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.

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.

Two generalized cutting schemes predetermining the machining error formation mechanism are distinguished: contour machining, when the profile of the machined surface is formed by the corresponding tool path - contour machining; profile machining, when the profile of the machined surface is formed by the corresponding tool profile - shaped tool machining. For the trajectory scheme, the known force relations are generalized to a spatial curvilinear trajectory. Generalized dependencies for the cutting force components of form, slotted, cut-off and groove cutters are derived for the profile scheme. The evaluation of the adequacy of the proposed model for cutting force components is carried out on the basis of a specially conducted experimental research of the profile turning process with direct measurement of forces at different levels of varying technological factors. Thus, the developed dependences of the coordinate components of cutting forces on technological factors (parameters of cutting conditions, strength properties of the processed material, deformation properties of the technological system, etc.) allow using them for the practical application of machining error models in the matrix theory of multitool machining accuracy.
