AI Technical Summary
Technical Problem
Existing knife sharpening processes are inefficient and often require manual intervention, lacking a systematic approach to determine the optimal cutting edge shape and material removal for different types of knives.
Method used
A method involving a scanner to measure knife dimensions, analyze its shape, and control the grinding process to automate the sharpening, ensuring precise material removal and achieving a target cutting edge shape without manual intervention.
Benefits of technology
Enables fully automated and efficient knife sharpening with optimized material removal, ensuring high-quality cutting edges and reduced machining time, while preventing damage by detecting defects before sharpening.

Abstract
In a method for sharpening a knife, dimensions of the knife are measured using a scanner. A desired shape is then determined by knife-edge shapes which are obtainable by removing material being determined as straight lines or curves. A machining quality is then determined and, of the possible knife-edge shapes, the one is selected which corresponds to the machining quality before, in order to achieve the desired shape, the knife is ground until the desired shape is reached.
