Method for adjusting a workpiece-supporting assembly of a machining centre for workpiece machining

摘要

The method involves adjusting deformation model describing physical conditions of a workpiece-supporting assembly (2) of a machining center (1) based on deformation measurements. The model is implemented as non-variable computing model in a machine controller (11). Position correction values for the controller are calculated with the computing model. Position correction is automatically executed at the assembly by using the correction values such that elastic deformation of the assembly is determined and adjusted in spatial direction by using the controller.
