Performance validation of a micro quick-stop device

Chip removal is one of the most flexible and widely exploited processes in the microscale, but it is still not completely understood and controlled since the process cannot be effectively described simply downscaling macroscale models. The so-called quick-stop experiments are an invaluable support to study the tool-material interaction in the microscale, since they allow to freeze the chip formation in its regime condition by abruptly stop the cutting action. In this paper a new quick-stop device (QSD) is proposed by the authors to be used within the typical microscale cutting requirements; an especially developed sensor has been used to validate the device by means of suitable indexes.
