... is transformed into the principle modal directions of the rotating tool. The process damping is modeled as a linear function of vibration velocity. The dynamics of the milling system is modeled by a time delay matrix differential equation with time varying directional factors and speed dependent elements...

... the grinding force acting on the blade surface. A differential equation is constructed, and the related numerical solutions are provided to describe the blade deflection behavior in the sawing process. The study then discusses the influences of the “size effect,” workpiece length, workpiece speed and feed rate...

...Tamás Insperger; Janez Gradišek; Martin Kalveram; Gábor Stépán; Klaus Winert; Edvard Govekar A two degree of freedom model of the milling process is investigated. The governing equation of motion is decomposed into two parts: an ordinary differential equation describing the periodic chatter-free...
