The determination of cutting tool profiles for machining operations with coupled rotational kinematics like gear and screw generation can be a complex task which is executed by either numerical or analytical methods. The cutting tool profile for whirling is derived from process parameters and desired workpiece geometry by both a numerical dexel-based model and an analytical model based on the condition of tangential motion. The models are adapted to a process variant of whirling with synchronized rotation of tool and workpiece and compared regarding accuracy, computation time and geometrical flexibility.

The objective of this work is presenting the foundation of a true integration of mechanical surface modification and machining. This “fusion” entails mechanical surface modification parallel to the cutting process using the cutting insert as tool. While it may seem, that something similar can be achieved through classical vibration assisted machining (VAM), this is definitely not the case. The resulting relative velocity between cutting insert and workpiece will ensure the process to be firmly rooted in cutting rather than hammering of the workpiece. Since creating a setup suitable to address this issue is a big challenge in itself, it is prudent begin by establishing the general feasibility of the process. The first priority is therefore proving that cutting inserts can be used to induce surface layer states similar to those achieved by MHP-processes. The presented work addresses this validation of mechanical surface treatment using cutting inserts regarding topography, residual stresses and work hardening by model experiment.
