“…It was highlighted that coated cutting tools were resistant to abrasion and that a better quality of hole was obtained with them. Previous studies reported that increasing the cutting speed in operations using coated drills led to a decline in the cutting forces and torque [6][7][8][9][10]. They emphasized that mathematical models had been developed using the results of various experimental data analyses, and that most of the analysis results of these models had proven to be compatible [11][12][13][14].…”

SummaryIn this study, drillability experiments were carried out on the AISI H13 hot work steel which is difficult to machine. Uncoated and AlCrN-coated carbide drills, ø14 mm, were used at 4 cutting speeds (60, 75, 90 and 108 m/min) and three different feed rates (0.15, 0.20 and 0.25 mm/rev). As a result of the experimental work, it was observed that an increase in the feed rate caused an increased on the thrust force in the workpiece machined with both the uncoated and coated drills. While an increase in the cutting speed caused the thrust force to increase in operations performed with uncoated drills, the increased cutting speed led to a decreased torque. In contrast, an increase in the cutting speed caused both the thrust force and the torque to decrease in the operations with coated drills. Stresses occurring on the drills were analyzed and a mathematical model was developed using the finite element method and the ANSYS Workbench package software.

“…[3] In the previous years, many studies have been carried out to explore different facets of the hard turning of alloy steel. Ramesh et al [4]examined the differences in structure and properties of white layers formed during machining of hardened AISI 52100 steel (62 HRC) at different cutting speeds. Their results indicated that the grain sizes of white layers formed were considerably smaller than the grain sizes of the bulk.…”

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.
