Accelerated approach to assessing the machine operation and its technical potential

The paper proposes a universal approach to assessing operation and technical potential of the machine tools in all groups and types. It analyzes the main consumer properties of a machine. The paper shows that using all the machine quality indicators could lead to uncertainty in assessing its operation potential. Analysis results demonstrate that technological accuracy is selected as the main assessment parameter. Based on representing machine as a multi-loop closed system, a block diagram of the factors’ activation is created forming the machining error. The factors considered make it possible to compile equations for computing the machining error and probability of the machine failure-free operation according to the technological accuracy. This approach was tested on the wheel-turning lathes of various designs. The obtained results were compared with the production statistics.
