“…The authors give values 4 10 3 W=m 2 K r h int r 3:2 10 5 W=m 2 K and show that this coefficient increases with cutting speed and feed, especially when 0:1 mmr f r 0:15 mm. In numerical work of Molinari et al [38], the heat conductance was chosen 2 10 3 W=m 2 K r h int r 10 9 W=m 2 K: and in List et al [39], the value of 10 6 W=m 2 K was used to ensure a rapid stabilization of the cutting temperature at the TCI. Therefore, in this work, the thermal conductance h int at the TCI is chosen equal to 10 3 W=m 2 K for feed f r0:3 mm and 10 6 W=m 2 K for f ¼ 0:5 mm.…”

“…Their results showed that the increase in cutting speed from 10 to 65 m/s maximizes temperature at the chip continuously. List, Sutter, and Bouthiche (2012) predicted the interface cutting temperature and its relation with the crater wear mechanism. Their work was focused on the domain of the high-speed machining above 20 m/s.…”

Hard turning is a recent technology that involves machining of hard steels using modern machine tools. Hard machining presents challenges in terms of selection of tool insert with improved tool life and high-precision machining. Turning of hardened steels using single-point cutting tool has got considerable interest among manufacturers of ball bearings, automotive, gear, and die industry. Hard turning in the automotive industry and bearing applications typically has a number of potential benefits over traditional form grinding including lower equipment costs, shorter setup time, and fewer process steps which in turn provides high flexibility and ability to cut complex geometries. Moreover, the hard turning process is usually carried out without coolant/lubricant and thus, the problem of storage, handling, and disposal of cutting fluid is eliminated, and at the same time, it probably favors the health of operators. This paper presents an overview of the past research hard turning using hard turning tools such as PCBN, cubic boron nitride, Ceramics, Carbide, etc. Major hard turning cutting materials and effect of hard turning process parameters on cutting forces, heat generation during cutting, surface finish and surface integrity, and tool wear have been discussed in light of the findings of the past research.

Abstract:The degree of holding temperature and time play a major role in nano-case treatment of cutting tools which immensely contributed to its performance during machining operation. The objective of this research work is to carryout comparative study of performance of nano-case treatment tools developed using low and medium carbon steel as work piece. Turning operation was carried out under two different categories with specific work piece on universal lathe machine using HSS cutting tools 100 mm x 12mm x 12mm that has been nano-case treated under varying conditions of temperatures and timeof 800,850, 900, 950 o C and 60, 90, 120 mins respectively. The turning parameters used in evaluating this experiment were cutting speed of 270, 380 and 560mm/min, feed rate of 0.15, 0.20 and 0.25 mm/min, depth of cut of 2mm, work piece diameter of 25mm and rake angle of 7 o each at three levels. The results of comparative study of their performances revealed that the timespent in the machining of low carbon steel material at a minimum temperature and time of800°C, 60 mins were1.50, 2.17 mins while at maximum temperature and time of 950°C , 120 mins were 1.19, 2.02 mins. It was also observed that at a corresponding constant speed of 270,380 and 560mm/min at higher temperature and time, a relative increased in the length of cut were observed.Critical observation of the result showed that at higher case hardening temperature and time (950°C/120mins), the HSS cutting tool gave a better performance as lesser time was consumed during the turning operation.
