NC parameterization in rail wheel set re-profiling machining
Journal Title: Proceedings in Manufacturing Systems - Year 2017, Vol 12, Issue 1
Abstract
The paper deals with Computer Aided Maufacturing (CAM) in the processing by turning on a lathe machine tool type, which is subject to a process of remanufacturing. The feed drives of the lathe are redesigned being associated with numerical control equipment. Moreover, on the machine tool is adapted a specific measurement system. The paper presents the most common defects and necessity of reshaping the wheel, which have suffered a process of wear, by turning on specialized machines. The paper presents a methodology and a case study for parameterization of a NC program for automation of a re-profiling turning process for a rail wheel set. The NC parameters are defined based on the nominal profile and the real damaged profile. The algorithm calculates the machining offset, depth of cut and number of passes based on the coordinates of the measured points.
