ABSTRACT

Micro mechanical machining is applied in a wide range of industrial fields thanks to its flexibility but the tool-material interaction and the chip formation phenomena in the microscale still have not been completely investigated and understood. The so-called quick-stop experiments are an useful instrument to carry out this kind of studies since they allow to freeze the cutting action in a steady condition and to study the occurring phenomena. A new micro quick-stop device (QSD) has been designed to fit the typical microscale cutting requirements, to be equipped with systems and sensors suitable to validate each quick-stop experiment and, moreover, to achieve a good repeatability. Some preliminary experiments have been carried out to prove the effectiveness of the developed system.

Keywords: Quick-stop device, Micromachining, Chip formation, Orthogonal cutting.
