Sawbenching assembly and method
A sawbenching assembly for reworking a sawblade supported by an anvil to flatten the sawblade is provided. The assembly includes an articulated tool arm with a tool arm support, and a scissors linkage arm having first and second ends, the first end pivotally connected to the tool arm support for rotation about a first axis, the second end vertically movable. The assembly also includes a user-operated actuation device connected to the articulated tool arm, and a hammer assembly pivotally connected to the second end of the scissors linkage arm for rotation about a second axis and vertical movement with the second end of the scissors linkage arm, the hammer assembly having a user-actuated hammer with an impact surface positionable at positions on the sawblade by three-dimensional manipulation of the hammer assembly supported by the articulated tool arm. The user-actuated hammer is actuated in response to engagement of the actuation device.
Cutting apparatus capable of detecting configuration abnormalities of a cutting blade
A cutting apparatus includes a management unit having a measuring unit for measuring an amount of light emitted from a light emitter and received by a light receiver while a cutting blade is positioned between the light emitter and the light receiver, a measured waveform forming section for forming a measured waveform representing the configuration of an outer circumferential region of the cutting blade, and an ideal waveform recognizing section for recognizing one of the comparative waveforms that has the greatest number of waveform regions similar to the measured waveform as an ideal waveform, a difference calculating section for calculating the area of a region where there is a difference between the measured waveform and the ideal waveform.

Methods of Producing Saw Blades
The present disclosure provides a method of producing a saw blade (10), comprising providing a saw blade blank, comprising a circular blade base body (100) with radially extending teeth (101), said teeth being in an initial position, in a first bending step, bending at least some of the teeth (101), such that the teeth are plastically deformed, towards an axial direction (A) of the saw blade blank, to an intermediate axial position (N), and in a second, subsequent, bending step, bending said at least some of the teeth (101), such that the teeth are plastically deformed, towards an opposite axial direction (A) of the saw blade blank, such that the teeth arrive at a final axial setting position (N). In the method, the intermediate axial position (N) is axially beyond the final axial setting position (N).

Method and apparatus for removing a knockout
An apparatus for removing a knockout region from a saw blade includes an elongate body having a center axis. A distal end of the elongate body can include a head, having a concave region, wherein the concave region has a fulcrum section. A slot includes a first surface and a second surface opposite the second surface. The first surface and the second surface preferably are separated be a width greater than the thickness of the saw blade. The slot is positioned rearward of the concave region and is angled at a substantially acute angle relative to the center axis. The concave region is sized and shaped such that the fulcrum section contacts a first face of the saw blade and the slot is sized and shaped such that the first surface of the slot contacts a second face of the saw blade. Preferably, the fulcrum region engages the first region and the slot engages the second portion at the same time.
