Abstract

The invention relates to an intelligent cutter of an integrated small three-way cutting force measurement system, belonging to the fields of ultraprecise cutting machining and cutting force measurement and real-time monitoring. The intelligent cutter can realize the real-time sensing measurement of small three-way cutting force in the ultraprecise machining process. The intelligent cutter mainly comprises a cutter bar, a cutting blade, a cutting force measurement system, a sealing cover and a signal interface end, wherein the upper surface of the cutting blade coincides with the central surface of the main body of the cutter bar; the cutter tip is positioned in the center of the main body of the cutter bar; the front end of the main body of the cutter bar is provided with a sensing measurement section; the small three-way cutting force measurement system is fixedly connected in a force measurement cavity of the sensing measurement section; the signal interface end is arranged at the back end of the cutter bar and is used for realizing signal output; and in the cutting machining process, a sensing unit senses the strain and displacement generated under the effect of the three-way cutting force to acquire a corresponding signal, and the small three-way cutting force is accurately computed through calibration and decoupling. The invention is used for related scientific researches in the field of ultraprecise machining and real-time monitoring and self-adaptive machining in the cutting process.

Description

technical field [0001] The invention belongs to the field of ultra-precision cutting processing and its cutting force measurement and real-time monitoring, and in particular relates to an intelligent cutting tool integrating a tiny three-way cutting force measurement system. Background technique [0002] As the most stable and reliable source of information in the machining process, the cutting force reflects the interaction between the tool and the workpiece and the surface formation process of the workpiece in its magnitude and dynamic changes. A large number of research results show that every small change in the cutting state can be reflected by the change of the cutting force, and the detection of cutting force is one of the most researched and applied monitoring methods at home and abroad. By monitoring the real-time changes in the cutting force during the machining process, through time series analysis or related data signal processing, it can be used to conduct resea...
