A SYSTEM FOR DETERMINING INDIVIDUAL CUTTING EDGE GEOMETRY BASED ON DETERMINING CUTTING BEHAVIOR VIA A WEAR REFERENCE SURFACE.

Abstract

The invention is a system for determining the user-specific target cutting edge geometry (8) in kitchen knives and similar hand-held cutting tools according to the user's actual or standardized cutting behavior, consisting of a test carrier base (1) on which the cutting operations are performed, a wear reference element (2) attached to the base in a removable manner and having a predetermined wear characteristic, positional reference markers (3) enabling the determination of the positional distribution of wear, a wear level determination structure (4) enabling the determination of the contact level by means of distinguishable wear layers (41, 42, 43), and a reference cutting tool (5) with a known geometry.It is related to the cutting edge geometry determination system, which includes the wear data evaluation unit (6), which creates the user’s cutting behavior profile (13) by determining the regional wear values ​​from the regional wear marks (12) created by the repeated cutting operations of the reference cutting tool (5), and the geometry determination unit (7), which converts the said cutting behavior profile (13) into the user’s specific target cutting edge geometry (8), including cutting edge curvature, linear cutting edge section length, heel geometry and / or tip geometry, using the calibration relationship created for the known geometry of the reference cutting tool (5) and the determined wear characteristic of the wear reference element (2).
