Abstract

Industrial robots are used for machining in mechanical engineering. This trend is associated with an increase in the geomet-ric complexity of parts and wider kinematic capabilities of industrial robots in comparison with classical CNC machines. The article analyzes the technological capabilities of using industrial robots in finishing machining operations, and pro-vides the reasons for limited robots introduction Schemes of construction of technological operations are given: "part in hand" and "tool in hand". The factors influencing the choice of the preferred machining are studied. The areas of effective application of passive and active adaptation tools are given. The article provides two main reasons for possible vibrations under robotic manipulation: e.g. low rigidity of the industrial robot structure and shape errors effect in the previous opera-tion. The problem of developing a sustainable code conversion for the amount of material removal is discussed. The problem statement is due to the fact that the model of the cutting process varies greatly depending on the cutting conditions. Force control work makes it possible to take into account the rigidity of the robot without sacrificing the running accuracy in six coordinates. The article discusses the use of a neural network and a genetic algorithm in the development of a robotic pol-ishing operation for a flat surface within limited access constraints. The authors of the article have developed a postproces-sor for controlling an industrial robot in case of variable tool overhang and uneven tolerance. Special technological equipment has been designed and manufactured for this purpose. Experiments on testing of the developed algorithmic and software have been conducted in the laboratory "Industrial Robots and Automation Tools"
