Speeds and feeds for cutting plastic
WebDec 7, 2024 · It measures the linear distance moved by the cutting tool against the machined part at a given time. Cutting speed is measured in millimeters per minute … WebMar 19, 2024 · The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter. On the milling machines we have here at LBCC, the feed is independent of the spindle speed. This is a good arrangement and it permits faster feeds for larger, slowly rotating cutters.
