<p>PURPOSE: To perform recutting work simply, with good accuracy, quickly and automatically by programming to determine a recutting category or the like according to knowledge on the rail such as reference contour, characteristic abrasion form or the like. CONSTITUTION: Rails are divided into a fixed number or parts, and concerning the rails of the respective parts, selection of reference contour, determination of characteristic abrasion form, selection of recutting machine form, selection of working speed, selection of machine tool constitution including power, and measurement of longitudinal waviness length and/or amplitude and lateral contour of the rail head are performed. A surplus amount of metal to be removed is determined, and a recutting category to be used is determined. programming is performed as in the following, According to the recutting category, a specified standard tool constitution to be used is determined, and a number of passes to be performed is determined to perform recutting work.</p> |
