It determines the rounding radius when machining concave shapes as V grooves. Ultrasonic vibrations have been applied to grinding in order to reduce the grinding force. This has led to the production of pins in cemented carbides of 11 µm in diameter and 160 µm in length as well as micro flat drills of 17 µm in diameter and 100 µm in length.
