“…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.

In the work, the design of the tool – boring bar for parallel machining of conical surfaces and threads in coupling-type parts with opposite directions, same inclination, coaxial conical surfaces and threads is given, and their generalized design features are presented for the machining of couplings of different types and sizes. With the application of the designed tool - boring bar to machining of inner surfaces of couplings, their machining accuracy, especially accuracy of coaxiality of threads, thus the load-carrying capacity of the couplings increases, the technological cost of their production is reduced, and the efficiency of their use is ensured.

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.
