RPM, Chipload, and Tool Deflection: A Surprising Relationship

Jul 26, 2011   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

In Physics, we have three ways of finding precise answers to questions:
1. We can conduct an experiment and directly measure the result.
2. If we have the math equations to directly deduce the answer, we can calculate it.
3. We can use computers to simulate the physical system and derive an answer by conducting…

G-Wizard Editor Version 2.00 is Available for Download

Jul 25, 2011   //   by   //   Blog, Software  //  No Comments

This has been a massive release nearly a month in the making, so I’m going to bump up a full 0.1 number to 0.200.
Here’s what we did in 0.200:
– Added an Axis Switch revision to make it easy to switch axes when programming right angle heads and such.
– Added an Adjust Words…

It’s Been a Productive Week at CNCCookbook for G-Wizard Editor

Jul 24, 2011   //   by Bob Warfield   //   Blog, Software, Techniques  //  No Comments

We had a productive week for G-Wizard G-Code Simulator and Editor last week. For a long time there have been 3 hard things left to do to finish the editor (and a couple of hundred fairly easy things, LOL):
– Finish up Fanuc Macro B Support
– Finish the lathe cycles like G71
– Optimize…

Alibre Acquired by 3D Systems: Is the Maker Movement Going Mainstream and Big Bucks?

Jul 19, 2011   //   by Bob Warfield   //   3D Printing, Blog, Business, Cool  //  No Comments

This is a fascinating development (hat tip to Dezignworks blog for putting me on to it). 3D Systems is a 3D printing company (think everything from personal Reprap-style extruders on up to commercial industrial strength solutions) that went public relatively recently. They’re showing nearly $180 million a year in revenue and a market cap of…

Tormach Personal CNC Lathe Castings

Jul 19, 2011   //   by Bob Warfield   //   Blog, Cool  //  2 Comments

The Tormach guys are really excellent people to deal with by all accounts. I already have a mill, so I have largely been a customer for some of their accessory tooling. I love their offline Tool Presetter “Tormach Tool Assistant” and their CNC Scanner, for example. Both very cool gizmos, and I’ll be writing more…

Swapping Axes for Right Angle Heads, Horizontal Mills, and Such

Jul 16, 2011   //   by   //   Blog, Software, Techniques  //  6 Comments

I ran across a request over on CNCZone for the ability to go through a g-code program and swap the axes. Apparently this is useful for writing programs for right angle heads or in some cases for converting a program from a vertical to a horizontal mill. I did a little research and came across…

CNCCookbook Receives Better Business Bureau Accreditation

Jul 16, 2011   //   by Bob Warfield   //   Blog, Business  //  No Comments

I’m proud to announce that CNCCookbook is now a BBB accredited company. BBB is all about protecting consumers, and insuring integrity and trust. They put it best themselves. Here are their words:
BBB sees trust as a function of two primary factors – integrity and performance. Integrity includes respect, ethics and intent. Performance speaks to…

HSM Toolpaths Chapter Added to Feeds and Speeds Cookbook

Jul 14, 2011   //   by   //   Blog, Software, Techniques  //  No Comments

I just finished posting the HSM Toolpaths chapter to the Feeds and Speeds Cookbook. If you’ve been wondering why those crazy swirly toolpaths are so popular, what the advantages for them might be, or how to figure feeds and speeds for HSM, check it out.

Comparison of the same pocket done with HSM and conventional…

Remember Stuxnet? Technology Being Imported to the US is Being Laced With Hidden Hacker Tools

Jul 11, 2011   //   by Bob Warfield   //   Blog, Business  //  No Comments

I’m not a huge fan of outsourcing manufacturing overseas, but now there is another reason to be concerned.

Remember Stuxnet? That was where the “good guys” (us presumably, though we won’t admit it outright) performed a little cyber-sabotage of the gear used to create Iran’s uranium-enrichment centrifuges for their nuclear program. Basically Siemens PLC’s controlling…

Which Software Product Should We Build Next?

Jul 7, 2011   //   by   //   Blog, Software  //  No Comments

We’re making good progress on G-Wizard Editor, so it looks like it will be out before end of year. Of course just saying that out loud probably jinxes the schedule, software being what it is, but it’s time to at least start dreaming about new products.

Give us your input on that dreaming. We’re running…

The latest installment in our G-Code Tutorial deals with Part Zero, Touch Offs, and Zeroing. In it you’ll learn what Part Zero is, the relationship of Work Coordinates to Machine Coordinates, and how to think about those concepts as you’re getting started with g-code. We’ll give you a recipe that saves a lot of time…
