It is worth noting that the cutting forces of the z-axis with ultrasonic vibration are not always less than conventional milling. This is main-
In recent years, there has been a challenge: how to meet the requirements of cutting lubrication and use the least cutting fluid for environmental protection simultaneously. To resolve this problem, novel cutting tools with micro textures on the rake face for lubrication were proposed, which can directly transport the cutting fluid to the tool-chip contact interface by …

In machining processes, tool performance is measured by the tool life, which is determined by the tool wear rate. This rate is strongly dependent on the tool wear mechanisms that occur in a specific process. Moreover, determining the wear mechanism is a fundamental task for the development of cutting tools. However, the tool wear mechanism depends on …
