Cutting speed, feed rate and the depth of the cut are called cutting conditions when you group all three together. Your cutting conditions are determined by machinability rating comparing materials on how well you can machine them. A milling machine must be set up so that its cutter will operate at the right cutting speed. To find out what.

2020-5-26The 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.
