Study of the performances of nano-case treatment cutting tools on carbon steel work material during turning operation

Abstract

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.

Dataset on experimental investigation of optimum carburizing temperature and holding time of bi- nano additives treatment of AISI 5130 steel

“…Weight loss and wear volume of each sample was investigated using Rotopol-V during machining as recorded in Table 3. The test for core, interface and surface hardness of the samples were done using hardness tester shown in Table 4 [18], [19]. The values for the wear rate and average hardness of each sample were carried out and all were indicated in Table 5 [20].…”

“…These types of materials have developed as appropriate alternatives to by-pass restrictions of micro composites and monolithic, they are stated to the 21 st century materials in the view of retaining design distinctiveness and combinations of property that are not established in conventional composites [5]. According to Afolalu et al [6], today nanocomposites are currently being used in numerous fields. This is because they can radically improve the properties of the weld by enhancing the mechanical properties of the weld with strength, modulus, and dimensional stability inclusive.…”
