Precision Engineering. Cam design has come a long way since the old days of the simple harmonic design. This design deter-mined the cam shape by using three separate radii - the nose radius, the flank radius, and the base circle radius. Today, this simple method is considered primitive because of the difficulty encountered in accurate ...
Ultrasonic vibration can be applied for grinding of difficult to cut materials, such as titanium, ceramics, etc., because the ultrasonic vibration in longitudinal direction can cause reduction of cutting temperature and tool wear. In this paper, a ultrasonic tool horn, which can vibrate longitudinally with a frequency of 20kHz, was designed using finite element method (FEM). And the ultrasonic ...
