Abstract

The present application relates to a cutting blade based on a graphene sensor, including a cutting blade, a graphene sensor and a detection circuit. The cutting insert includes a main flank and a mounting flank. The graphene sensor includes two electrodes and a resistance grid connected in series between the two electrodes, wherein the two electrodes are arranged on the side of the installation, the resistance grid is arranged on the main flank, and the resistance of the resistance grid changes when the cutting blade is worn. The detection circuit is electrically connected to the two electrodes respectively, and is used to detect the current change at both ends of the resistance grid, calculate the resistance value change of the resistance grid according to the current change, and determine the wear degree of the cutting blade according to the resistance value change of the resistance grid. The graphene-based cutting insert can detect the wear of the cutting edge in different degrees, and can realize the real-time detection of the wear state of the cutting edge during the cutting process without being disturbed by the grid voltage or electromagnetic noise.

Description

technical field [0001] The present application relates to the technical field of tool wear monitoring, in particular to a cutting blade based on a graphene sensor. Background technique [0002] During workpiece processing, there is vibration between the cutting tool and the workpiece to be processed, and the extrusion and friction between the two will generate a lot of heat, resulting in wear of the cutting blade. Therefore, monitoring the wear of cutting inserts can ensure the quality and performance of workpieces, and at the same time provide reference data for process improvement, cutting insert design and cutting mechanism. [0003] Existing tool wear monitoring methods mainly use spindle torque monitoring, machining sound monitoring, and optical wear offset monitoring. However, the above tool wear monitoring methods are only suitable for rough machining and are easily disturbed by grid voltage and electromagnetic noise. Contents of the invention [0004] Based on th...
