Abstract

Restorative processing of large-sized parts of rotating technological units, which include bandages and kiln rollers, is currently performed using embedded machine modules. At the same time, periodic processing is carried out during the operation of the unit without stopping. This processing requires special technical and technological approaches. This is due to the large dimensions of the parts and the inconstancy of the position of the axis of the rotating part, installed on two support rollers and having an error in shape in cross section. The technologies used are characterized by insufficient study of surface formation process during machining and arbitrarily set processing modes. An urgent task is to develop methods for finding rational modes in which the required accuracy and processing performance will be provided. A special place is occupied by the issues of processing modeling to find the optimal technological modes, taking into account the technical and physico-mechanical features of the process. The development of adequate mathematical models requires a deep analysis of the functional features of the equipment and technological features of the process. It is established that for optimization of processing modes it is necessary to enter a number of restrictions related to the tool, the driving feed, the rigidity of technological system, the quality of processing. In this case, the processing capacity is used as the target function; the depth and feed are used as varied parameters.
