A copy sensor with circular interpolation for machining units, fitted with a membrane connected with a tracing finger transmission system, interacting with a master module, characterised in that a diaphragm (3) is placed in a slot of a position transducer (2) connected with an input of a linear amplifier (6) which included in a a feedback circuit is, fitted with a constraint signal shaping system (5) and with a potentiometer (7) and connected with an optical indication system (4), whereas the constraint signal shaping system (5) is connected with the systems (8) and (9) which shape the forward and backward signal and the advance signal, the first of which is connected with an amplifier (10) of the forward-backward line, and the other with the amplifier (11) of the advance line.<IMAGE>
