Let’s say G-Wizard is recommending 400 SFM for your Surface Speed, and you think that’s too fast. The padlock only appears when the parameter has been overridden by the user. Many of the parameters sometimes have a little padlock next to them, for example there is one next to the Surface Speed parameter. If you’re going to cut with warnings or red lights, you want to be sure you know exactly what’s going on and that it’ll be okay. In general, go ahead and enter all the values for your cut before worrying too much about the traffic lights and warnings, but make sure to come to grips with them before actually using the Feeds and Speeds. Red on a traffic light means you’ve hit a limit of your machine. This is where G-WIzard will give you warnings by changing the traffic light colors or adding tips. I want to come back to this in more detail, but more now, notice the big green traffic lights scattered around. G-Wizard’s Feeds and Speeds Calculator… Traffic Lights & Tips With Warnings Just start filling in the form from left to right, top to bottom and your answer comes out at the bottom: To use the Feed and Speed calculator is simple. More quick videos are available from the G-Wizard Calculator Video University.Īs you can see from the video above, the Cheat Sheet can really help you figure out what you need to change to get a desired result. In the spirit that a picture is worth 1000 words, here is an in-depth demonstration of the G-Wizard Feed and Speed Calculator:Įverything you need to get started with the G-Wizard Feeds and Speeds Calculator. It’s a 10 minute video that covers things like chip thinning, relationship of cutter edge radius to chip thickness for best tool life, ballnose cutter compensation,and a number of other topics associated with feed and speed calculation. If you’re wondering why you’d care about all that, here is a quick course in Feeds and Speeds that fills in the blanks: ![]() Considerations such as radial chip thinning, and when it’s better to climb versus conventional milling are very important to getting the best results. The Feeds and Speeds calculator considers many additional variables that simple lookup tables and the SFM and chip load math every machinist knows by heart don’t. Getting the best feed and speed for your particular tooling and cutting situation is one of the most important steps to ensure maximum material removal rates, best surface finishes, and better tool life. ![]() ![]() G-Wizard’s feed and speed calculator is designed to help you determine the best feeds and speeds for particular machining operations.
