Design and Application of Magnetic Field-assisted Cutting Device for Micro-weaving Tools
The application of magnetic field assisted tool cutting machining technology to the cutting performance of micro-woven tools is investigated.Based on ANSYS design and finite element simulation of the cutting machining fixture,the magnetic field generation device is designed and the magnetic field assisted cutting platform is built according to the Biot-Savard law,and the influence of the choice of magnetic field parameters on the cutting performance is investigated.In this paper,cutting tests are carried out on 316L stainless steel using a micro-weave tool(TT)and magnetic nanofluids(MNF)with a certain magnetic field strength varying the magnetic field direction(DIR1 for micro-weave parallel to the magnetic field direction,DIR2 for micro-weave perpendicular to the magnetic field direction and DIR3 for chip direction parallel to the magnetic field direction),and the machined workpiece is characterised and analysed by SEM and EDS.The results show that the optimal cutting performance is achieved with the microweave tool at a magnetic field direction of DIR1.It's demon-strated that the choice of magnetic field parameters has an important influence on the cutting performance of the microweave tool and provides guidance for the practical application of magnetic field assisted cutting technology.
