ALGORITHM FOR GROUPING PARTS CONSIDERING EQUIPMENT UTILIZATION

Abstract

The article presents studies of the influence of factors of forming groups of parts on the efficiency of the implementation of the group technological process, the development of an algorithm of grouping by part operations adapted to modern production conditions, taking into account the workload of machines. Taking into account the factors of the developed algorithm, a structural and technological analysis was carried out for a given group of parts, taking into account the production batch. Among the considered possible options for processing the surfaces of workpieces, more rational ones were selected based on the uniformity of the loading of technological equipment. An alternative version of the group technological process was developed by redistributing detail operations, taking into account the factor of loading of CNC lathes and milling machines. As a result, the downtime of the CNC machines involved was significantly reduced, the total time for machining workpieces was reduced by 40%, the operating time of the CNC lathe was reduced by 30% compared to the initial machining option. The patterns of influence of technological factors on the process of forming groups of parts when designing a group technological process were established; an algorithm for grouping parts was developed, which allows to increase the efficiency of the use of production resources; the effectiveness of the proposed algorithm was confirmed based on the calculation and analysis of technical and economic indicators. The use of a parts grouping algorithm taking into account the workload of machine tools in serial production using modern machinebuilding technologies is proposed.
