OPTIMIZATION OF MACHINING CONDITIONS FOR TURNING CYLINDRICAL STOCKS INTO CONTINUOUS FINISHED PROFILES

The optimization problem involving straight turning operations for bar components with constant finished diameters has received extensive at tention. In the real-world turning processes on a computer numerical c ontrol (CNC) machine, the cylindrical stocks are frequently machined i nto their desired continuous profiles. Such turning processes require not only straight turning but also face turning, taper turning and cir cular turning to complete the removal of stock. However, machining mod els proposed in the literature do not simultaneously consider these tu rning operations to optimize machining conditions (parameters). This s tudy formulates a machining model to optimize the machining conditions for turning cylindrical stocks into continuous finished profiles, the reby extending the applications of machining optimization. The usefuln ess of the developed machining model is finally established through a test example.
