Three types of alumina-based ceramic tools SN60, AZ5000 (zirconia toughened), A65, HC2 (titanium carbide reinforced) and CC670 (silicon carbide whisker reinforced) were used for the evaluation of cutting performance when machining a high tensile steel (AISI 4340). Experimental studies were carried out at various cutting speeds (200--600 m/min), feeds (0.1--0.4 mm/rev) and depths of cut (0.5--2.0 mm), in dry conditions. The cutting performance of alumina-based ceramic tools was judged according to the cutting force produced during the process of machining, surface roughness of the workpiece and wear rate of the cutting inserts. A piezoelectric dynamometer was employed to measure the cutting forces. The flank wear was used to determine the tool-life of these inserts. The cutting performance of these alumina-based ceramic tools was analyzed and compared. The influence of cutting parameters (i. e. cutting speed, feed rate and depth of cut) on cutting performance is discussed.
