* Look-ahead does just what its name implies; it looks ahead of the data it needs to mill at any given moment to verify that the CNC will be able to handle the demands the path will put on the machine. If the data check reveals that there may be a problem, feed rates for intermediate points along the contour are added, adjusting the feed rate downward to the maximum feed rate that will still yield an accurate surface.
