Machine-tool as eny other product of human activity has to meet some functional and operational parameters. The aim of the machine-tools is to enable technological working processes of machining and forming opera-tions, which give the product their shapened size. The working processes are mechanical procedures and they can be ensured by corresponding types of machine-tools (forming, machining).
The machine-tool has to be satisfactory mainly from the manufacturing (i.e. machining and finishing) point of view. Other view points and criteria include the quality of produced components and entire machines. It is very important to ensure operational reliability and durability of tools and individual parts of machine.These properties of machine-tools are given by the dynamic properties of their mechanical systems.
