America: Built by the Little Guys, Not the Big Ones

Dec 22, 2010   //   by   //   Blog, Business  //  3 Comments

I correspond with quite a lot with friends in the Manufacturing world, as one of my big interests aside from software is building things.  Come to think of it, that’s really my interest in software too!
For a long time there has been a great hue and cry about the demise of Manufacturing in the US.  It’s been a victim of outsourcing, fewer and fewer new entrants to key careers like being a machinist, automation killing jobs, social pressures around whether blue-collar manufacturing jobs get the respect they deserve, the scarcity of good vocational programs, and so on.  On the one hand, the big manufacturing economy seems more and more hostile to its professionals. … Read the rest

And Now, the Secret RSS Link for CNCCookbook

Dec 21, 2010   //   by Bob Warfield   //   Blog  //  2 Comments

I will tell you the secret link…
I’ve had a lot of requests over the last year for an RSS feed for CNCCookbook. What many don’t realize is the ‘Cookbook reads like a blog, but I’m not using any blog software like WordPress to produce it. Each page is hand crafted in Dreamweaver. I’ve got a set of templates that make the process nearly as easy as using a blog, but alas, no RSS feeds. The answer is I need to switchover to some real blog software. Given the amount of content on CNCCookbook, that’s not easy. For example, CNCCookbook has not quite 500 pages.… Read the rest

The Results are in on the CAM Package Survey

Dec 17, 2010   //   by   //   Beginner, Blog, Software  //  15 Comments

Wow! We had a lot of folks participate in the CAM package survey. Thanks very much for your time!
And now it’s time for the results.
We’re dealing with two radically different groups here. It’s not really fair to compare an under $1000 CAM package against a full-featured package costing many thousands of dollars and up. At the very least it would give a pretty distorted picture of the relative appeal of these packages in the overall market. So I’ve divided the results into two camps based on the price of the package. This is not to say that the “Hobby” category is populated entirely by hobbyists.… Read the rest

Which CAM Package Do You Use?

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

I’m starting to do the research that is a precursor to building integrations between the G-Wizard software (calculator and editor) and various CAM packages. Towards that end, it will help me greatly to have some idea the relative popularity of the various packages since I won’t be able to build integrations for every package all at once.
If you have a spare minute, please take the CAM Package Survey. It’s just one question and I promise, it won’t hurt a bit!

G-Wizard High Speed Machining Feeds and Speeds

Dec 14, 2010   //   by   //   Blog, Software, Techniques  //  2 Comments

The G-Wizard Machinist’s Calculator has a new HSM Feeds and Speeds feature:

HSM Toolpaths can estimate your Tool Engagement Angle, tell you how much to slow down in corners, and tell you how much faster your feeds and speeds can be if your CAM program generates HSM toolpaths with constant tool engagement angles…
“HSM” refers to “High Speed Machining”, a collection of modern techniques designed to wring maximum performance out of CNC machine tools.
The HSM section provides several tools for dealing with the effects of Tool Engagement Angles (also called Cutter Engagement Angles). The TEA provides a means of measuring how hard a cut is working the cutter.… Read the rest

Machining an AR-15 Lower Receiver with G-Wizard

Dec 14, 2010   //   by Bob Warfield   //   Blog, CNC Projects, Cool  //  1 Comment

This is one of those ridiculously cool projects that brings home what I love about CNC and machine work: you can build anything!
Here is a video that details the software that Jim used to set up for his project:

Nice plug for G-Wizard at the beginning!
Lots of good stuff in the video about how he modified the original blueprints to customize his lower, and how he approached the CAM programming with some two relatively inexpensive pieces of software. The machining vids are also fun:

First stages to machining the AR-15 lower from a big block of 7075 aluminum…
Obviously the little CNC-converted mill can’t compete with a full-sized VMC for production, but if all you need is one lower receiver for yourself, it’s doing a fine job and moves right along.… Read the rest

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:

CNC Embroidery

Dec 14, 2010   //   by   //   Blog, Software  //  1 Comment

Somehow, I never tire of finding new CNC applications. It’s gotten to the point where it’s relatively cheap to create custom CNC controllers for odd applications, or in this case, custom CNC software. This is Khalid Khattak’s CNC Embroidery program:

The Future of Robots in Manufacturing

Dec 14, 2010   //   by Bob Warfield   //   Blog, Business  //  No Comments

I just watched a couple of fascinating videos on where robots are going and how that relates to manufacturing. They’re by Artificial Intelligence expert Rodney Brooks, who was also the man behind the iRobot robot vacuum cleaners. The nearly hour long series from Maker Faire 2009 can be seen here, but the interesting segment showing robots interacting with people can be seen in this YouTube video:

The Future of Robots in Manufacturing…
The technologies are fascinating. Apparently the breakthrough in machine vision has come from watching the relationship of objects to the background behind them. With the ability to construct a 3D model in the robot’s software coming from the computer vision, the kinematics needed to make the manipulator arm function are apparently also fairly straightforward.… Read the rest

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 your tooling manufacturer’s data sheets, that information is a set of recommendations to use as a starting point. The more variables it considers, the better the starting point you get, which is why many of our G-Wizard customer’s like the product so much. But, it’s possible to do so much more.… Read the rest

G-Wizard Picked Up in Tormach Face Milling Video

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

Check out the Tormach blog for a lot more information, but here is the video:

G-Wizard and SpeedyMetals play along with the Tormach Video…
It’s a cool video. That little facemill moves right along. I’ve had great luck with APKT tooling.  In this case, I wonder how the facemill would do with a little roughing work either peripheral milling or pocketing? If you’ve got a CAM program that can do rest machining (eliminate “air” cutting in successive operations) it could really bring down your cutting times.
The Tormach people are really excellent to work with. One thing I love about the company is they are constantly pushing the envelope and looking for new ways to solve problems for their customers.… Read the rest

Cutting Edge CNC Knee Mill From the 70’s

Dec 14, 2010   //   by   //   Blog  //  1 Comment

Well, in truth I don’t know if it was really cutting edge or is a 60’s or 70’s machine, but I think these old machines are a hoot:

Note the tape drive and funky looking pneumatic mechanism to run the quill for Z…
As cool as it is, I know guys with retrofitted knee mills running Mach3 that would probably run circles around it and their machines are not even going to get close to a “real” CNC. Note the pneumatic quill has some “canned cycle” options for dwell and so on:

Weird and wonderful!… Read the rest

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.

Tool Presetter…
Hopefully you’ll come across a thing or two of interest!… Read the rest
