Multi-cutter turning process stability analysis

Abstract: This work displays results of a modelling-based investigation a process of multi-cutter turning process focusing on the stability of nominal steady-state case. The modelling is based on the new surface formation equations, on the equations of motion and on a rational fraction cutting law. The influence of the parameters of the system on the stability of the steady cut is analyzed.

“…Problem formulation. At the same time, due to the development of various non-classical cutting schemes, in particular, using multiple cutters simultaneously, a number of new problems related to the analysis of the dynamics of the multi-cutter cutting process arise [20][21][22][23][24][25]. Note that multi-cutter turning allows combining different types of processing (roughing and finishing), the cutting depth (the thickness of the layer to be removed) in one pass can be increased, the transverse components of cutting forces can be balanced (which is important especially for turning long parts), manufacturing time is significantly shortened [26,27].…”

“…One of the methods of increasing the productivity of the turning process is the use of multiple cutter systems, in which the effective depth of cut in one pass can be increased, the cutting forces can be partially balanced (especially in the transversal direction, which is particularly important for thin-walled workpieces), cutting operations can be combined (e.g., raw and finishing), and the processing time can be substantially reduced. Several works have addressed multiple cutter turning systems in recent years [2,4,8,9,10,11,12,13,19,20].…”

“…Подробное теоретическое и экспериментальное исследование динамики вибрационного сверления с различными вариантами управления выполнено [23]. В данной работе развиты алгоритмы управления, изложенные в [3,4], представлен алгоритм адаптивного управления по размаху колебаний [5], эффективность которого доказана расчетно и экспериментально. В то же время дробление стружки зависит не только от амплитуды колебаний, но и от фазовых соотношений между колебаниями режущих кромок инструмента во время последовательных проходов по участку обрабатываемой поверхности.…”
