Abstract:
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.

Claim (Index 13):
A method of determining a force F 0  and a torque T 0  between the work-piece and the tool of the instrumented tool of  claim 1 , the method comprising the steps of:\n (a) the multi-axis force/torque/strain/pressure sensor sensing a force F \u2227X  and a torque T \u2227X  applied by the tool to the work-piece; and (b) solving for F 0  and T 0  using the following equation: ( F 0 T 0 ) = [ R LC TSK 0 R LC TSK \ue89e \u0394 ^ LC R LC TSK ] \ue89e ( F \u039b \ue89e \ue89e X T \u039b \ue89e \ue89e X ) where vector {circumflex over (\u0394)} LC  and matrix  TSK R LC  represent displacement of origin and rotation of axes of a coordinate system of the tool with respect to a coordinate system of the multi-axis force/torque/strain/pressure sensor respectively, and where \u0394 ^ LC = [ \u0394 \ue89e \ue89e x 0 \u0394 \ue89e \ue89e z ] \ue89e \ue89e and \ue89e \ue89e R LC TSK = [ 0 0 1 1 0 0 0 1 0 ] \u0394x being displacement of a centre of the tool from a centre of the multi-axis force/torque/strain/pressure sensor in a direction parallel to a spin axis of the tool, and \u0394z being displacement of the centre of the tool from the centre of the multi-axis force/torque/strain/pressure sensor in a direction orthogonal to a spin axis of the tool.
