Determination of the error from elastic deformations of the technological system by the finite element method
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.
