With these diploma thesis was created conceptual project of manufacturing system for machining workpieces in the following set amounts: shaft (30 000 pieces), driving gear (20 000 pieces), integral pinion shaft (20 000 pieces). The analysis of manufactural, technological and constructional characteristic made treatement plan for each workpiece. Taking into account the characteristic of the workpieces and the default amount and possibility of changes in the future, will use flexible manufacturing equipment. Using process method were grouped parts workpieces and is determined three-subject manufacturing system for a group of a workpieces ABC. By selecting the transport system, order processing and graphic display cycle, development is determined by the spatial arrangement and workflow manufacturing of each workpiece. It is selected the double row spatial arrangement of manufacturing equipment with two-way-passing stroke. This enables workpiece flow without transport between two operations. This preliminary project shows all the problems of designing the manufacturing system and the ability to solve problems in different ways in order to achieve an optimal manufacturing system.
