“…To prevent the risk to develop extremely complex numerical models that do not represent the real system, it is necessary to simplify the preliminary structure, as reported in Marten (1962) and Zatarain (1998). Basically, the system can be divided into functional subgroups, linked to each other by lumped masses or other parameters.…”

Considering the customers' demand for high quality products, surface finishing represents an extremely delicate phase in the production of ceramic tiles. In these terms, stiffer machinery can be considered a practical response to the need of accurate manufacturing processes. This research is focused on investigating and improving the (elasto)dynamic behaviour of a large machine tool, used for polishing and lapping ceramic tiles. A modal analysis was realized comparing natural frequencies in respect to different design solutions. The stiffness optimization was obtained by changing the structural design.

“…Coupled modeling techniques employing the reduced FE models of the machine tool structure have been developed for describing the ball screw feed drive and machine tool interaction. Commonly the coupled models rely on one kinematic configuration and application of modal or CMS reduction techniques [6][7][8][9]. Importance of proper prediction of higher frequency range dynamics of feed drive mechanical structure with respect to feed drive control parameters shows [10].…”

Quick calculation of machine tool dynamic response represents one of the major requirements for machine tool virtual modelling and virtual machining, aiming at simulating the machining process performance, quality, and precision of a workpiece. Enhanced time effectiveness in machine tool dynamic simulations may be achieved by employing model order reduction (MOR) techniques of the full finite element (FE) models. The paper provides a case study aimed at comparison of Krylov subspace base and mode truncation technique. Application of both of the reduction techniques for creating a machine tool multibody model is evaluated. The Krylov subspace reduction technique shows high quality in terms of both dynamic properties of the reduced multibody model and very low time demands at the same time.

“…Altintas, Y. and Brecher, C. et al proposed a new design procedure with virtual prototypes that shorten design time (3) . Zatarain, M. Lejardi, E. and Egana, F. cut calculating time in stiffness analysis using condensed mass and stiffness matrices instead of the huge matrices, which obtained by the finite element method (FEM) system (4) . However, most researchers have considered the stiffness of the machine tools structures only in detail design stage.…”

This paper presents the improvement of design efficiency of machine tool structure in the conceptual and basic design stage. An interactive system has been developed for designing machine tool structure in this study. The key point in the interactive system is that a set of beam elements are assumed to compose the total structure of machine tool because it is easy to analyze the static, dynamic and thermal features. In this interactive system, a conversion procedure also has been developed. By using this conversion procedure, the selected beam structure of machine tool can be converted to an actual structure, completing conceptual and basic design. Consequently, using the interactive system allow, designers can complete the machine tool structure design in a shorter time with higher efficiency. The goal of the interactive system is to assist designers to quantitatively and quickly select a superior machine tool structure.
