Rotary cutter front-back cutter face tooth-by-tooth wear detector and detection method

Abstract

The invention relates to a rotary cutter front-back cutter face tooth-by-tooth wear detector and detection method. The rotary cutter front-back cutter face tooth-by-tooth wear detector comprises a detector body, a data processing controller and a cutter data server, wherein the detector body and the data processing controller are connected by means of a signal cable, the data processing controlleris further connected to a CNC controller of a numerical control machine tool and the cutter data server, a 45-degree reflector, a telecentric lens, an inclined light source and a forward light sourceare arranged in the detector, a cutter image sequence is obtained in the rotation process of a cutter, the data processing controller performs 90-degree steering on an imaging optical path by using the 45-degree reflector, based on a gray-scale response detection principle, wear images of a front cutter face and a rear cutter face of the rotary cutter are directly acquired and analyzed directly in an on-machine mode tooth by tooth according to the cutter image sequence. The detector can be adopted to realize efficient and accurate direct observation of wear images of the front and rear cutterfaces of all cutter teeth in the rotating state.

Description

Technical field [0001] The invention relates to the field of rotating tool wear detection, in particular to a tooth-by-tooth wear detector for the front and rear face of a rotating tool and a detection method thereof. Background technique [0002] On-machine inspection of rotary tools involves five mutually independent functions, which are: tool setting, multi-view detection of micro-tools, tool runout detection, tooth-by-tooth wear detection of front and rear tool faces, and real-time monitoring of the entire machining process. , The first four functions can only be run before and after processing, while the fifth function can monitor the tool status in the whole process of CNC machining. These five functions are independent of each other and focus on certain aspects of the tool status. A specific attribute. This article only studies the independent function of tooth-by-tooth wear detection on the front and rear face. [0003] In CNC machining, the cutting of the workpiece mater...
