Abstract

The paper refers to a method for online control of dynamic stability in cutting processes, stability characterized by the absence of relative self excited vibration between tool and part, and also to the necessary equipment for the implementation of this method on machine tools for mass production of batches of different products. . The method has the following advantages:
i) ensuring the permanent use, in optimal terms of dynamic stability, of the machining system processing capacity;
ii) it can be applied to all machining systems based on cutting, where the dynamic instability exhibits self-excited vibration between tool and part;
iii) in the designing stage, the method allows satisfying both the specific dedicated machining systems requirements and the specific universal flexible or dedicated machining systems;
iv) when put in use, it requires a smaller number of settings, to grant changes in terms of machining system structure or operation
The necessary equipment for implementing this method can be designed asan independent unit that can be attached to the machining system, in which case its construction should make it rather common, but also as a dedicated and integrated CNC machining system unit. The paper presents a study of the method application for turning operation.
