Modelling and optimisation of up-and down-milling processes for a representative pocket feature
The main aim of this research is to improve the efficiency of CNC machining by better process planning, improved accuracy and reduction of time when machining complex pocket features. The mathematical models, simulation and optimisation techniques developed in this study have been experimentally verified for the first time for up- and down-milling under various cutting conditions. The results demonstrated that the variable cutting conditions have significant advantages over milling with constant cutting conditions in the reduction of the cutting forces and radial cutting tool deviation, and thus on surface errors.
