Control method for a machine tool with numerical control

摘要

A control method for a tool machine is provided. The machine tool includes adjustment devices which are used to produce relative displacement between a machining head and a work piece. The adjustment movements are detected by sensors associated with the adjustment devices. A value for the relative displacement from the machining head to the work piece is determined from the signals of the sensors associated with the adjustment devices. The adjustment devices are controlled according to the value of relative displacement in order to produce predetermined adjustment movements. State variables which describe relative displacement between the machining head and work pieces are detected in at least one additional sensor. The state variables are taken into account when the value for the relative displacement is determined.
