Experimental examination of the gyroscopic and rotary inertia effects on the chatter boundary in a milling operation is the chief aim of this article. The equations of motion of the tool vibration are derived based on Timoshenko beam theory and Hamilton principle by considering gyroscopic moment, rotary inertia, velocity-dependent process damping and radial immersion effect. For a range of dept...

This paper presents the design of an over-the-phone, non-taskoriented, conversational spoken dialogue system character created to chat with users about himself and entertain them. Focus is on techniques used in personality modelling of the system character, how his mood changes based on input, and how this is reflected in his output. Experience with a first version of the system and planned imp...

Ultra-precision milling with an aerostatic high-speed spindle and a single-crystal diamond micro-tool is promising for the fabrication of miniaturized complex parts. While tool chatter occurring in processes has substantial effect on machined surface formation, fundamental understanding behavior ultra-precision essentially required achieving ultra-high finish. In this paper, through combination...
