Abstract
Trochoidal path increases productivity, tool life and reduces cutting forces compare to classical slot milling. Consequently, this strategy is well adapted to improve the milling performance in refractory alloy such as Inconel 718. The tool path complexity affects the tool radial engagement and axes dynamic, so it appears difficulties to perform such strategy. Therefore, this article deals with an analytical approach of trochoidal modelling to determine the theoretical radial depth of cut, cut thickness, cutting forces and machine tool behavior in function of the different methods to program the trochoidal trajectory. Finally, this methodology allows the optimization of geometrical and kinematic parameters for trochoidal milling of Inconel 718.
