Method for controlling relative displacements of a tool against a workpiece

Abstract

The invention relates to a method for controlling the relative displacements of a tool against (4) a workpiece (2). According to said method, a tool axis (43) of the tool (4) can be pivoted or shifted against the workpiece through all spatial dimensions for the machining of the workpiece (2) and the desired target contour (21) of the workpiece (2) is produced by a sequence of relative displacements of the tool (4) along a tool trajectory (6). The method is characterised in that the tool trajectory (6) is divided into a plurality of trajectory segments (61), the tool engaging with the workpiece (2) along said segments, whereby the orientation of the tool axis (43) remains constant within a trajectory segment (61), but can be varied over the entire tool trajectory (6) and that each end point (63) of a trajectory segment (61) is linked to a starting point (64) of another trajectory segment (61) by means of a linking pivoting displacement (62), during which the tool is disengaged from the workpiece (2) and during the course of which the orientation of the tool axis (43) can be modified.
