METHOD FOR AUTOMATICALLY RESHARPENING A KNIFE

One variation of a method for automatically re-sharpening a knife includes: receiving a knife at a vice; during a scan cycle, scanning the grind head along a blade of the knife from an initial longitudinal position proximal the vice toward a longitudinal end position and recording a sequence of vertical positions of segments of an edge of the blade at various longitudinal positions of the grind head based on outputs of a sensor arranged in the grind head; calculating a blade profile for the knife based on the sequence of vertical positions; and, during a grind cycle, actuating a grind wheel inthe grind head and pitching the grind head while driving the grind head longitudinally along the blade to maintain an axis of the grind wheel substantially parallel to segments the blade profile corresponding to longitudinal positions of the grind head, relative to the vice. 一种用于自动重新磨刀的方法的一种变型包括在虎钳处接收刀；在扫描周期中，沿着刀的刀片从虎钳近侧的初始纵向位置向纵向结束位置扫描研磨头，并且基于布置在研磨头中的传感器的输出，记录在研磨头的各个纵向位置处的刀片边缘的各段的竖直位置序列；基于竖直位置序列计算刀的刀片轮廓；并且在研磨周期中，致动研磨头中的
