Simulation of Cutting Process – Modeling and Applications

Cutting process plays an important role in manufacturing of a large range of products for all types of production (shop, batch and mass production). Hence the constant need of improvement and optimization of process and parameters exists. It can be expressed by two postulates: increasing of efficiency and quality. At present the significant improvement of both factors seems to be impossible without understanding of dynamical basics of cutting process. Thus research and development into realistic mathematical models of cutting process, becomes even more important than previously. Models become a useful instrument for technologist just after adapting of worked out mathematical equations for adequate technological problems. This stage is usually quite difficult and very important because it determines usefulness of model. In the chapter dynamical model of cutting process for turning was described. The model denotes two-degree-of freedom tool deflection caused by dynamical cutting force. It considers the main dissipative factors: regenerative effect and process dumping caused by dynamical limit federate. As the result of analysis, the main ranges of potential application were proposed
