摘要

In order to study the cutting force of the SiCp/Al composite material assisted by quasi-intermittent vibration swing cutting, the cutting force was decomposed into cutting direction, feed direction, and cutting depth direction, and the special frictional force and special periodic swing plow force generated by swing were analyzed in detail. The cutting force of SiC particles is also determined by three-body rolling and two-body sliding friction. The orthogonal experiment with four factors and three levels was designed and used to verify the accuracy of the cutting force prediction model by changing the cutting depth, cutting speed, feed rate, and frequency. Finally, the effect of cutting depth, frequency, and phase on cutting force is analyzed by single factor experiment. The results indicate that the error of cutting force in all three directions is less than 11%. With the increase of frequency and phase, the average cutting force decreases, and the processing effect is best when the phase difference is π/2.
