Suppose you’re hitting the upper rpm limit for your machine or you just want to run lower rpms for whatever reason.
Under “Change…” it tells you a little bit about what this accomplishes and suggests various things you might change to achieve your goal.įor example, to get better surface finish, it suggests you “Set Tortoise-Hare further left.” Of course that’s what the Tortoise-Hare slider is especially good at.Under “I Want…” are various things you’d like to achieve–longer tool life, faster cuts, better surface finish, making millions (oops, just kidding about that one!), and so on.If you click the Cheat Sheet Button, you get a popup Feeds and Speeds Cheat Sheet you can use to help you push G-Wizard in whatever direction you’d like: The Cheat Sheet Button: right below the Tips… I stuck it right below the “Tips” area, because it’s really extended Tips-style help: Thus was born the “Cheat Sheet” button starting with G-Wizard Calculator version 3.69 (just uploaded it). So, I started putting it together in Excel and then I had an inspiration: why not just build it directly into G-Wizard so it’s always handy? With the right cheat sheet, it can also open up your eyes to new possibilities you hadn’t considered. Then, I could direct people to it and help them solve their problems more easily. I’ve written a couple of different articles to try to help folks “hack” their Feeds and Speeds to do what they want, but I finally realized I needed a quick and easy Cheat Sheet. You can imagine what happens if G-Wizard wants to go slower and they just ignore it and run at much faster rpms–tool life suffers considerably. Either the spindle wouldn’t go as fast as G-Wizard suggested, or it wouldn’t go as slow (CNC Router users often run spindles with very high minimum speeds) as it wanted. Many times, people were trying to get around some limit they’d hit. Most folks are interested in tips for better tool life or surface finish.

Pros want ideas for how to crank things up and shorten cycle times.A lot of beginners want to know how to get G-Wizard to back off and make more conservative cuts.I take all the Customer Service inquiries here at CNCCookbook (except for just a few order-related ones), and I noticed a lot of people were asking a particular kind of question–they knew how to use the G-Wizard Feeds and Speeds Calculator in general, but they wanted to know how to influence its results to achieve certain goals. Recently, I decided to put together a cheat sheet to help folks with Feeds and Speeds.

And BTW, if you think that made the test easy, don’t I wish! The teachers all made the tests super hard knowing full well you had access to all that help. Now hang on, before you start thinking I was actually cheating, our tests at my school were all open book, open note, and usually unlimited time, so cheat sheets were allowed. Man, I got through college on my cheat sheets! You know, those little pieces of paper or charts where you cram in a quick summary of everything you need to know to solve some type of problem quickly.
