Abstract: A T-Nut for use in a machine tool having a tooling plate with an inverted T-shaped channel. The T-Nut comprises a central body having oppositely inclined faces each including an opening forming a cavity extending through the central body, and first and second wedges in slideable communication with the central body inclined faces. Each of the wedges have wings extending laterally beyond the central body to engage upper surfaces of the channel lower wide portion and include a clearance hole extending through a length of the wedge. A rotatable actuation member abuts the first wedge at an end opposite the first wedge mating surface and is internally threaded for a distance from one end thereof. An externally threaded cylindrical shaft is engaged with the internal threads of the actuation member and extends through the first and second wedge clearance holes, the shaft being secured to and non-rotatable with the second wedge.

Abstract: The present invention adds gain and phase into a canonical second order system in order to mitigate the adverse effects of unwanted resonance, where the gain is added to the forward path of a control loop of the system and is a ratio of the square of the system and mechanism frequencies, and the phase lead (H-factor) is added to the feedback path of the control loop of the system and is a complex ratio of these frequencies which includes a dc-component (Hdc) and a zero- or pole-component. By adding gain and phase lead, which is contrary to current approaches to addressing resonance, the present invention achieves the desired result of resonant free application in a canonical resonant-prone system of second order, and the methodology is applicable to higher order systems.
