FEATURES OF MODELING THE BEHAVIOUR OF TECHNICAL CUTTING SYSTEM AT DRILLING
The article describes the details of modeling the behavior of the technical system in relation to drilling. Functional diagram of drilling is proposed and decomposing of drilling operation is held. In this case, the system is divided into subsystems that have their vectors of input and output variables as well as the state parameters of the subsystem. In addition, each subsystem is interconnected both directly and by feedback. The dependence of the state of output variables from input variables and parameters of the technical system are proposed. The impact of changes of the state of technological system parameters on the output variables of drilling operation is shown. However, these parameters affect the numerical values of the output variables of the technological system.
