ABSTRACT:
A method and a relevant apparatus for controlling the machining of a piece (18,38) rotating in a numerical control machine tool (33) includes the steps of detecting instantaneous values (V(i)) indicative of the dimensions of the piece during the machining, performing dynamic processing of the detected instantaneous values and controlling at least one machining phase on the basis of the processing. The method includes dynamic calculation of average values (M(j)) of sequences of the detected values, acquisition of a variation index (P) indicative of the average values trend during the machining and of a correction coefficient (K) that allows for the delay of the calculated average values with respect to the actual dimensions of the piece, and processing of an instantaneous dimension (RI) of the piece that is transmitted to the numerical control of the machine tool for controlling the machining.
