Method for constructing diamond milling and grinding head state monitoring system for machining ceramic mobile phone backboard

Abstract

The invention provides a method for constructing a diamond milling and grinding head state monitoring system for a machining ceramic mobile phone backboard. The method is characterized in that the diamond milling and grinding head wear state monitoring system comprises a machining platform, a milling and grinding head wear signal collection module, a wear process signal processing and feature extraction module, an intelligent decision-making module and a man-machine interaction module for online real-time feedback of milling and grinding head wear conditions. By applying the technical scheme,the requirement of an actual mobile phone ceramic backboard enterprise processing plant for monitoring the tool wear state in engineering application can be met.

Description

technical field [0001] The invention relates to the field of on-line monitoring of tool wear of CNC machine tools, in particular to a method for building a state monitoring system for a diamond milling head for processing ceramic mobile phone back plates. Background technique [0002] With the coming of the 5G era, smartphone backplane materials are being updated, and non-electromagnetic shielding materials have been reused, while ceramic materials stand out in the new round of technology reshuffle. Due to their high hardness, ceramics can pass the drop test (1.2 meters high), The texture and color effect are better, and it has become a new type of mobile phone body material after plastic, metal and glass, and is favored by mobile phone manufacturers. [0003] However, due to the high hardness, brittleness and high wear resistance of ceramic materials, diamond tools wear quickly and have a short service life. Therefore, the quality of the tool for processing ceramic backplan...

Problems solved by technology

[0003] However, due to the high hardness, brittleness and high wear resistance of ceramic materials, diamond tools wear out quickly and have a short service life. Therefore, the quality of the tool for processing ceramic backplanes will directly affect the quality of the processed workpiece.

At this stage, for the monitoring of the wear state of the diamond milling head tool during the processing of the zirconia ceramic backplane, it mainly relies on the experience of the workers, the guiding opinions of the tool manufacturer, and the relevant process standards formulated by the process department. Two problems: The first problem is that the accuracy of workers' judgment is limited, which will cause the waste of tools and unqualified parts, which will affect the economy of production; the second problem is that direct observation of tools requires frequent stoppage of processing, which affects production Efficiency has a huge impact
