Abstract
The method for simulating bending of a tube by means of at least one bending machine comprises a step of calculating at least one cycle of bending commands (30, 35) related to at least one tube-manufacturing parameter as a function of a set of tube data (10) and of a set of technological data (20). There is obtained at least one three-dimensional geometric model (40) of at least one bending machine and associated mechanical tools as a function of at least one parameter (50) derived from the cycle of bending commands calculated in this way (30, 35). In accordance with the cycle of bending commands calculated in this way (35), obtaining a three-dimensional and kinematic simulation of the process in which the tube represented in this way by the set of tube data (10) is bent by means of at least one bending machine and associated mechanical tools represented in this way by the corresponding three-dimensional geometric model (40). There is verified the possibility of manufacturing the tube by means of a bending machine and associated mechanical tools during the three-dimensional and kinematic simulation obtained in this way.
