Abstract: A system for inspecting first and second surfaces of a cutting member, such as a tooth of a carbide tooth circular saw blade, includes a support for carrying the cutting member, the cutting member being movable relative to the support to position the surfaces to be inspected within an inspection zone. First and second video cameras mounted on the apparatus relative to the inspection zone provide output signals representative of the images of the first and second surfaces, respectively. A computer responsive to the output signals generated by the first and second video cameras analyzes the output signals and calculates selected attributes of the surfaces presented for inspection. A frame grabber captures video images of the surfaces. A first video monitor coupled to the computer displays images of the surfaces being inspected while a second video monitor coupled to the computer displays graphical data relating to selected geometrical attributes of the surfaces.

Abstract: A method of brazing a strob insert to the trailing edge of a slot in a strob circular saw blade, the strob insert having first and second, opposed, substantially parallel surfaces, the first surface of the strob insert to be brazed to the edge, comprises the steps of placing the strob insert on an electrode with the second surface of the strob insert in contact with the electrode in heat transfer relationship therewith; applying brazing paste to the first surface of the insert; positioning the electrode so that the first surface of the insert is in a brazing position relative to the edge; and passing an electrical current through the electrode to resistively heat the electrode to a temperature sufficient to cause brazing of the first surface of the strob insert to the edge.
