Hybrid cutting process combines different physical mechanism to achieve an extended performance of the cutting process. Yet, adding supporting systems and consumptions must be seen critical because they are not directly adding value, which means that they are consumers only. It is essential to analyse and optimize their use in relation to the superior process development. Thereby the two physical mechanisms and their interactions result in many parameters to be handling for successful process setup. Different approaches, e.g. design of experiments or finite elements methods, exist to analysis and optimize such complex machining processes. Both approaches will be shown by analysis of drilling with cryogenic cooling and laser-assisted milling. Finally, a new combined methodology will be presented in general.
