Abstract: A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices.

Abstract: A hand-operated swage device includes a first hand-operated actuator and a second hand operated actuator that, when actuated together, control the sequential operation of a clamping mechanism and a swaging mechanism of the hand-operated swage device. For example, the first actuator of the swage device is disposed on a first handle while the second actuator is disposed on a second handle of the swage device. To operate the hand-operated swage device, an operator grasps the first handle with one hand and grasps the second handle with his other hand to actuate both of the actuators in a substantially simultaneous manner. Actuation of both actuators controls sequential delivery of pressurized air to a first pneumatic device mechanically coupled to the clamping mechanism and to a second pneumatic device mechanically coupled to the swaging mechanism.

Abstract: A positioned sensing device measures and/or calculates the lateral position and movement of a saw blade. These measured and calculated values are used to automatically alter the work-feed rate and/or saw blade rim speed either up or down as sawing conditions change within the work piece or between different work pieces.

Abstract: Disclosed are cutting blades for cutting tools and methods of making the blades. Such blades include tooth patterns with both set and non-set teeth. Each of the set teeth are set at an angle with respect to the jaw line of the blade, and each set tooth includes at least one surface feature that is effective to direct a portion of swarf that is produced via the cutting action of the blade into gullets of the blade such that less swarf overall is directed to the cutting surface of the objects being cut by the blade.

Abstract: Disclosed is a cutting tool with an asymmetric tooth form, and a method for making the same. Such tooth forms are useful for cutting tools such as band saw blades, circular saws, hacksaws and other saw type products. The tooth form of this invention can improve precision over prior art tooth forms by reducing manufacturing variability. The improved precision provides more consistent performance and a better quality of the cut surface. The non-symmetrical form ground tooth profiles cut designated chip profiles and thereby cut specific portions of the kerf much like a broaching application. This non-symmetrical ground tooth profile can alter the distribution of the downfeed cutting force allowing for more aggressive cutting or conversely, cutting at the desired rate with less downfeed pressure.

Abstract: A method of testing the characteristics of a file by providing a curve of the amount of material removed from a test bar as a function of the effective stroke area over which the file has been moved, the slope at a specified value of material that has been removed representing the cutting efficiency of the file and the value of the effective stroke area at such specified value representing the useful life of the file. Further, curves of the minimum filing forces needed to move the file for a selected stroke distance at selected compressive forces and of the maximum compressive forces which will not prevent a filing operation at selected filing forces can be used to determine the sharpness of a file relative to other files that have been similarly tested.

Abstract: A method for testing circular saws in which a saw to be tested is mounted for rotation at a controllable speed, a sensor being mounted opposite a surface thereof for determining the distance from the sensor to the surface. The sensor is appropriately calibrated and, when the saw is rotated at selected speeds, the output signal from the sensor is processed so as to provide a time domain response waveform and a frequency domain response waveform therefrom at the selected speeds of rotation. Certain characteristics of the saw's operation, such as the presence of low frequency "wobble" components, the width of the cutting operation, the perpendicularity of the cutting plane of the saw relative to the axis of rotation, and the development, or flatness, of the saw, are determined from the time domain and frequency domain responses.
