The sustainable manufacturing and machining concept using functionally-oriented technologies involves design and technological, economic, social, and environmental dimensions. Currently, rational approaches in the environmental direction are primarily based on effectively recycling cutting tools and chips to minimize the consumption of cutting fluids and energy. However, developing functionally-oriented technologies using economic criteria improves product competitiveness, increases machining productivity, and ensures the choice of rational cutting modes while manufacturing machine parts. The optimization technique of cutting modes during parts machining according to economic criteria using Markov chains was suggested for the first time. The target function is the maximum machining time in specified technological operations or certain technological steps during part manufacturing. It is determined according to regulated reliability indicators, e.g., gamma-percentile operating times to failure as a primary parameter of dependability. Adopting the developed technique in mechanical engineering practice will allow the optimization of cutting modes of parts machining according to regulated reliability indicators due to the operational conditions.

Abstract
The sustainable manufacturing and machining concept using functionally-oriented technologies involves design and technological, economic, social, and environmental dimensions. Currently, rational approaches in the environmental direction are primarily based on effectively recycling cutting tools and chips to minimize the consumption of cutting fluids and energy. However, developing functionally-oriented technologies using economic criteria improves product competitiveness, increases machining productivity, and ensures the choice of rational cutting modes while manufacturing machine parts. The optimization technique of cutting modes during parts machining according to economic criteria using Markov chains was suggested for the first time. The target function is the maximum machining time in specified technological operations or certain technological steps during part manufacturing. It is determined according to regulated reliability indicators, e.g., gamma-percentile operating times to failure as a primary parameter of dependability. Adopting the developed technique in mechanical engineering practice will allow the optimization of cutting modes of parts machining according to regulated reliability indicators due to the operational conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
