In the article for practical application within the framework of creating a matrix theory of accuracy of multi-tool machining for a range of multi-tool adjustments (tool setups) of previously developed models of machining error, the necessity of dependence of the coordinate components of cutting forces on technological factors is shown. (parameters of cutting conditions, strength properties of the material being machined, deformation properties of the technological system, etc.). For this purpose, the tasks of cutting force models are established, a systematics of machining schemes used on modern lathes is carried out, highlighting two schemes for the formation of a machined surface (trajectory and profile), and the principles for developing cutting force models are given. Thus, the development of an algorithmic unified complex of mathematical models of cutting forces is substantiated, taking into account the introduced systematics of machining schemes according to the mechanism of formation of the machined surface.

“…One of the most important factors in improving the productivity of the technological process is the concentration of transitions. The highest efficiency of concentration of transition is ensured by its implementation in multi-tool adjustments [1][2][3][4][5][6]. Dimensional accuracy is a paramount requirement in the design, debugging and implementation of the technological process.…”

Based on the developed models, the article reveals the degree of influence on the machining accuracy of a complex of technological factors, including the structure of a multi-tool single-carriage adjustment, the deformation properties of the subsystems of the technological system, cutting conditions. A number of ways to control multi-tool single-carriage machining based on the developed accuracy models are shown, including improvements in the structure of multi-tool single-carriage adjustment, calculations of limiting cutting conditions. The developed control models make it possible to predict the accuracy of machining for given conditions, including such technological components as the adjustment structure, properties of the technological system, machining conditions, thereby creating a methodological base for CAD for multi-tool single-carriage machining. They can serve as a basis for developing a digital twin model of the process.

The article provides a matrix generalization of distortion models and scattering fields of dimensions performed during turning with a spatial arrangement of the tool, taking into account the simultaneous action of all components of the cutting forces of the setting tool and elastic deformations of the technological system in all coordinate directions. A full-factor model of dimension distortion for single-carriage adjustment has been developed, which allows taking into account not only planeparallel movements of technological subsystems, but also their angular movements around base points. Thus, the Eq. developed for the total displacement vectors 𝑢𝑖 is proposed to be taken as the basis for a full-factor model of the machining error. The presented analytical models describe only plane-parallel displacements of contacting bodies. It is shown that in order to take into account the whole complex of displacements in them, i.e. and angular displacements, it is sufficient to replace the plane-parallel displacement vectors of each contacting body 𝑟𝑖.
