Abstract
The invention relates to a method for producing a thread in a bore (2) by remote automatic machining characterized in that the method consists in introducing into the bore (2) an electrode (11) provided with a thread (20) whose shape and dimensions are pre-determined according to the shape and dimensions of an inside thread to be produced, in machining the internal threads by electroerosion displacing the electrode (11) in an orbital manner in the bore (2) according to a predetermined number of operations and in adjusting the machining parameters according to each operation. A device for carrying out said method is also disclosed.
