Figure 19. Ma<strong>in</strong> and <strong>in</strong>teraction effects on edge chipp<strong>in</strong>g size <strong>in</strong> RUM of CMC (after [Li et al., 2006]).<br />

The <strong>in</strong>teraction between feedrate and ultrasonic power is also significant. With the<br />

<strong>in</strong>crease of feedrate, the chipp<strong>in</strong>g size will <strong>in</strong>crease at the higher level of ultrasonic power<br />

while decrease at the lower level of ultrasonic power as shown <strong>in</strong> Figure 19(c).<br />
