Abstract
A data set (D) is provided for machine control of a grinding machine to determine time-efficient, collision-free travel paths. The data set has a collision parameter of “0” or “1” in each separate coordination point (X, Y, Z, A) as well as for each combination of the separated tool types (WZI) and workpiece types (WSJ). The collision parameter indicates if the constellation assigned to the corresponding coordination point (X, Y, Z, A), which means the relative position of workpiece (11) and tool (3), does or does not result in a collision or spatial overlapping of the tool and the workpiece. The data base (D) forms a lookup table that can be used to check given paths or expansions or the step-by-step layout of paths. The computation of time-efficient paths can be performed within a few seconds, even at limited computing capacities.
