Machine Tools Mechatronic Analysis

Abstract

High-speed machine tools show close interaction between the dynamic behaviour of the mechanical structure, drives, and numerical control. In order to support the designer of high-performance machines, a new analysis based on an integrated holistic mechatronic optimization technique is proposed and compared with the traditional approach. The proposed approach is applied to a three-axis milling machine for dies and mould production.

An integrated prediction model including the cutting process for virtual product development of machine tools

“…Also, the complexity of model can be very high, because interface nodes are increased to connect kinematic chains of flexible bodies (i.e. connection between ballscrew nut and ballscrew shaft, connection between linear motion block and guide way) [18,19,21,22].…”

Control Parameters Auto-tuning for Bi-axial Servo Feed System

“…On the other hand, these methods hardly cope with the dynamics mismatching between motion axes. However, if the dynamics mismatch between motion axes, it is difficult to attain the desired contour accuracy, even if the following error of single axis servo feed system is desired performances [7] [8]. Therefore, it is essential to matching dynamics for bi-axial servo feed system.…”

A new numerical calculation method for the characteristics of hydrostatic slide

“…So, in the state-of-the-art technology, hydrostatic slides are applied in almost all the ultra-precision machine tool. At design stage of the slide, the carrying capacity and the stiffness of hydrostatic slide is an important value [5] . The traditional calculation method of slide stiffness used in engineering is an approximate solution, the accuracy is low.…”
