Abstract
The position of the inner surface of a hollow metal workpiece on a machine tool is detected by connecting an operating member of the machine, preferably a tool, to a first terminal of an electric power source; connecting the inner surface to a second terminal of the power source; moving the operating member gradually towards the inner surface to detect the emission of a signal generated by an emitting device interposed between one of the terminals and the inner surface, and corresponding to a condition in which initial contact is established between the operating member and the inner surface; and determining the position of the operating member at the instant the signal is emitted.
