Abstract
The invention relates to a programming method for the reprofiling of rails according to which the track is divided in successive sections as from a starting point and for each of these sections one proceeds for each line of rails to the measuring of the wavelength and/or of the amplitudes of the longitudinal undulations of the rolling table of the rail and to the measure of the transverse profile of the head of the rail. One compares thereafter a reference profile to the measured transverse profile and determines the transverse metal section to be removed to correct the transverse profile of the rail, then one determines as a function of the amplitudes of the longitudinal undulations of the rail the longitudinal metal section to be removed to correct the longitudinal profile of the rail. One determines the total section of metal to be removed and as a function of the speed of working, of the characteristic of metal removal of each tool, and of this total metal section to be removed the necessary number of minimal tool-passes. The invention also relates to a machine for reprofiling the rails according to the method.
