Contributions to optimization of part program in processing and mesurement phases of wheelset running profile
Journal Title: Proceedings in Manufacturing Systems - Year 2015, Vol 10, Issue 4
Abstract
The paper presents the running profile features of the railway wheels, profile representation and optimization possibilities in order to elaborate the part program for processing the wheelsets by turning. The segments of the profile, which require the analysis of the approximation error with line segments and arcs, were highlighted. For this purpose, the research focused on achieving a small number of phrases in the part NC program. The established methodology was applied to one of the standardized profiles. In the paper values of applying this optimization methodology for a curved zone of the profile are presented. The resulting data can be also useful for the system of measuring and control of the profile after processing on the machine tool. Thus, it is easily possible to determine the concordance between the resulted deviations and the allowable ones required by the standards. It is also presented a measurement system that can be integrated in the machine-tool, resulting in a closed-loop measurement and processing system.
