“…Machining of CGI has been studied in all traditional machining methods, such as turning, milling, and drilling [4][5][6][7][8][9]. Rose et al [8] studied the effect of the content of Ti on tool wear and surface roughness in CGI turning. The results indicated that the increasing content of Ti in CGI could dramatically decrease the tool life.…”

Compacted graphite iron (CGI), which is used as a potential material in the auto industry, is a hard-to-machine material for the different minor elements and for the geometry of graphite with grey cast iron. The machinability of CGI in the drilling process was investigated with a 4-mm diameter fine-grain carbide twist drill under four lubrication conditions, dry (no compressed air), dry (with compressed air), MQL 5 ml/h, and MQL 20 mL/h in this paper. The maximum flank wear, types of wear, and cutting loads were studied for identifying the wear mechanism in drilling of CGI. The tool life in the four experiments of CGI drilling is 639 holes, 2969 holes, 2948 holes, and 2685 holes, respectively. The results showed that the main wear mechanism in drilling of CGI is adhesion and abrasion. Carbon, which originates from the graphite of CGI, can improve the lubrication in the drilling process by comparing with MnS in drilling grey cast iron. The thrust force and torque are more than 1000 N and 150 N*cm after 2700 holes in CGI drilling. Drilling of CGI under dry conditions (with compressed air) and MQL 5 ml/h is feasible.

“…Commonly, poor surface quality is directly linked to vibration in machine tools or due to run out or great overhang of the tooling. However, the response issued by vibration sensors appears just when occurring high levels of tool wear due to the abrupt variations in the process [3,4].…”

The great challenge of modern industry is to carry out an online prediction in the shop floor during the machining to define the exact tool breakage instant and simultaneously improve the quality of manufactured products. Acoustic emission sensors have been used to monitoring traditional and non-traditional machining processes. This work shows a study of the online monitoring in the microturning process using an acoustic emission sensor. A factorial design was performed to examine the effect of the feed rate, depth of cut, cooling system, and the type of tool on the response acoustic emission signal. Moreover, the acoustic emission signal was correlated with surface roughness and microhardness. The results showed that the acoustic emission signals are sensitive with the progressive increase in surface roughness and the microhardness.

“…Em virtude da inerente complexidade dos processos de usinagem é virtualmente impossível predizer a usinabilidade de um sistema (SHAW, 1984). As propriedades mecânicas superiores do CGI em relação ao alumínio e ao ferro fundido cinzento tornam a usinagem deste material um desafio, sendo esta menor usinabilidade evidenciada nos processos de torneamento (SKVARENINA; SHIN, 2006;ROSA et al, 2010;NAYYAR et al, 2012;NAYYAR et al, 2013;STALBAUM, 2013), furação (MOCELLIN et al, 2004; EVANS; HOOGENDOORN; PLATT, 2013) e fresamento (DAWSON et al, 2001;ABELE;SAHM;SCHULZ, 2002;NAVES, 2009…”
