Kickstarter program to sell their 3D Printer for Food.  The machine hails from Barcelona, Spain from a company called Natural Machines.  The earliest “investors” on Kickstarter will be able to get a Foodini 3D Food Printer for $999.  The Foodini retail price will be $1300.
The machine works by extruding food stuffs that are inserted in “food capsules” which are then placed in the machine.  Here is a shot of the machine and an extruder capsule:

Here’s the extruder capsule that it uses.  … Read the rest

10 Strategies for Managing the Feast or Famine Job Shop

Mar 24, 2014   //   by Bob Warfield   //   Blog, Business, CNC Projects, Manufacturing, Software, Techniques  //  3 Comments

Many, if not most job shops experience the “feast or famine” nature of the business.  They’ll be so busy for some weeks they can barely stand it.  Then suddenly they’ll be idle for a few weeks and wondering how to pay the staff.  It’s tough to run a business like that, and to a certain extent, it is the nature of the beast.  But there are some things that can be done, and this article presents some strategies to help deal with a Feast or Famine Job Shop.
1.  Use the Down Time for Training and Maintenance
Just because the shop isn’t crushed under the workload of a bunch of urgent jobs is no reason not to keep busy.  … Read the rest

More CADCAM Wizards for GW Calculator: ID Turn and Facing

Mar 21, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software  //  No Comments

I have just uploaded G-Wizard Calculator v2.36 to the install page.  It adds two more CADCAM Wizards for lathes:  ID Turning (boring) and Facing.  CADCAM Wizards have three advantages over just using the basic Feeds and Speeds applet in GW Calculator:
1.  They’re faster and simpler.  You have to tell the CADCAM Wizards a lot less information to get back an answer.  The information they use and provide is much closer to what your CAM software needs than just raw rpm and feedrate.
2.  They more optimal.  CADCAM Wizards uses some of the most sophisticated algorithms in the business together with the G-Wizard Feeds and Speeds engine to calculate a bunch of scenarios and pick the one best suited to your application.  … Read the rest

The Ebb and Flow of Customer Feedback for G-Wizard Software

Mar 13, 2014   //   by Bob Warfield   //   Blog, Software  //  No Comments

I feel very blessed to have so many wonderful customers who are so willing to share feedback that helps me make our G-Wizard software better.  We’ve had well over 25,000 machinists use the software to date, and so there has been a tremendous amount of “burnishing” of the software through the feedback of all you generous folks.  Feedback on the software tends to ebb and flow.  I get a big flurry of it whenever a bunch of new customers sign up.  One boss I worked for used to like to interview new employees after they’d been on the job for 2 weeks to ask them what they liked and disliked about what they saw going on.  … Read the rest

Precision CNC Machined Titanium Dice

Mar 11, 2014   //   by Bob Warfield   //   Blog, CNC Projects, Manufacturing, Products, Techniques  //  9 Comments

I love to hear from our customers what they’ve been doing with G-Wizard.  What’s particularly cool is when they’ve taken the time to really document an interesting project.  Here is James Dressman’s precision machined Titanium Dice.  A lot of work went into these, but the end result is a finely crafted set of dice:

The Titanium Dice and their presentation box…

You gotta love the idea of including an inspection sheet: that’s a true machinist’s touch!
James has included a series of videos so you can see how he did it.  I will embed them below, but you should subscribe to his channel to see what he’s up to over time.  … Read the rest

10 Cool Design Projects From Kickstarter

Mar 9, 2014   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

The exciting thing about CNC is you can make almost anything you can imagine.  For some, even more exciting is the prospect of owning their own business manufacturing products they have designed.  In the Internet Age that’s a lot more possible than you might think given the leg up in marketing services like Kickstarter can provide.  Kickstarter is a marketplace for not-yet-manufactured products.  The idea is to provide seed money that can be used to launch a product by offering the initial units in the Kickstarter marketplace.  Here’s a round up of 10 Cool Kickstarter Projects that are waiting for people to invest in their future as I write this.  … Read the rest

Help! G-Wizard is Giving Me a Higher Feedrate Than My CAM Software and Other Calculators

Mar 8, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software  //  2 Comments

I get mail with that kind of message every so often.  A machinist uses G-Wizard Calculator and it gives them a higher feedrate, sometimes quite a bit higher, than his CAM software or other feeds and speeds calculators.  The chipload is the same, and the formula to go from chipload to feedrate is simple, so they assume there must be a bug in G-Wizard.  In reality, the formula to go from chipload to feedrate is not so simple if you take radial chip thinning into account.
Radial Chip Thinning is a change in the geometry of the chips being formed as you take lighter and lighter cuts by reducing the Cut Width as a percentage of tool diameter when milling.  … Read the rest
