Apparatus for cutting material with knife edge offset compensation
The granted patent (Publication Number: US11897075B2) discloses an innovative apparatus designed for cutting materials with compensation for knife edge offset. The apparatus includes a base frame with a planar work surface, a gantry assembly with a cutter toolhead frame, a moveable knife, an actuated arm, a computer controller for controlling movements, an abrasive sharpener for sharpening the knife, and a sensor to determine the distance between the cutter toolhead frame and the actuated arm during sharpening. The computer controller adjusts the movements of the knife based on the knife edge offset to enhance cutting accuracy. Additionally, the apparatus features a reciprocating knife and an abrasive sharpener with two abrasive wheels acting as probes in contact with the knife.
Furthermore, the patent claims detail additional functionalities of the apparatus. The computer controller can determine when the knife needs replacement by comparing the knife edge offset to a stored threshold value. It also has the capability to adjust the pressure of the abrasive sharpener to ensure consistent material removal from the knife. Moreover, the computer controller can identify when a new knife has been installed by comparing the knife edge offset to a stored value. These features highlight the advanced technology integrated into the apparatus to optimize cutting precision and efficiency, making it a valuable tool for various industries requiring accurate material cutting processes.
