Patent Abstract

The invention relates to a monitoring method for a numerically controlled machine tool, in particular a mill-turn machine (1) with at least one rotatory workpiece drive and a separating protective device (6), wherein according to the invention an actual geometry of a workpiece (2) and/or an actual mass distribution of the workpiece (2) is determined and compared with a predetermined reference value of a permissible geometry and/or a permissible mass distribution. According to the invention, the monitoring device has at least one means for measuring the mass of a workpiece (2) clamped on a workpiece table (4) and/or at least one sensor (5) for detecting the workpiece geometry.
