Abstract
A numerically controlled machine tool for machining a workpiece is provided. The machine tool includes a work spindle, at least one feed axis, and a device for collision monitoring on said machine tool, wherein the device for collision monitoring includes a collision sensor mounted on a machine part of the machine tool, collision detection means for detecting a collision of machine parts of the machine tool when a measuring value detected by the collision sensor exceeds a collision limit value, and signal output means for outputting a stop signal for stopping the at least one work spindle and the at least one feed axis, of the machine tool when the collision detection means detects a collision. The machine tool includes a unit for determining the collision limit value on the machine tool.
