“…4, is very low with the application of LN, falling in the contour region of 0-50 °C, as compared to the dry cutting condition that generated a very high temperature in the contour region of 500-600 °C at the tip of the insert. Consequently, a larger "hot spot" area was developed on the tool edge up to the tool rake face in the dry cutting, making the edge became a heat sink and overheat [18]. This will be a contributing factor to crater wear progression.…”

“…This results in a steeper temperature gradient across the chip and varies the degree of material contraction on the upper side and the underside of the debris due to the different temperature values. Consequently, tighter chip curl and shorter chip-tool contact length are produced in the cryogenic turning [18]. A shorter contact length is favourable due to several reasons.…”

“…A shorter contact length is favourable due to several reasons. It is claimed to be able to reduce the tool wear, especially crater wear [18], besides assisting the entrainment of the LN into the primary deformation zone and act as a coolant and lubricant more effectively. The reduction in contact length between chip-tool interfaces in the cryogenic turning is also proven in the simulation, as shown in Fig.…”

A localized high temperature area occurring at the tip of the tool during a cutting process can be detrimental and lead to a rapid wear mechanism. This paper presents the effect of a cryogenic application during the machining process on the temperature generated at the tool-chip interface, compared to a dry environment in the turning of the AISI 4340 alloy steel using a coated carbide tool. The cutting temperature was estimated using the Third Wave AdvantEdge software, which then was validated with the turning experiments. A significant reduction of the cutting temperature and the steeper temperature gradients on the cutting edge and the chips were observed in the cryogenic machining, which indicates more effective heat removal from the cutting zone. The sudden cold of -196 °C caused the chips to become hard and brittle, which enhanced the chip breakability during the machining process.

In this study, experimental optimization of cutting forces, surface roughness and the hardness of material after turning of AISI 316L stainless steel, using conventional and wiper insert cutting tools under dry, CO2 and MQL cutting conditions, is presented. The influences of feed rate, cutting depth, and cooling system on surface roughness, cutting force and material hardness were examined. In order to optimize the turning process, Grey relational analysis optimization method was used. The optimal machinability parameters of AISI 316L stainless steel with coated carbide insert were successfully determined.

ResumenEl objetivo de este trabajo es el estudio experimental de la evolución del desgaste del flanco respecto al tiempo de dos insertos de carburo recubiertos y un cermet durante el torneado de acabado en seco del acero AISI 1045 con velocidades de corte de 400, 500 y 600 m/min. Los resultados fueron comparados utilizando el análisis de varianza y el análisis de regresión lineal para describir la relación entre el desgaste del flanco y el tiempo de maquinado, obteniéndose la ecuación del modelo ajustado. La investigación demostró un efecto significativo de la velocidad de corte y del tiempo de maquinado en el desgaste del flanco en el maquinado de alta velocidad. El mejor desempeño se obtuvo para el carburo recubierto con tres capas, mientras que el carburo con dos capas sufrió el mayor desgaste a elevadas velocidades de corte.

Flank wear study of coating carbides and cermet inserts during the dry high speed turning of AISI 1045 steel AbstractThis work deals with the experimental study of the flank wear evolution of two coating carbide inserts and a cermet insert during the dry finishing turning of AISI 1045 steel with 400, 500 and 600 m/min cutting speeds. The results were analyzed using the variance analysis and lineal regression analysis in order to describe the relationship between the flank wear and machining time, obtaining the adjusted model equation. The investigation demonstrated a significant effect of cutting speed and machining time on the flank wear at high speed machining. The three coating layers insert showed the best performance while the two layers insert had the worst behaviour of the cutting tool wear at high cutting speeds.
