A kind of tooth-by-tooth wear detector of front and rear cutter face of rotating tool and its detection method

Abstract

The invention relates to a tooth-by-tooth wear detector and a detection method of the front and rear cutter faces of a rotary cutter. The tooth-by-tooth wear detector of the front and rear cutter faces of the rotary tool includes: a detector, a data processing controller and a tool data server; the detector and the data processing controller are connected through a signal cable; the data processing controller is also connected with the CNC control of the numerical control machine tool The detector and the tool data server are connected; the detector is equipped with a 45-degree reflector, a telecentric lens, an inclined light source and a forward light source, and the tool image sequence is obtained during the tool rotation; the data processing controller utilizes a 45-degree The mirror turns the imaging optical path by 90 degrees. Based on the gray scale response detection principle, according to the tool image sequence, the wear images of the rake face and the flank face of the rotating tool are automatically acquired and analyzed tooth by tooth directly on the machine. By adopting the invention, the efficient and accurate direct observation of the wear image of the front and back rake surfaces of each cutter tooth can be realized under the rotating state.

Description

technical field [0001] The invention relates to the field of detection of wear of a rotary tool, in particular to a tooth-by-tooth wear detector and a detection method of a front and rear cutter faces of a rotary tool. Background technique [0002] On-machine detection of rotary tools involves five mutually independent functions, namely: tool setting, multi-view detection of micro-tools, tool runout detection, tooth-by-tooth wear detection of front and rear cutter faces, and real-time monitoring of the entire machining process. , the first four functions can only be run before and after machining, and the fifth function can monitor the tool status in the whole process of CNC machining in real time. a specific attribute. This paper only studies the independent function of tooth-by-tooth wear detection on the front and back flanks. [0003] In CNC machining, the cutting of the workpiece material by the tool will cause wear on the front and rear cutter surfaces, which will af...
