Performance and reliability of automated cutting machines is an important indicator of
efficiency of their operation
.
However, the scientific literature does not address the issues
of their work in terms of servicing a large number of requirements for processing of parts
and service intensity of these requirements, described by the method of queueing theory
.
The article considers
mechanisms of flow applications for processing, failure of equip-
ment, tools and service flows on the example of a machine tool as a kind of queuing sys-
tem
. The p
roposed method for describing the mechanism of application stream formation
and services allows to estimate effect of the conditions machine operation on its perfor-
mance and reliability
.
The study results extend the knowledge about the use of perfor-
mance and reliability theory, queuing theory in the analysis of the operation of cutting
machines and other processing devices of discrete
.
Keywords:
automated cutting machines, performance, reliability, flow applications, the
flow of services, the state probabilities of the machine, the queuing system
.
