Design and Analysis of a 5-Axis Gantry CNC Machine Tool

Abstract

In this study, design and analysis of a gantry-type 5-axis CNC machine tool is presented with experimental results on a manufactured prototype. Critical points in the design of a large-scaled and heavy-duty machine tool is discussed. Moreover, FE analysis results is also presented with detailed discussion. The measurement results on structural dynamics is shown together with the FE results. Furthermore, the final performance of the machine tool is demonstrated thorough position and velocity measurements of the axes.

Control Parameter Optimization-Based Machining Control Technology of State-of-the Art Computer Numerical Control Machine Tools

“…At present, the current loop, speed loop and position loop of three closedloop PID control technology are widely used in the servo system of CNC machine tools. However, the efficiency of this PID parameter tuning method is not high, and the work experience of the tuning engineer is required to be high, because the design and parameter tuning of AC servo system is particularly important [26][27][28]. In order to analyse the dynamic and static quality of AC servo system, a mathematical model, usually ordinary differential equation, is needed to describe the dynamic physical law of the system.…”
