“…The geometrical accuracy one of the main indicators for characterizing both the processing and the equipments and tools used. The basis of this work is the variation method for metalcutting machines accuracy calculation [1,2] which is using uniform coordinates and gained development in the next works [3][4][5]. At processing accuracy researches on metal-cutting machines the main attention is paid to the accuracy of the machine tools though the structure of the metal-cutting system (MCS) always includes the cutting tool.…”

The bases of a variation method to calculate the metal-cutting systems accuracy for the first time are systemically stated in this paper. The main attention is paid to a problem of joint influence of geometrical accuracy of machine tools and cutting tools parameters on the details processed surfaces accuracy. The general mathematical model of metalcutting systems accuracy is presented in this work. The general model is the basis to develop the full mathematical model of turning metal-cutting system accuracy. The results of accuracy modeling at turning with a wide cutter are received when studying nature of influence of the lathe and the cutting tool geometrical errors on processing accuracy of cylindrical and face surfaces. The directions of further researches in the field of calculations of metal-cutting systems accuracy at difficult surfaces processing by the shaped cutting tool and also when accounting rigidity of the systems elements and the proceeding processes are revealed in the presented work. * Corresponding author: olesya-anikeeva@yandex.ru MATEC Web of Conferences 224, 01038 (2018)

The actual problem of modeling the influence of geometric errors of vertical milling machines on the accuracy of machined surfaces is considered in the paper. For the first time, a mathematical model of the accuracy of vertical milling machines is presented when processing a complex of keyway surfaces. The model was developed on the basis of a variational method for calculating the accuracy of metal-cutting systems, which is a development of the well-known variational method for calculating the accuracy of machine tools. The results of modeling the influence of geometrical errors of vertical milling machines on the accuracy of the machined surfaces of the keyway are given. Directions for further research of milling accuracy modeling with variable values of machine tool geometries are proposed. The work is useful for researchers engaged in research of the accuracy of technological equipment.

The paper is devoted to the topical issue of the formation of a variation method for calculating the accuracy of metal cutting systems. The current state of the basic variation method for calculating the geometric accuracy of metal cutting machines is determined. A transition from considering the geometric accuracy of only the metal cutting machine to considering the accuracy of the metal cutting system is made, which includes the metal cutting tool. The proposed directions for the development of the method are recommended to be divided into groups according to the criterion of linearized and non-linear formulation when building accuracy balances. The solution of the problem posed in the paper serves as a methodological basis for work on normalization and compensation of geometrical errors of machine tools, including the creation of the foundations of standards for the accuracy of metal-cutting machines and tools. This work is useful for scientists engaged in the study of the geometric accuracy of processing on metal-cutting machines, as well as the normalization and compensation of the geometric errors of machines.
