Abstract

Technological progress has led to increased demand for small components with tiny features, which cannot be achieved through conventional machining. Industrial application of processes based on microcutting is limited by some issues concerning the geometrical scale. The process performance is significantly affected by milling ma- chine, tool holder, tool, workpiece material microstructure, workpiece fixtures, and process parameters. At pres- ent, an ultimate micromachining assessment procedure is not available. This study aims to propose and conduct an experiment on a testing procedure for micromilling. The set up to be implemented and the output to be con- sidered are defined and described. Three major stages are identified: estimation of the effective bandwidth of the load cell-tool holder system, the milling machine natural frequency measurement, and micromilling test execu- tion. The entire procedure is performed, and its robustness is demonstrated.
