On the dynamics of high-speed milling with long slender endmills

January 1, 1998
Author(s)
Matthew A. Davies, A Schaut, Jon R. Pratt, Brian S. Dutterer
Tool deflections of high length-to-diameter ratio endmills are measured with capacitance probes during high-speed milling and compared with the predictions of regenerative chatter theory. Poincar? sectioning (once per revolution sampling) techniques are

Time Domain Modal Estimation

January 1, 1998
Author(s)
S Fahey, Jon R. Pratt
In a previous technical feature,2 we described some motives for performing structural dynamic tests and subsequently reviewed some frequency domain techniques for uncovering modal parameters. This time, we take up some applicable time domain algorithms by
