Abstract. In practice, we deal with static designed couples frequently. Construction engineers use them so they can upscale rigidity of product. In paper are described principles how to change after effects of problematic assembly in often used feed couples which use to be statically designed. Important problem in assembly is repeatable precision, mainly in construction of assembly lines. By imprecision of robot which inserting shank into the hole and by imprecision of position of hole in carrier shank won't be successfully inserted. In article are shown reasons and security approach of repeatable precision in assembly operations executing.

Abstract. This paper deals with assumption that simulation is the only reliable method for manufacturing and assembly systems profiling. Simulation is essential software tool that improve design and planning of complex automated manufacturing and assembly systems. Systems with high level of complexity need to be tested even before they are constructed in real manufacturing plant.

The engineering production is currently characterized by frequent changes. These changes are caused because the life cycle of products is shortened. Producers must introduced the upgraded products in a shorter interval. In this article we will focus on identifying the possibilities of production innovation in the flexible manufacturing system. An analysis of the production possibilities of one of the production machines in the flexible production system will be carried out. This production machine is a lathe that produces one basic part of the finished product. We will determine what variants of this component can be manufactured without changing the physical configuration of the machine.
