Abstract: A smart tool system may include at least one assembly of a tool holder and a tool, and a tooling machine configured to rotate the at least one assembly to cut a workpiece. The tooling machine may have a spindle to which the tool holder may be selectively attachable, and a controller configured to rotate the spindle at a spindle speed. The smart tool system may also include at least one database configured to store vibrational data relating to at least one of the at least one assembly and the tooling machine. The smart tool system may further be configured to determine an optimum operating value and/or range of optimum operating values of at least one parameter for the tooling machine based on the vibrational data. The optimum operating value(s) provide for minimized or no chatter when cutting the workpiece.

Abstract: An assembly of a tool and a tool holder may include the tool, which may have an elongated body with a socket, and the tool holder, which may have a body with a first bore configured to receive at least a portion of the elongated body, and a second bore substantially transverse to the first bore. The assembly may also have an impinging member including a body having an end with a radial surface. In an assembled state, a portion of the elongated body of the tool may be positioned within the first bore of the body of the tool such that the socket and the second bore may be substantially aligned, and the body of the impinging member may be positioned within the second bore with the radial surface pressed against the elongated body in the socket at a predetermined torque.
