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…
Regeneratives Vibrations Analyzes On The Part And Chip
Constantin Ispas, Claudiu-Florinel Bisu, Alain Gérard +1
The actions of cut applied to the elastic system generate relative tool/part displacements, which induce a temperature increasing in the components of the machine tools, its enviro…
Three-Dimensional Dynamic Cutting Model
Constantin Ispas, Claudiu-Florinel Bisu, Alain Gérard +1
The determination of a dynamic law of cut is complex and often very difficult to develop. Several formulations were developed, in very complex ways being given that 3 AD crosses fr…
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…
