the comparative analysis theoretical and experimental data

With application of the added machine tool for processing of pins the supervisory control of accuracy and research of quality of the processed surface have allowed to execute carrying out of experimental researches.

The received results are shown in tables 4.3 - 4.4.

The cut areas

Coarsenesses

On the received data in co-ordinate axes schedules of comparison of settlement and valid values of the area of a cut and a surface roughness (drawings 4.13 - 4.14) are constructed. For more convenient and evident data presentation, we will arrange values on increase.

Apparently from the received data (table 4.3 - 4.4, drawings 4.13 - 4.14) the processed surface of a pin has the set accuracy and quality of a surface.

Drawing 4.13 - Comparison of results of experiment and calculations of parametre of the area of a cut

Drawing 4.14 - Comparison of results of experiment and calculations of parametre of a coarseness

The divergence between settlement and valid sizes of parametres of the area of a cut and a surface roughness does not exceed 9 %. Thus the greatest divergence is noted on boundary areas of an experimental research. The average divergence does not exceed 5 %.

Divergence presence is characterised by presence vibroustojchivosti a model and real system, considering which influence will complicate process and modelling research.

The given technique is applicable for repair processing of pins of mills under operating conditions, thus empirical dependence has estimated character by optimisation of technological parametres of rotational processing of working cylindrical surfaces of pins of mills. Thus it is necessary to consider, that the equation gives the underestimated results.
