![]() ![]() Granted, it does all kinds of super powerful and useful things no other calculator will do, but it still looks very familiar if you ever use a Feeds & Speeds Calculator. The Feeds/Speeds tab in G-Wizard is a very traditional Feeds & Speeds Calculator. You just seen how easy it is to get really good Feeds & Speeds into Fusion 360, or most any other CAM package. Set Entry to “Plunge” and use the ipm value. Set Entry to “Ramp” and use the ipm value. GW makes no recommendation for this and assumes you’ll use same value as “Cutting Feedrate” Now, here’s the mapping showing which G-Wizard field to use for each Fusion 360 field. I’d also use this feedrate for Lead-In and Lead-out. Just use the lower feedrate for the ramp. There’s no reason to use a different Ramp Spindle Speed, though Fusion 360 lets you specify one. See the little message when the mouse cursor hovers over RPM? Just click that title and it copies the spindle speed onto the clipboard so you can take it and paste into Fusion 360.Ĭheck the little menu on the right that says, “Ramp”. This goes very quickly, because G-Wizard helps you with the task: That gets you a whole bunch of the information Fusion 360 needs, which you can proceed to copy over into F360. You need to copy your Feed and Speeds from G-Wizard to Fusion 360… Cut & Paste into Fusion 360 Now you’ve got a result that’s ready to go, such as this: Give it a tool stickout that will allow enough clearance in the cut but no more to minimize deflection. ![]() Then, based on how you set up your Toolpath in Fusion 360, give G-Wizard the same Cut Width and Cut Depth. Select the same Machine, Material, and Tool in G-Wizard. In fact, most of our users just leave G-Wizard open whenever they start up their CAM software so it is handy when they need it. Bring up G-Wizard Calculator (or whatever you’re using for your Feeds & Speeds) and use it to figure out what these values should be. ![]() Ignore them, they’re not very good as we discussed. Now this box is going to come up with the defaults from the Tool Library. Here’s an adaptive clearing toolpath I created for an old project when I was finishing some AR-15 lower receivers:Īdaptive Clearing Toolpath for an AR-15 Lower Receiver…Īnd here’s a closeup of the Feeds and Speeds parameters: 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.
