Περίληψη
Modern requirements in manufacturing industry for mechanical products of better
quality and higher accuracy machined by material removal, and the pursuit of minimization of
the production costs, in conjunction with the growing complexity of the product geometry, led
to further development of the computer numerically controlled (CNC) machine tools, and of
the respective CAD/CAM systems. However not enough progress is occurred with emphasis
on the development of computational systems, which can determine the most efficient cutting
conditions, taking also into account the dynamic behavior of the machine tool system and the
tool path planning. This paper is proposing an experimental-computational method in terms of
appropriate simulation model, which allows the selection of optimum cutting conditions in
end-milling processes, taking into consideration the workpiece surface quality, the developed
cutting forces, the vibration deflections in the cutting zone, as well as the strategy of the tool
path planning. Finally, the objective of the paper is to deliver an innovative methodology
capable to be exploited in manufacturing industry with following benefits:
• Increase of the material removal rate
• Improvement of the workpiece surface
• Increase of the cutting tool life
• Restriction of faulty products
• Reduction of costs and machining time with increase of productivity
