【 摘 要 】

The paper discussed the problems of effective machining of workpieces in small batches on CNC machines with multi-pallet systems, combined into flexible manufacturing cells (FMC). In the paper was reviewed timeline of such manufacturing cells. It is shown that in order to increase the efficiency of the CNC machines with multi-pallet systems into each flexible manufacturing cell is necessary to pick up different workpieces to be machined, based on the duration of their machining cycles and installation in pallets. It allows providing machines downtime minimization. To calculate the machining cycles of workpieces in a flexible manufacturing cell, it is proposed to use the graph-analytical method, which gives an enlarged estimate, and the method of simulation of manufacturing processes, which allows obtaining a refined decision.
