POSITION-DEPENDENT COMPLIANCE COMPENSATION IN A MACHINE TOOL

摘要

The invention relates to a method and a device for position-dependent compliance compensation in a machine tool. To permit the lowest possible machining time or greatest possible contour fidelity in the machining of a workpiece with a machine tool, the following method steps are proposed:—deriving the compliance (2) of the machine tool (1) at a position of a tool of the machine tool (1) from machine data (3) stored in a memory,—determining a machining force (4) acting on the tool during a machining process at said position,—modification of at least one machining parameter (5) that has an influence on the machining process for the said position in dependence on the derived compliance (2) and the machining force (4) in such a way that a displacement (6) of the tool with respect to a desired position that is caused by the compliance (2) of the machine tool (1); and the machining force (4) is counteracted.
