Physical simulation of the deflection in turning of thin disk-shaped workpieces

The machining of a thin disk-shaped workpiece is a problem commonly encount ered in the aeronautics industry. Generally the successful machining of a t hin disk requires reinforcement by plaster This reduces the productivity an d increases the production cost. It is recognised that the suitable control of the cutting force to limit the maximum deflection of the disk within a certain value for each leading allows the machining to be successfully carr ied out without any plaster reinforcement. Modelling and computer-simulatio n of the deflection of a thin disk-shaped workpiece during turning are thus developed. The results of the simulation are discussed.
