Abstract
On the example of the process of machining the statin of an electric motor, the possibility of determining the error from elastic deformations of a technological system by the finite element method is shown. To check the adequacy of the model, a comparative analysis of the calculation results with experimental data was carried out. The results showed that the amount of deviation from roundness obtained as a result of the simulation turned out to be 16% less (0.134 mm) than actually obtained during processing (0.16 mm). Simulation data confirm that the error from elastic deformations of the technological system has a maximum value. The remaining components of the error account for about 16% of the deviation.
