摘要

The ability to manufacture at the micrometric and even nanometric precision is in strong demand today in view of the increasing need to both reduce the size and expand the functionality of parts and products in many industrial and commercial sectors. Reducing the overall size of machine tools is an effect to address the need of micrometric scale precision manufacturing. Generally there are two categories of benefits that can result from the miniaturization of machine tools: one is economical and the other technical. This paper concentrates on the machine tool technological performance benefits in the context of static rigidity, dynamic stability, and thermal resistance as functions of machine tool size. Finite element analysis has been performed to quantitatively relate the machine tool major dimensions to the resulting forced deflection, dynamic damping, natural frequency, and multi-axis thermal deformation. The analysis leads to the assessment of the technological benefits of machine tool miniaturization in the terms of machine stiffness, accuracy, and achievable precision.
