Effects of axial ultrasonic vibration on grinding quality in peripheral grinding and end grinding of ULE

摘要: Axial ultrasonic vibration–assisted grinding has been widely proved to be effective on the ground quality as well efficiency for hard and brittle materials. However, deference of two typical modes, axial peripheral (AUPG, vibration directions are parallel surface) end (AUEG, vertical surface), exerting process not yet thoroughly investigated. In this paper, single grain kinematic functions corresponding AUPG AUEG have created theoretically analyze interactional mechanism respectively. For AUEG, their vibrations capable increasing dynamic contact length, decreasing chip thickness, but different effects behavior need further investigation. A series comparative experiments conducted subsequently, results show that under identical material removal rate, in can decrease forces, while is with a lower one than factor 39.80%. With regard surface subsurface damage, shows positive effect negative role. The kinematic, force, quality, damage analyzed terms experimentally, conclusion will meaningful researchers choose appropriate approach applying optical elements.
