You see this all the time on the Internet in the forums. Why can’t I just ask other experienced CNC’ers about their Feeds and Speeds? For an Infographic on Why You Need a Feeds and Speeds Calculator, click here. If you want to know more about other options, keep reading. If you’re ready to accept a Feeds and Speeds Calculator and want to move on and learn other things, click here. – By far the most popular option is to use a Feeds & Speeds Calculator such as our G-Wizard. Our G-Wizard Feeds and Speeds Calculator covers 60 variables! When was the last time you looked through 30 charts to figure feeds and speeds? You basically can’t do it, which is why: For example, a feeds and speeds chart is a 2 dimensional table. That data is important, but used by itself, it’s also loaded with limitations. – You can rely on data from the Tooling Catalog feeds and speeds chart. BTW, one of the reasons CAM does such a lousy job is it takes the approach of databasing standard cuts. After all, are all of the pockets you cut the same depth? There are variances in every job and if you’re locked into just a few standard cuts, you’re missing out on the possibilities. This method is pretty popular, but it sure is limiting.
– You can rely on standard cuts that have worked in the past or rules of thumb. You can’t hear somewhat bad and you sure can’t tell the difference between ok and really awesome feeds and speeds. None of that happens because you can only hear really bad feeds and speeds. If it did, you could buy “ear training” CD’s for machinists and Boeing would require you to pass a feeds and speeds by ear audio test before they would hire you. This requires quite a lot of experience and even though it has its devotees, it basically doesn’t work.
FASTCUT END MILLS SOFTWARE
Most CAM software does a truly lousy job with feeds and speeds. The reason is simple, and we uncovered in our CAM Software surveys. – Amazingly few use their CAM software, even though most CAM has provision for it. It’s pretty antiquated, especially for CNC applications. – About the same number use Machinery’s Handbook. Basically, it’s a lot of work for a lot of limitations.
This is the least popular for reasons I’ll discuss. This Guide is here to make that learning curve much easier for you!įor starters, it’s worth asking, “How do machinists determine Feeds and Speeds?” We surveyed our readership and here’s what they said: The answer, by a wide margin, was that Feeds and Speeds are the hardest thing to learn in CNC. We surveyed our readers to ask experienced CNC’ers what the hardest CNC concepts and techiques to learn were, and here’s what they said:įeeds and Speeds are the hardest thing to learn in CNC… How Do Machinists Calculate Feeds and Speeds? But they involve a lot of different concepts, which can make them hard to learn. Feeds refers to the feed rate at which the cutting tool moves through the workpiece material.įeeds and speeds are important because they’re the key to Longer Tool Life, Faster Machining Speeds (through higher Material Removal Rates), and Better Surface Finish. Speeds refers to cutting speed which is also the spindle speed in rpms. Speeds and Feeds are two of the most important cutting parameters there are. Why? Because feeds and speeds are the key to getting the best:įortunately, it’s not that hard to get great feeds and speeds with the right approach, and this guide will teach you how. If you’re serious about CNC, you NEED to optimize your Feeds and Speeds.
