You’re going to set up a cut in Fusion 360 by selecting your Toolpath (for example, Adaptive Clearing) and then giving Fusion 360 all the parameters it needs to create that Toolpath for you. This is a traditional workflow you could use with any method of finding Feeds and Speeds–whether you use a Feeds and Speeds Calculator like G-Wizard or your own Excel spreadsheet, this is how to approach it. Workflow #1: Traditional Feeds and Speeds I’m going to give you two simple workflows to use with Fusion 360 and other CAM Software that will give much better results. They’re just the defaults for various popups anyway. They are one of the few CAM vendors that realized the old tabular model gives lousy results, and it’s been a real competitive advantage for them as a result. If I were you, I would only use these Tool Tables as a means of describing the tool being used and not in any way as a means of determining Feeds & Speeds.īy the way, one of the most highly rated CAM packages, Solidcam, has a special feature called “ iMachining” that’s very similar to what you’ll get with these workflows. The Tabular Model for Feeds and Speeds of most CAM software just doesn’t fit real world CNC Feeds and Speeds needs, in other words.

Capturing Surface Speed, Feed Rate, or any of these other variables is jumping the gun because they can change considerably based on cutting conditions even if you keep the tool and material the same. The problem is that this tabular approach is way over simplified and incredibly limited for the real world.

The tables are divided by materials and tools, and they want you to enter default parameters for Surface Speed, Cutting Feed Rate, Spindle Speed, Feed per Revolution, or similar things. Tool Table in Fusion 360 with Feeds and Speeds information columns… They want to create tables like these from Fusion 360:

Most CAM has a very flawed approach to feeds and speeds. I want to start with what not to do–don’t just fill out CAM Software tables.

I’ll use Fusion 360 to illustrate the examples, but most CAM Software approaches Feeds and Speeds the same way, so can use the same workflow. I had a customer ask recently if I would walk him through the workflow needed to use G-Wizard Calculator alongside CAM software, especially Fusion 360 which is the package they use.
