Abstract

The invention relates to a vision-based tool monitor and a tool monitoring method thereof. The vision-based tool monitor comprises a detector, a data processing controller and a tool data server, wherein the detector is connected with the data processing controller through a signal cable, a clean air pipe, a plunger air pipe and a positive pressure protection air pipe; the data processing controller is also connected with a computer numerical controller (CNC) and the tool data server separately; and a telecentric lens and a light source backboard are arranged in the detector and used for carrying out parallel projection imaging on a tool, a tool image sequence is formed, the tool image sequence is analyzed by the data processing controller, and the tool length and tool diameter are calculated and transmitted to the CNC. By adopting the vision-based tool monitor, the tool monitoring efficiency and accuracy can be improved, the traceability of historical measurement data is supported, and thus the precision of numerical control machining is guaranteed, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the field of on-machine detection instruments for numerical control machining, in particular to a visual on-machine tool setting instrument and a tool setting method thereof. 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 article only studies the independent function of knife setting. [0003] In order to ensure the accuracy of CNC machining, tool setting must be performed before cutting with rotary tools, that is, to detect the clamping length of the tool on the sp...
