Conventional Face Die-Sinking

The machining process is generally designed by first selecting the mean grain size considering the desired removal rate and the resulting surface

If the feed motion of a shape-generating counterpart in axial direction is parallel to the ultrasonic vibration, the process is called conventional face die-sinking. The process can be used purely for drilling or for the generation of profiles in the workpiece. In this case, a profiled shape-generating counterpart is used, whose negative shape is projected onto the workpiece (Figure 17.4a).
