Resumo | Silicon nitride ceramics are promising candidates for engineering and tooling applications because of the excellent combination of their intrinsic mechanical, thermal and chemical properties [1]. However, these cutting tools with diamond coating do not present information as cutting material in dry turning operations of compacted graphite iron. In the present work, silicon nitride square inserts was developed, characterized and diamond-coated to be apply on dry machining process of compacted graphite iron (Fig. 1a and 1b). Compacted graphite iron (CGI) it is not used in a larger extension of production because its machinability, which is very difficult as compared to others automotive industry materials [2]. Dry machining studies have been conducted using the new developed cutting tool insert on compacted graphite iron (CGI) at cutting speed of Vc1=300, Vc2=400 and Vc3=500 m/min with a feed rate of 0.20 mm/rev and a depth of cut of 0.5 mm. In the Fig.1c can be observed the wear process taking place on the rake and flank faces of the ceramic inserts, in all cutting conditions. The increase in cutting speed resulted in higher cutting temperature and shorter tool life time. This is due to the carbon graphitization promoted by the increase in temperature during the cutting process. The graphitization process provokes the removal of the diamond coating. The flank wear (VB) was measured by optical microscopy in all cutting inserts and the values are shown in Fig.1d. In general, the flank wear revealed that the tool life of diamond-coated inserts is longer than uncoated inserts [1]. The dominant wear mechanism is abrasion caused by loose diamond debris from the sliding action of the chip and workpiece rubbing on the rake and flank faces, respectively. |
