THE USE OF CUTTING FORCE AND ACOUSTIC-EMISSION SIGNALS FOR THE MONITORING OF TOOL INSERT GEOMETRY DURING ROUGH FACE MILLING

The use of acoustic emission (AE) and cutting force has been applied t o the detection of changes in milling tool insert geometries. These ge ometries, produced by precision grinding, were intended to simulate di fferent forms of naturally occurring wear such as crater, notch and fl ank wear, local changes in rake angle and edge breakdown. The results indicate that both cutting force and AE can be used as indicators of c hanges in cutting tool geometry with consequent implications for diagn ostic, geometry-specific, wear detection.
