Abstract: Thermal drifts compensation method in a gaging device (1) with a transducer; the compensation method includes the steps of : determining and storing, in the course of a calibration operation, values of a thermal compensation coefficient (K) upon variation of a temperature (T) of the gaging device (1); detecting, in the course of a gaging operation, a current reading (X) of the gaging device (1); detecting, in the course of the gaging operation, a current temperature (T) of the gaging device (1); determining, in the course of the gaging operation, the current value of the thermal compensation coefficient (K) by means of the values of the thermal compensation coefficient (K) previously determined and stored in the course of the calibration operation as a function of both the current temperature (T) of the gaging device (1) and the current reading (X) of the gaging device (1); and correcting, in the course of the gaging operation, the current reading (X) of the gaging device (1) by means of the current value of the thermal compensation coefficient (K).

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.
