A Review on Modeling Technology to Machining Simulation

Machining simulation is one of the important applications of computer simulation in modern mechanical manufacturing industry. It is of great significance to produce quality parts more quickly and economically. Modeling is the key aspect of machining simulation, and it is also one of the vital criteria to the simulation system evaluating. Up to now, there are three existed modeling methods to machining simulation mainly, which are analytical modeling method, finite element modeling method and molecular dynamics modeling method. The principle and status of those methods are introduced in detail, and their advantages and current limitations are discussed as well. Then, the developing trend of modeling technology to machining simulation is presented.
