Experimental Characterization of Robot Arm Rigidity in Order to Be Used in Machining Operation
Jean-Yves K'Nevez, Mehdi Cherif, Miron Zapciu +1
Attempts to install a rotating tool at the end of a robot arm poly-articulated date back twenty years, but these robots were not designed for that. Indeed, two essential features a…
Self-excited vibrations in turning: cutting moment analysis
Olivier Cahuc, Jean-Yves K'Nevez, Alain Gérard +4
This work aims at analysing the moment effects at the tool tip point and at the central axis, in the framework of a turning process. A testing device in turning, including a six-co…
The Regenerative Vibrations Influence on the Mechanical Actions in Turning
Claudiu-Florinel Bisu, Raynald Laheurte, Alain Gérard +1
In manufacturing during the cutting process the appearance of vibrations can not be avoided. These vibrations constitute a major obstacle to obtain a greater productivity and a bet…
Analyzes Geometry of Part and Chips at the Time of Regeneratives Vibrations
Claudiu-Florinel Bisu, Jean-Yves K'Nevez, Alain Gérard +1
The actions of cut applied to the elastic system cause relative displacements tool/part, which induce a rise in the temperature in the components of the machine tools, its environm…
Optimization and Dynamic Characterization System Part in Turning
Claudiu-Florinel Bisu, Constantin Ispas, Alain Gérard +1
The appearance of the self-sustained vibrations corresponds to the dynamic instability of the machine tool. An experimental device and a model were designed to characterize the cut…
Using Tracking Analysis and Predictive Maintenance in Order to Obtain Dynamics of Machine Tool Spindle
Miron Zapciu, Jean-Yves K'Nevez, Alain Gérard
Predictive maintenance is directed towards recognizing the earliest significant changes in machinery condition. Contrasted with protective condition monitoring in which fast respon…
