Instrumented tools for monitoring interaction dynamics during contact task

摘要

An instrumented tool for surface finishing of a work-piece, the instrumented tool comprising: a tool configured to be spun and brought into contact with the work-piece while spinning; a spindle configured to provide a spinning torque to spin the tool; a flexible coupler provided between the spindle and the tool to transmit only spinning torque of the spindle to the tool; a rigid connection provided between the spindle and the tool in parallel to the flexible coupler; and a multi-axis force/torque/strain/pressure sensor attached to at least the rigid connection; wherein the rigid connection and the multi-axis force/torque sensor are decoupled from spinning of the spindle and the tool, and wherein the multi-axis force/torque sensor is configured to measure at least one of: contact force and torque between the tool and the work-piece.
