  • Speeds and Feeds – Bantam Tools

    Speeds and feeds are the collection of settings that determine the way in which a milling tool moves through material. Typically machinists enter their speeds and feeds into CAM software (such as Fusion 360 or the Bantam Tools Milling Machine Software) and the CAM software combines the speeds and feeds with the geometry of the tool to

    Mar 27 2019 · Inverse-time feed is not as complied as it sounds. Inverse-time-feed rates simply dictate the amount of time a particular stroke will take to complete. To calculate the time for a stroke divide the inverse-time-feed rate into 60. For example an inverse-time-feed rate of F1000 dictates that the commanded motion of that line will take 0.06
