“…High pressure water jet assisted turning (HPWJAT) is one of the main methods used for these purposes. Studies have shown that this technique leads to better control of the chip shape [1][2][3]. With this process it is not only a question of lubricating the cutting zone, but of directing a high pressure water jet between the tool and chip to create a hydrostatic bearing.…”

“…This improves chip breakage. Different studies have been carried out to determine the effect of cutting fluids on tool wear mechanisms, chip shapes and surface roughness, obtained after machining [1][2][3][4][5]. The effects of high and ultra-high pressure water jets directed into the tool chip interface on tool temperature, cutting forces, chip shape and surface roughness in turning have been explored by Shet et al [6].…”

Abstract High pressure water jet assisted turning (HPWJAT) consists of projecting a high pressure water jet, up to several hundred bar, into the tool-workpiece interface. The water jet is directed between the chip and the tool affording greater protection of the cutting face and better chip breaking. Comparisons are made between assisted turning using several jet pressures and conventional turning with different cutting speeds on the duplex stainless steel, X2CrNiMo22-5. The results show good chip fragmentation and an improvement of tool life with high pressure water jet assistance (HPWJAT). The evolution of the roughness is also investigated. It is shown that it is possible to improve the productivity by using HPWJAT.

“…Hence, the use of a high-pressure water jet as a coolant/lubricant leads to an improvement in the metal removal rate and consequently improves the efficiency of rotary tool operations, especially in the case of difficult-to-machine materials. The effects of high and ultra-high pressure water jets directed into the tool-chip interface on tool temperature, cutting forces, [19] in regular turning operations. The results show a significant reduction in the edge temperature of about 40 745%.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. b s t r a c tThis study deals with the effect of High-Pressure Water Jet Assisted Turning (HPWJAT) of austenitic stainless steels on chip shape and residual stresses. The machining of the austenitic stainless steels represents several difficulties. Recently, research has shown that the introduction of a high-pressure water jet into the gap between the tool and the chip interface is a very satisfactory method for machining applications. In this article, the effect of a high-pressure water jet, directed into the toolchip interface, on chip shapes breakage and surface integrity in face turning operations of AISI 316L steel has been investigated. Tests have been carried out with a standard cutting tool. The cutting speeds used were 80 and 150 m/min, with a constant feed rate of 0.1 mm/rev and a constant cutting depth of 1 mm. Three jet pressures were used: 20, 50 and 80 MPa. Residual stress profiles have been analysed using the X-ray diffraction method in both longitudinal and transversal directions. The results show that jet pressure and cutting parameters influence the residual stresses and the chip shapes.
