This paper is an endeavour to critically appraise the existing methods used for real-time simulation of machine tool dynamics with the emphasis on modelling and simulation of the dynamic behaviour of CNC machine tool feed drives and mechatronic systems for machine tools. The actual approaches for linking the feed drive models with structural models for CNC machine tools are examined. Also the f...

The choice of the machine tools is one of the considerations of manufacturing companies which depend primarily on machining process, by deciding how a finished product will be manufactured. The activity of tools choice is established in geometry of machining features, but it also has a direct impact on workability and execution of machine-tool. We propose in this paper an integration module of ...

Computer numerical control (CNC) involves machines controlled by electronic systems designed to accept numerical data and other instructions, usually in a coded form. CNC machines are more productive than conventional equipment and consequently produce parts at less cost and higher accuracy even when the higher investment is considered. This article proposes an educational scheme for designing ...

air spindles are one of the main elements of precise machine tools. vibration of these spindles is one of the vital issues necessary for investigation. among parameters which influence air spindle vibrations are rotational speed, compression air method, input nozzle diameter, air gap pressure. in this study using ansys, the effects of air gap thickness on air spindle vibrations have been invest...

Hard real-time applications in safety-critical domains – namely avionics, automotive, and machinery – require high-performance and timing analysability. We present research results of the parallelisation and WCET analysis of an industrial hard real-time application, i.e. the control code of a large drilling machine from BAUER Maschinen GmbH. We reached a quadcore speedup of 2.62 for the maximum...
