    Example: Calculate the speed and feed for a ¼″ HSS drill bit in soft cast iron on a manual milling machine in the lab. First, lookup the recommended surface speed (peripheral velocity) in Table 1: V ≈ 100 ft/min. Next, calculate the spindle speed from Equation 2: N [rpm] = 12 × V / (π × D). = 12 in/ft × 100 ft/min / (π × 0.25

  • The Milling Machine 8: Quill Feed Virtual Machine Shop

    The automatic quill feed is a nice feature to have for certain drilling, boring, and reaming operations. The quill feed mechanism is driven by the spindle so the speed of the quill feed varies with the speed of the spindle. However the rate of feed is fixed as a distance moved per revolution. This is very much similar to the feed
