The Smoothed Particle Hydrodynamics (SPH) is a meshfree simulation method which allows to describe the machining process of the nickel-based alloy Inconel 718. This paper analyses the accuracy of a developed simulation model for an orthogonal turning process. The simulation results show the occurring process forces. Subsequently, the model is extended with a variable chip thickness to consider the different engagement condition during a peripheral down milling process. The model allows to investigate the influence of geometry parameters of the cutting edge for possible tools designs with little economic and financial expenses.
