Description

technical field [0001] The invention relates to the technical field of CNC machine tool wear measurement, mainly a method, system and device for measuring tool wear, and in particular to an on-site measurement device and method for cutting tool wear used in manufacturing the Internet of Things. Background technique [0002] In the metal cutting process, as a part in direct contact with the workpiece, cutting tool wear is a ubiquitous and inevitable phenomenon, and it continues to increase with the increase of processing time. With the rapid development of aerospace technology, higher requirements are put forward for the material, structure and machining accuracy of parts. Aerospace difficult-to-machine materials have the characteristics of complex structure and large removal amount. Therefore, more requirements are put forward for cutting tool wear measurement. high demands. According to industrial statistics, the proportion of parts scrapped and machine tool downtime due t...

Problems solved by technology

[0003] The cutting tool wear monitoring method is divided into indirect detection method and direct detection method. The indirect detection method generally judges the current state of the cutting tool by monitoring the cutting force, vibration, acoustic emission and other sensor signals directly related to the wear amount of the cutting tool. Wear state, this method has a lot of randomness, and can only qualitatively detect the wear state of the cutting tool; the direct detection method usually refers to the detection method based on machine vision, and the direct detection method can be divided into based on the principle of structured light technology. The three-dimensional detection method based on ordinary two-dimensional camera and the vision method based on ordinary two-dimensional camera; according to the detection method, it is divided into offline detection and on-site detection. High, but the detection efficiency is low, and it is easy to cause positioning errors in the process of disassembling and assembling cutting tools
