Problems solved by technology

Specifically, direct measurement mainly includes: resistance measurement method, tool workpiece distance measurement method, ray measurement method, microstructure coating method, optical measurement method, discharge current measurement method, computer image processing method, etc.; but these methods often require detection Harsh conditions or complicated preparations lead to a narrow range of practical applications
Indirect measurements include: cutting force detection method, acoustic emission detection method, power signal detection method, vibration signal detection method, cutting temperature measurement method, current signal measurement method, thermal voltage measurement method, workpiece surface roughness measurement method, etc.; but due to indirect There are many indirect influencing factors during measurement, and it is difficult to obtain features directly related to the appearance of the milling cutter, resulting in low detection accuracy

Abstract

The invention belongs to the related field of CNC machining tool detection, and discloses a method, device and application for detecting damage of a milling cutter based on a permanent magnetic disturbance probe. Then, the milling cutter to be tested is rotated at the preset speed to make the permanent magnetic disturbance probe generate a signal, and then the signal of the permanent magnetic disturbance probe is collected, and the collected signal is processed to judge whether the milling cutter to be tested is breakage occurs. The milling cutter breakage detection method and device of the present invention can be applied to the milling processing method and system to realize the milling cutter breakage detection during the milling processing, and has the advantages of accurate detection, easy manipulation, and wide applicability.

Description

technical field [0001] The invention belongs to the related field of CNC machining tool detection, and more specifically relates to a milling cutter damage detection method, device and application based on a permanent magnet disturbance probe. Background technique [0002] With the continuous improvement of the degree of automation and intelligence in the manufacturing industry, in the process of CNC machining, the requirements for the monitoring technology of the cutting process are also getting higher and higher. Especially in the process of intermittent milling, the breakage of the milling cutter often occurs, which may lead to the scrapping of parts, and may cause damage to the machine tool, so it is necessary to detect the breakage of the milling cutter. [0003] At present, there are two types of detection for milling cutters: direct measurement and indirect measurement. Specifically, direct measurement mainly includes: resistance measurement method, tool-workpiece di...
