Production machines maintenance based on digitalization

Abstract

Introduction.Digital data and analytics transform the role of the production equipment maintenance. Analytical information of sensors placed on the product allows continuous monitoring of the production machines operation and their timely servicing. Thus, defects in technical equipment are identified, the analysis of which enables to develop algorithms for monitoring and forecasting, and to prevent equipment from overshooting the limits of the safe operation.Materials and Methods.Basic digitalization principles and the digital images structure are presented. A mathematical method is used to describe the digital image vector and the control system algorithm.Research Results.The achievements of the known systems of maintenance and digitalization of various machines are summarized. The application of a dynamic digital image made it possible to determine the desired levels of the production facilities maintenance. An optional version of monitoring the equipment state within the framework of the production digitalization concept is shown. It is based on the proposed algorithm for an autonomous control of the process state.Discussion and Conclusions.The construction of machine digital images in accordance with the main stages of its life cycle is described. The task of automated maintenance of machine tools based on digitalization is considered.

Economic Issues On Equipment Capacity In The Projects Of Production Digitalization

“…The authors of the publication "Production machines maintenance based on digitalization" (Tugengold et al, 2019) proposed the construction of digital images of the machine in accordance with the basic stages of its life cycle, and the study "Prognostic approach to equipment maintenance as a leading element of digitalization of production processes" (Reznikova & Rashoyan, 2019) 1576 approach, which widely uses statistical control of production processes and allows forecasting trends in the state of equipment. Application of such approach will allow to reduce the percentage of defects, to carry out preventive maintenance of equipment in time, which, in turn, will reduce the probability of unforeseen costs due to the onset of failure of technological equipment.…”

System management technology for technical maintenance of transport and technological machines

“…In relation to the subsystem С1 the task is more complicated, but it is currently quite successfully solved by using, first of all, various types of redundancy (reservation of resourcelimiting blocks) and special compensation devices [10].…”

The use of information technology in the design of chippers for the production of technological chips

“… search for information about similar equipment at the stage of marketing analysis [3];  machine design design using specialized CAD systems such as Autodesk Revit and Autodesk 3DS Max [4];  calculation of the created models, for example, using the finite element analysis method [5];  automation of the design process and calculation of the machine dynamics [6];  conducting virtual tests of machines to achieve high performance indicators [7];  development of technical processes and control programs for the manufacture of parts on CNC machines [8];  monitoring the state of the machine during its operation [9];  management of maintenance and repair of the machine [10,11,12]. Today, both Russian and foreign manufacturers offer a wide range of chippers for processing round and split timber, low-quality wood, sawmill and woodworking waste, logging waste and wood scrap into chips.…”
