Impact of an intelligent tutor on risk and sound perception in CNC machining

It appears that virtual reality training, for systems that behave in a similar fashion to a real system, can support proper decision making. However, there is a void of research showing under what conditions virtual training can support decision making. As the nature of industrial tasks has shifted from motor and procedural tasks to more cognitive and judgment based tasks, some aspects of the job may not be frequently practised or called upon. Many times, human errors in industry are frequently shown to coincide with computer-numerical-control (CNC) machining conditions that are infrequently encountered. Knowledge and auditory cues for different machine feed rates and depths of cut are built into the existing knowledge base of a virtual training system. Results of the current study, still in progress, are presented
