Automation of Calculating the Amount of Technological Equipment and Load Factors in Mechanical Assembly Production

Abstract

The paper addresses the problem of improving the efficiency of designing mechanical assembly sections through the formalization and automation of determining the required amount of main technological equipment under non-flow production conditions. The relevance of the study is determined by the need to reduce the labor intensity of design calculations, increase their accuracy, and ensure the validity of equipment selection when designing production units of machine-building enterprises.

An algorithm for calculating the number of machine tools is proposed, based on determining the machine-time capacity of machining operations, taking into account the annual production program, the structure of the technological route, and the effective annual operating time of equipment. The algorithm provides determination of both the calculated and accepted number of machines, as well as equipment load factors and utilization factors based on main processing time, which serve as generalized indicators of the efficiency of the technological system.

A block diagram of the algorithm and a software tool implemented in the Delphi environment have been developed. The software automates calculations, reduces the probability of errors associated with manual data processing, and enables analysis of the equipment load structure. The results are generated in numerical form with the possibility of further graphical analysis, which makes it possible to identify load imbalance between operations and determine reserves for improving the efficiency of the technological process.

The scientific novelty lies in the formalization of the procedure for determining the equipment composition of mechanical assembly sections with an integrated analytical assessment of its utilization efficiency based on a system of coefficients. The practical significance of the results lies in the possibility of applying the developed software tool in the design of production units of machine-building enterprises as well as in the educational process for training specialists in mechanical engineering.
