Sažetak
The paper focuses on the problem of control of accuracy of forming elastic-deformable shafts with low rigidity. In particular, results of analysis of basic factors affecting the accuracy of machining of low-rigidity shafts such as the stiffness of the technological system, geometry of cutting tool, lathe temperature, degree of cutting tool wear, cutting tool strength, lubrication-cooling fluid and machining parameters are presented. Moreover, the performed analysis encompassed the effect of stiffness of particular elements of the technological system, the analytical relations determining the changes of defined parameters, values of elasticity of the fixed headstock and tailstock, as well as of the stiffness of the machining system from the zones of rigidity of the parts. To analyse appearing errors in the real industrial conditions, the study was realized on the example of manufacturing precision mechanics tooling in two and a single pass, with the application of specific parameters of machining.
