AUTONOMOUS MACHINING – RECENT ADVANCES IN PROCESS PLANNING AND CONTROL
Journal Title: Journal of Machine Engineering - Year 2019, Vol 19, Issue 1
Abstract
While autonomous driving has come close to reality over the recent years, machining is still characterised by many manual tasks and prone to costly errors. In this article, an overview is given about the potential of autonomous machining and uprising technologies that support this vision. For that purpose, a definition of autonomous machine tools and the required elements is presented. Next, selected elements of an autonomous machine tool, e.g. sensory machine components and control loops, are discussed. Finally, some insights into ongoing research projects regarding the use of machine learning for process planning and control are given.<br/><br/>

INFLUENCE OF LINEAR FEED DRIVE CONTROLLER SETTING IN CNC TURNING LATHE ON THE STABILITY OF MACHINING
The paper deals with the influence of linear feed drive controller setting of a CNC turning lathe on the stability of machining. A coupled simulation model of feed drive control and ball screw drive mechanics with a tra...
IN-PROCESS CONTROL WITH A SENSORY TOOL HOLDER TO AVOID CHATTER
Hydro-, steam- and gas- turbines, aircraft components or moulds are milled parts with complex geometries and high requirements for surface quality. The production of such industry components often necessitates the use of...
UTILISATION OF IOT AND SENSING FOR MACHINE TOOLS
Strong requirements for automation in the production processes using machine tools have been increasing due to lack of high-skilled machining engineers. Automation used to be utilised in mass production, but it is also n...
DEVELOPMENT OF A HIGH-SPEED MIRROR-LIKE FINISH POLISHING TECHNOLOGY FOR MINUTE PARTS BASED ON A LINEAR MOTOR
As high speed, high acceleration and stable drive on machine tools is constantly growing in demand, the use of linear motors in machine tools has increased. On the other hand, in order to achieve a high degree of qualit...
