Abstract
With the application of adequate chip separation theories, ultraprecision machining can be planned with better accuracy, more economically and can be better controlled, respectively. For in some cases it is about machining of submicron accuracy (the separated chip cross sectional area is of nm2 dimension), therefore, traditional cutting theories that describe the separation of the bigger chip-cross sections are not sufficiently accurate. Creation and implementation of new theories will be needed, such as finite element method (FEM), atomic or molecular dinamical models (MDS).
Purpose of the research work: With the aid of computer simulation to give a statistical estimation of the changes occuring on the workpiece and tool, of the probable mechanical and geometrical properties, of the development of the cutting force, etc.
