Design of Mechanical Stirring Device with Ultrasonic-Alternating Electric Field Coupling Cycloidal Motion

Abstract

In an effort to overcome the problem of ineffective cutting or broaching caused by the agglomeration phenomenon during the production of green nano-cutting fluids, a novel agitator was developed. This design employs the mathematical mechanism of ultrasonic-alternating electric field coupling cycloid motion to prepare a green nano-cutting fluid with improved dispersion uniformity. The non-uniform alternating electric field generated by the arc electrode is used to establish a coupled physical field with the ultrasonic field. Meanwhile, the motor-driven ultrasonic stirring rod’s cycloid motion stirring, in conjunction with the temperature control system, is utilized to facilitate the preparation of the cutting fluid. After that, the cutting fluid is used for broaching tests. The comparative analysis of the test results demonstrated that the utilization of the stirrer in the preparation of green nano-cutting fluid yields a significant reduction in broaching load during the broaching test, as compared to cutting fluids prepared using alternative methods.
