Sterowanie adaptacyjne procesem frezowania HPC

W artykule przedstawiono podział oraz ogólną charakterystykę najczęściej stosowanych w obrabiarkach CNC systemów sterowania adaptacyjnego. Na podstawie przeprowadzonych badań doświadczalnych procesu wysokowydajnego frezowania stopów aluminium określono stopień skrócenia czasu obróbki spowodowany zastosowaniem wybranego układu sterowania adaptacyjnego.

This paper presents an overview of the division of the most widely used adaptive control systems. Figure 1 shows an example of adaptive control off-line, and in Section 2 of the paper there is described the on-line adaptive control system as an example of Marpos ARTIS. In Section 3 the high-performance milling (HPC) of aluminum alloys is discussed. In the machining center HSC 55 Linear with implemented module ARTIS there were performed experimental investigations of the machining process with and without adaptive control. The experimental setup is shown in Figure 4. The experiment was carried out for two nominal values of feed per minute ft=1m/min and 2m/min. Other machining parameters were as follows: depth of cut ap=5 mm, spindle speed n=9000 r/min and cutting speed vc=350 m/min. The milling process was realized by using a carbide end mill. The results are shown in Figures 5 and 6. Based on the obtained results it was found that the milling process has a significant impact on shortening the manufacturing process. The use of adaptive control allowed for reduction of the processing time by 15 - 24%.
