“…Turning of hardened metals (hard turning), has been popular in recent years as an economic way of generating a high quality finish on steels with a hardness of 60-65 Rc (1)- (4). Compared with grinding, hard turning can machine complex workpieces in one step.…”

Tool wear and machining performance of hardened AISI M2 steel in hard turning has been studied. Ceramic tools were used in the cutting tests without coolants, and the workpiece was heat treated to increase its hardness up to Rc 60. Cutting forces, temperature, and tool wear were measured in the experiments and the effects of cutting conditions on these were investigated. Important aspects from the research are summarized as follows:I . Flank wear was the dominant wear mode on the ceramic tool insert in hard turning. In contrast, crater wear was very small due to the ceramic's high resistance against chemical reactions at high temperature. A notch was unlikely to be formed in the tool.2. The initial flank wear rate mainly depends on the feed rate. High feed rates cause a high initial flank wear rate.3. Depth of cut was the most important cutting parameter to affect cutting force variation, and the cutting force increased due to tool wear.

“…The established method was applicable to estimate on-line the roughness of cylindrically ground surface with reasonable accuracy and to estimate the roughness of other ground and turned surfaces. Diniz et al (1992) conducted related experiments to monitor the change of surface roughness caused by the deterioration of tool wear, through the variation of acoustic emission in finish turning, under different cutting conditions. The signal-processing analysis was done on the AE rms signal filtered using a high bandpass and on the AE rms filtered using a smaller bandpass.…”

“…Once acoustic emission signatures, thresholds and bandwidth are established for a specific process configuration, the AE signal and AE RMS may be monitored and compared to nominal values to detect abnormal events such as tool breakage [15] or unacceptable tool wear [8,16,17]. However, few if any surface integrity parameters including residual stress, microstructure changes [13], and surface finish [18] were on-line monitored, except a brief discussion by Toenshoff [3].…”
