forces identification - Opis:
- The calculations of machining stability limit currently known do not provide a precise prediction of chatter-free cutting conditions. The inaccuracy is probably caused by mathematical models of dynamic forces acting on the cutting process during unstable machining. These models need to be modified. A new analysis of experimental data measured by one of the authors, M. Poláček, in the 1968-1974 period, forecasted an existence of several dynamic forces, which are mutually phase-shifted, thus complex. This fact has not been thoroughly investigated previously. As the assumed forces cannot be calculated from any equations, they must be identified experimentally. This research paper proposes a theoretical method of an experimental identification of these forces. The new model is intended to be used in the future for the development of a more accurate calculation of stability diagram.
