Synopsis:

Systematic view on production machines and systems. Requirements on production machines. Technological characteristics of production machines (PM). Static and dynamic stiffness. Drives of the production machines. Carrying system. Work fixtures. Properties of PM. Placement of the machines on the basement. Machines with hand control and program control - classification, design and calculation of different types and class of machines. Essential features of numerical controled machines. Production systems for cutting and forming - flexible, nonflexible and partly flexible. Carrying system of machine tools (MT), requirements, main carrying bodies, joints and their components. Fixed joints (linear and planar case). Movable joints (theoretical basics, rectilinear and circular guides, spindles and their mounting). Dynamic stiffness, systems with two degrees of freedom and n degrees of freedom (normal and forced oscillation, with and without damping, in more directions), self-excited oscillation, dynamic characteristics, placement of the machines on the basement. Thermal, dynamic and noise behaviors, working accuracy and efficiency of MT. System of automatic tool changing and automatic workpiece changing. System of lubrication, cooling, MT controlling and chip conveying. Numerical controlled MT. Classification of NC MT by different aspects. Characteristic attributes of the design. Flexible production cells, systems and lines. Single-purpose and reconfiguratable MT. Parallel structures of MT.
