Abstract
The invention relates to a method for ascertaining a rough trajectory from a specified contour for controlling a machine tool which has at least two mutually redundant drive devices for carrying out superimposed movements, wherein the contour is determined by a contour function (P, p) which is defined in portions by contour nodal points P−Pand respective contour portion functions p−p, wherein a respective contour portion function pconnects two adjacent contour nodal points P, P, wherein the rough trajectory is determined by a rough trajectory function (Q, q) which is defined in portions by rough trajectory nodal points Q−Qand respective rough trajectory portion functions q−q, wherein a respective rough trajectory portion function q connects two adjacent rough trajectory nodal points Q, Q, wherein, for each contour nodal point P, a respective assigned rough trajectory nodal point Qis ascertained in such a manner that a difference in the gradients of the two adjacent rough trajectory portion functions q, qwhich contain this rough trajectory nodal point Qis minimal and that the distance of the contour nodal point Pfrom the rough trajectory nodal point Qsatisfies a specified distance condition.
