The user interface for a tele-machining system with operational environment transmission capability

This paper describes requirements for a user interface for a tele-machining system with operational environment transmission capability. The necessity of transmitting information concerning the operational environment requires a method for transformation of multi-axis force information to visual and auditory information. Methods for predictive display of geometrical information and auditory information to compensate for transmission time delays are also described. For tactile information presentation, an eccentric weight was used to generate vibration, whose frequency was controlled according to an index which represents machining state. Hardware and software construction suitable for multi-operator and multi-machine systems is also discussed.
