IDENTIFICATION OF DOMINANT FACTORS IN TECHNOLOGICAL PROCESSES OF MACHINING MACHINE PARTS

The article discusses issues related to identifying the dominant factors in the technological processes of mechanical processing of machine parts. It points out that not all processing factors have a clear impact on the quality parameters of parts during processing. Mathematical methods for identifying dominant factors from the total set of factors are noted. It is emphasised that, when there is insufficient information about the factors of technological processes and their significance, the most effective method for identifying the dominant factors from the general set is the expert assessment method. Using the example of mechanical processing of a shaft, the sequence and results of identifying the dominant factors of the technological process of its processing are given
