Abstract: An in-process kerf measuring device and method of using thereof, for measuring a kerf made from a cutting device. The device includes a taper gauge having a top and bottom, the taper gauge being a predetermined shape and size and capable of probing the kerf. The device also includes a spring coiled around the taper gauge, a shaft having a top and a bottom, the top of the shaft is in mating relation to the bottom of the taper gauge, a horizontal connecting plate having a resting position, the bottom of the shaft is rotatably attached to the horizontal connecting plate. The device also includes a stroke means, where the stroke means is in connected relation to the horizontal connecting plate, a measurement means for measuring the kerf and a means for actuation of the device.
