Study on human-oriented interface for CNC machine tools

This paper deals with fundamental research on the development of human-oriented interface for CNC machine tools which allow workers to feel pride and pleasure in making full use of their ability in manufacturing. As a first step toward human-oriented CNC machine tools, three information feedback channels designed to provide workers with much useful information on machining phenomena have been proposed. They are the machining phenomenon visualizing system (MPVS), the machining vibration display dial (MVDD) and the machining conditions display system (MCDS). These systems have been evaluated by inexperienced and skilled operators of CNC machine tools using the information integration method, The results show that the combination system of MPVS, MVDD and MCDS greatly improves workers' satisfaction in CNC lathe work.
