Abstract

The texture of machined surfaces can be predicted from knowledge of the vibratory behaviour of the machine-tool-workpiece system. This study is initiated to develop a generalized computer based simulation for predicting surface roughness for and given conditions which takes into consideration the important parameters influencing the dynamic behaviour of the machine-tool-workpiece system. The parameters considered in the simulation are: machining variables, tool and workpiece variables, and the mass, stiffness and damping of the machine-tool-piece system. Matlab SimulinkTM is used to interactively perform the simulation in a user-friendly, effective and efficient manner. The effects of machining variables and tooling characteristics on the surface generation are investigated through simulations. Turning trials have been carried out to evaluate and validate the presented approach and simulations. The proposed approach contributes to comprehensive and better understanding of the machining system and is promising for industrial applications with particular reference to the optimization of the machining process based on the product/component surface functionality requirements.
