“…Oliveira et al [56] shown that the CBN cutting tool gave better surface finish as compared to whisker-reinforced cutting tools during hard turning of the continuous and interrupted cutting. Katuku [57] suggested that the shear localization within the primary and secondary shear zones are responsible for the wear rate of the cutting tool during turning of the ASTM grade-2 austempered ductile iron (ADI) with CBN cutting tool.…”

Abstract-Turning is one of the most popular convectional machining processes to remove the extra material from the rotating surfaces. In this process, a wedge shaped cutting tool penetrated toward the workpiece and removed the extra material in the form of chips. Almost all known materials can be machined by this process in different forms like external turning, internal turning, plain/cylindrical turning, step turning, taper turning, face turning etc. with selection of appropriate cutting tool for particular material. The aim of the present study is to summarize a report on the turning process including present and past research works. This paper present a brief overview on turning operation considering the different aspects and focus the future scopes of works in the same area, which is beneficial for the researches who work in the same field.

“…Katuku et al 10 investigated the wear, cutting forces and chip characteristics of austempered ductile iron under finishing conditions. Using cutting speeds ranging from 50 m/min to 800 m/min, they observed that, at cutting speeds lower than 150 m/min, the abrasion wear was the main wear mechanism.…”

This study experimentally investigated the effects of machining parameters on the built-up-layer (BUL) and built-up-edge (BUE) formation and the wear behavior of cutting tools during the machining of the AISI 310 austenitic stainless steel with titanium-carbide cutting tools. Five different cutting speeds (50, 75, 100, 125 and 150) m/min, three feed rates (0.15, 0.20 and 0.25) mm/r and two cutting depths (1.5, 2) mm were used as the cutting parameters. The highest accumulation of the BUL and the BUE was observed at a cutting speed of 50 m/min, a feed rate of 0.15 mm/r and a cutting depth of 1.5 mm. Keywords: built-up edge, built-up layer, machining, stainless steels Ta {tudija eksperimentalno preu~uje vpliv parametrov rezanja na nakopi~eno plast (BUL) in nakopi~en rob (BUE) ter na vedenje orodja za odrezovanje med stru`enjem AISI 310 avstenitnega nerjavnega jekla z orodjem iz titanovega karbida. Kot parametri odrezovanja je bilo uporabljeno pet razli~nih hitrosti (50, 75, 100, 125 in 150) m/min, tri hitrosti podajanja (0,15, 0,20 in 0,25) mm/r in dve globini rezanja 1,5 mm in 2 mm. Najve~ja akumulacija BUL in BUE je bila opa`ena pri hitrosti rezanja 50 m/min, hitrosti podajanja 0,15 mm/r in globini rezanja 1,5 mm.

“…It is the fact well-known that the complexity of the microstructure of ausferritic ductile iron causes problems with its machining [1][2][3][4]. In its simplest description, this microstructure consists of graphite nodules and a matrix which is a mixture of the lamellae of ferrite and austenite (ausferrite).…”

In this study, a preliminary evaluation was made of the applicability ofthe signalsof the cutting forces, vibration and acoustic emission in diagnosis of the hardness and microstructure of ausferritic ductile iron and tool edge wear rate during its machining. Tests were performed on pearlitic-ferritic ductile iron and on three types of ausferritic ductile iron obtained by austempering at 400, 370 and 320⁰C for 180 minutes. Signals of the cutting forces (F), vibration (V) and acoustic emission (AE) were registered while milling each type of the cast iron with a milling cutter at different degrees of wear. Based on individual signals from all the sensors, numerous measures were determined such as e.g. the average or maximum signal value. It was found that different measures from all the sensors tested depended on the microstructure and hardness of the examined material, and on the tool condition. Knowing hardness of the material and the cutting tool edge condition, it is possible to determine the structure of the material .Simultaneous diagnosis of microstructure, hardness, and the tool condition is probably feasible, but it would require the application of a diagnostic strategy based on the integration of numerous measures, e.g. using neural networks.
