Abstract:
A throw-away tip with an abrasion sensor comprising:a generally planar base, one surface of the base defining a rake face, side faces of the base that intersect the rake face defining one or more flanks and one or more restricted faces, the one or more restricted faces being adapted to be fixed in abutment against a restriction face of a holder when the throw-away tip is mounted in the holder; a cutting ridge defined by an intersection between the rake face and at least one flank; a sensor line of a conductive film provided along the cutting ridge on the at least one flank in an electrically insulative relation with respect to the base; a contact region provided on at least one restricted face in an electrically insulative relation with respect to the base, the contact region being electrically connectable to an external circuit; and a connection portion provided on the base in an electrically insulative relation with respect to the base and connecting the contact region to an end of the sensor line.
