Device for intelligently detecting abrasion of numerical control cutting tool

Abstract

The invention belongs to a device for detecting the abrasion of a machining cutting tool, and in particular relates to a device for intelligently detecting the abrasion of a numerical control cutting tool. In the device, a sensor signal processing circuit is used for detecting a cutting temperature and a cutting vibration value of the cutting tool in the machining process on line; a liquid crystal display circuit is used for displaying measured parameter values and dynamic curves of the measured parameter values along time variation; a singlechip control circuit is used for determining the abrasion rate according to the curves, predetermining the abrasion of the cutting tool and performing analysis processing on the abrasion; and when a measured temperature value and any value in vibration quantity are greater than a critical value, an alarming circuit is used for automatically giving an alarm. By the device, the cutting temperature and the cutting vibration value of the numerical control cutting tool can be detected and the abrasion of the numerical control cutting tool can be alarmed without the dependence on the sensation and the manual estimation of detection personnel, so that the cutting tool and a machine tool exert the highest machining capability and are effectively protected, the service life of the cutting tool is prolonged, and the machining quality of the cutting tool is improved; and the device has low cost and a simple circuit structure, is convenient to control and stably operated, can be applied to different machining operating conditions and improves the compatibility and the adaptability of a system.

Description

Technical field [0001] The invention belongs to a tool wear detection device for machining machining, in particular, it performs online automatic monitoring through changes in physical quantities during the cutting process of the tool. Background technique [0002] In the automated or semi-automated machining technologies such as CNC machine tools and flexible machining systems, cutting tools are the most direct factor that affects the quality of parts processing and production efficiency. In view of the non-real-time nature and limitation of the scope of application in the current existing tool wear detection devices, it is impossible to accurately control the actual wear of the tool in the cutting process in time, therefore, it affects the quality of product processing and the automation of the processing process. The level needs to be improved and further improved. Summary of the invention [0003] The invention accurately controls the actual wear of the tool in the cutting pr...
