Abstract
Milling machine apparatus and method for controlling the relative movement between a working surface and a cutting edge in which said relative movement approximates a mathematically definable path and occurs in a series of line segments each intersecting said path at first and second points with the second point of each line segment being the first point of the next successive line segment. The system comprises first means for determining a maximum distance d' between each successive line segment and said path measured along a line extending from a predetermined reference and passing between said first and second points, where d'=d+.DELTA.d, a predetermined range of value. Also provided are second means responsive to the determination of d' for each successive line segment to then establish the first point of intersection of the next successive line segment, and control means responsive to the determined points of intersection to generate prime moving control signals. Prime moving means respond to said control signals to cause the cutting edge to cut along the successive line segments with respect to said working surface.
