– Converted the file format of machine profiles to CSV. You can load it into Excel to…
Is G-Wizard best for Big or Small CNC Machines?
I was recently contacted by a G-Wizard user who was unhappy that some folks on a forum thread felt our G-Wizard Calculator was only good for Big Industrial Machines and not so much for little routers. I told him I also hear sometimes from Big Industrial…
This week, we’ve added two new ways to find out “How-To.” First, for all the non-blog pages (for example, click the “Cookbook” menu), we have added Google Site Search. It will search all of www.cnccookbook.com as well as blog.cnccookbook.com. CNCCookbook is a huge site with several thousand pages on a wealth of CNC-related topics. If…
While most machining is 2 1/2 D, 3D Surfacing is still very popular. What’s the difference?
With 2 1/2D, it is rare that X and Y change at the same time as Z on the surface of an object. It can happen during cutting, usually due to ramping or helixing down into a cut. But…
I recently had a customer contact me about a material that wasn’t in G-Wizard’s Material DB. He had been told it was similar to a material that was there, but he felt the Feeds and Speeds G-Wizard was giving were a little too far removed from what the manufacturer was suggesting. Let’s use his problem…
I just updated the chapter on Surface Finish in our free Feeds and Speeds Tutorial. It now has over 40 great tips to improve your surface finish when Milling or Turning. Based on our recent survey on Feeds and Speeds, many of you consider Surface Finish to be one of the most important qualities you…
If you’ve been wondering how your peers approach Feeds and Speeds for their CNC work, wonder no longer. Our survey was very popular and we got well over 100 responses.
First, a little background about the respondees. On the whole, they were experienced professional CNC’ers:
59% had more than 5 years of…
Are your Feeds and Speeds Mild or Wild?
We’re running a survey to find out how our readers do their Feeds and Speeds. Our goal is to learn more about how to help and about what CNC’ers care most about when it comes to Feeds and Speeds. We’d love to have you take the survey,…
Nobody likes breaking cutters, but beginners seem to dread it the most. That little “tink”, the broken cutter tip flies across the room, and suddenly you’re unhappy. I’ve helped out a lot of beginners here at CNCCookbook, and in particular, I’ve helped diagnose a lot of recurring problems. A certain amount of it just goes…
Sometimes a quick video will get you up to speed quickly on a product feature–that’s why we offer G-Wizard University (accessible from the Help Page) for both our Feeds and Speeds Calculator and the G-Wizard Editor. But, other times, the video goes by too fast and you’re scrambling to get all the details so you…
Machining difficult materials like Titanium and Stainless Steel is a scary business if you own a smaller CNC machine. Even doing aluminum versus plastics and woods can be daunting. Our article on machining aluminum for CNC Routers is one of the most popular we’ve ever done, for that reason. But here is the surprising thing:…
I wrote the original G-Wizard Calculator in order to save myself time and get better results machining. I noticed I was hauling handbooks and tooling catalogs around, punching numbers into calculators, and eventually spending way too much time working through elaborate spreadsheets to get good results. There were things I was learning from the tooling…
Chilling your cutter with Liquid Nitrogen (LN2). Image courtesy of 5ME.
Have you ever heard of Cryogenic Machining? Better yet, can anyone reading tell us your personal experiences with it?
Cryogenic Machining is the process of using Liquid Nitrogen (LN2) as the coolant for machining instead of ordinary flood or mist coolants. It can produce…
I just uploaded new releases of both G-Wizard Calculator and G-Wizard Editor with some great new features in each:
For G-Wizard Calculator version 2.81, we added the following:
– Added Thread Mill Feeds and Speeds. Just choose the new Carbide Thread Mill tool from the Tool Menu:
– Added ER Collets to the…
Don’t you just hate breaking taps?
We’re putting together a Complete Guide to Tapping on CNC Machines that will consist of two articles in two of our Cookbook series. The first article, under the Feeds and Speeds Cookbook, discusses tap types, hole sizes, tapping heads, tapping fluids, and much more. It’s available now.
