  • The abrasive wear characteristics of large length to diameter ratio CBN single-pass honing tools during ultrasonic dressing process were studied by single abrasive test with 4Cr13 stainless steel as dressing material. The test results show that the average cutting force during ultrasonic cutting is reduced by 60%~80% compared to that during ordinary cutting. However, the abrasives break in a short time and the grinding ratio is seriously reduced. The abrasive-workpiece contact ratio during ultrasonic cutting is mainly between 0.6 and 0.8, and the abrasives are mainly in the intermittent cutting process. Moreover, the maximum cutting width during ultrasonic cutting increase by 2.7 times compared with that during ordinary cutting, leading to an increase in the maximum cutting force on the abrasives. According to the point cloud information, the abrasive was modeled inversely, and a single abrasive cutting simulation model was established to quantitatively analyze the maximum cutting force. The simulation results show that, compared with that during ordinary cutting, the maximum cutting force during ultrasonic cutting is more than 20% higher, and the fluctuation of cutting force is more than 80%.
