### Feeds Amp Speeds Shapeoko Cnc A To Z

The whole feeds amp 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.The whole feeds amp speeds topic is arguably the most daunting part of learning CNC.
