Control of processing at multi-tool two-support setup

Abstract

The accuracy of two-tool machining on automatic lathes is analyzed. Full-factor models of distortions and scattering fields of the performed dimensions, taking into account the flexibility of the technological system on six degrees of freedom, i. e. angular displacements in the technological system, were used in the research. Possibilities of design and control of two-tool adjustment are considered. Keywords turning processing, cutting mode, two-tool setup, full-factor model, accuracy, angular displacement, control, calculation Nizami_Yusubov@mail.ru

Theoretical Basis for the Development of an Algorithmic Unified Complex of Mathematical Models of Cutting Forces

“…As part of the creation of a matrix theory of the accuracy of multi-tool machining [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], for a range of multi-tool adjustments, two classes of error models for the dimensions performed have been developed:…”

“…Thus, for the practical application of the machining error models developed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], the dependences of the coordinate components of the cutting forces on technological factors are necessary (parameters of cutting conditions, strength properties of the material being machined, deformation properties of the technological system, etc.). These dependencies establish the so-called cutting force models.…”

“…Koshin's plane-parallel accuracy theory [18] of multi-tool machining is based on traditional empirical power dependences for the components of cutting forces. Machining error models in the proposed matrix theory of accuracy [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] are also formed using power dependences for the components of cutting forces:…”
