6 Essential Information Resources for CNC Beginners

Aug 25, 2014   //   by Bob Warfield   //   Beginner, Blog, DIY CNC, FeedsSpeeds, Software, Techniques  //  1 Comment

I get a lot of notes from beginners with very basic questions, and many of the questions boil down to needing to understand the jargon of CNC or needing to understanding how the pieces fit together.  The vast majority of others need to get to the next level of detail and it’s not far out…

Trochoidal Milling Feeds and Speeds

Aug 17, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software, Techniques  //  7 Comments

I had a customer ask me how to calculate Feeds and Speeds for Trochoidal Milling with G-Wizard Calculator the other day.  G-Wizard is a perfect tool for finding these Feeds and Speeds, but first, what is Trochoidal Milling?
Trochoidal Milling is a High Speed Machining (HSM) technique that moves the tool in a shape called…

Adding New Materials to G-Wizard Calculator

Jun 28, 2014   //   by Bob Warfield   //   Blog, FeedsSpeeds, Software  //  No Comments

There’s a minor release out, 2.49, that I’ve just uploaded.  It primarily concerns adding some new materials:
–  AR400 and AR500 abrasion resistant steel plate.  Use this for buckets on excavators or it is also popular for making firearms targets.

What’s the Difference Between CADCAM Wizards and the Feeds and Speeds Calculator?

Jun 12, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software  //  No Comments

Recently a user of G-Wizard Calculator asked to understand better the difference between Calculator’s CADCAM Wizards and its Feeds and Speeds Calculator.  It’s a fair question as they look totally different and the CADCAM Wizards are so unique nobody will have had experience with anything like them before they tried G-Wizard.
Let’s start with the…

Estimating Cycle Times With Machine Acceleration: New G-Wizard Editor Feature

Jun 5, 2014   //   by Bob Warfield   //   Blog, FeedsSpeeds, GCode, Manufacturing, Software  //  2 Comments

An important concept that pops up from time to time is a CNC machine’s ability to accelerate.  Acceleration is often the real limiting factor to the machine’s motion, more so than absolute rapids speeds, for example.  In many real world g-code programs, the cutter may never get up to the commanded speed in some of…

May 11, 2014   //   by Bob Warfield   //   3D Printing, Beginner, Blog, FeedsSpeeds, Manufacturing, Products, Software  //  2 Comments

It seems an unlikely combination, but when you’re an entrepreneur, anything is possible.  Luke Colby’s company, Rocket Thermodynamix, makes parts for rockets.  I’m talking about full-on beautifully machined aerospace quality components.  Here is a typical example:

A pyrotechnic actuated poppet valve…
Yeah, I don’t know what you’d use one of these for either.  Maybe Luke…

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…

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…
