  • Method of generating a tool path
    Patent number: 9498847
    Abstract: Method for determining an adaptive tool path: provides an aerofoil with deposition plane; determines deposition plane points corresponding to leading and trailing edges and circle center constrained by suction and pressure surfaces at their greatest distance apart; determines circle center point edge position passing through deposition plane points; determines trailing and leading edge reference lines extending from the circle center point through trailing and leading edge points, respectively and mid-reference line(s) extending from the circle center point through mid-reference point(s) between leading and trailing edge points; trims and determines each mid reference line to the bounds of the suction and pressure surfaces; applies an adaptive factor to each mid reference line providing an adaptive point for each mid-reference line; determines an spline extending through the leading and trailing edge points and each adaptive point; and traverses a tool along the spline or offset path from the spline by a fact
    Type: Grant
