Feeds speeds

The whole feeds speeds topic is arguably the most daunting part of learning CNC Feeds is feedrate on some CNCs with a fixed tool and moving plate this is the speed at which the material is fed into the cutter on a Shapeoko this is the speed of the gantry pushing the cutter into the material Speeds is the rotation speed of the endmill i.e RPM value.
