Synthesis of the Technological Process for a Robotic Complex on the Basis of Knowledge

Abstract

A new approach to the synthesis of technological operations is based on the sequential combinations of the knowledge action, which are implemented by the robotic complex. Synthesis of the executive actions on processing and assembly of a product it is the sequence methods processing for achievement of the required attributes determined by the drawing of a product. The flexibility of the process for preparation of a robotic complex is achieved by selection of the best solutions, which meet the requirements of the current production situation. A new method of knowledge representation is based on XML schema for creation of the knowledge elements for the technological objects and actions. Creation of a knowledge base allows us to save the tested variants of the technological processes after their modeling in CAD/CAM systems and to improve their performance. Formation of i - operation by chaining the executive actions, is composed of the elements of knowledge of EKi, EKk, EKn, EKm, and is based on the data of the 3D model of the product and its attributes. The option of formation of the next operation is determined by the state of the current production situation. Condition of synthesis of the executive actions it is carried out due to influence of attributes of the drawing of a product and visualization 3D - models, also due to the following attributes: the maximal amount of the allowance; grade of the processed material; grade of the tool material; accuracy class of a machine; and necessity to use a number of simultaneously controllable axes of movement of a tool. Serial combinations of the working and auxiliary passages will make possible a synthesis of the control of the program of work of the robot technology complexes (RTG). The pro-posed approach to the structural synthesis of the technological process can significantly reduce the preparation time, generation and adjustment of the control programs for RTC.
