AbstractThe quantification of friction coefficient along the tool-workmaterial interface in machining remains an issue in tribology. This paper aims identifying the evolution of friction coefficient for a large range of sliding velocity during the machining of a AISI4140 steel (290 HB) with a TiN coated carbide tool. The influence of a straight oil is investigated compared to a dry sliding situation (dry machining). It has been shown that, in dry machining, friction coefficient decreases with the sliding velocity until reaching a downer limit around 0.2. On the contrary, the presence of a straight oil decreases significantly friction coefficients to a value around 0.1. Additionally, the friction coefficient becomes independent from the sliding velocity. It also been shown that a straight oil is able to penetrate the pin-workmaterial interface even if a very high contact pressure is present (~3 GPa). The penetration duration is very fast, whereas its evacuation duration is much higher and strongly dependant on sliding speeds.

“…Various metal-cutting operations such as turning, drilling, boring, reaming, tapping, cylindrical grinding and surface grinding have been considered in the past to evaluate the cutting fluids. It is observed from the literature survey [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] that the existing procedures of cutting fluid selection for any given machining application are mainly identifying a cutting fluid matching with the tool, work material and machining operation.

This paper presents a methodology to select a cutting fluid for a given machining application using the digraph and matrix method. A cutting fluid index is proposed which evaluates and ranks cutting fluids for a given machining application. The index is obtained from the cutting fluid function, obtained from the cutting fluid attributes digraph. The digraph is developed considering cutting fluid attributes and their relative importance for the considered operation. Coefficients of similarity and dissimilarity and the identification sets are also proposed. These are obtained from the cutting fluid function and are useful for easy storage and retrieval of the cutting fluid data. An example is included to illustrate the approach.

“…From an operation point of view, requirement on lubricating efficiency of cutting fluid is pronounced for reaming operation due to low speeds and feed rates generally utilised, allowing built-up edge (BUE) occurrence. From a test point of view, reaming test provides easier surface quality evaluation compared to e.g., tapping, previously proposed as standardised test procedure by Lorenz (1985).…”

Abstract:The reproducibility of a reaming test was analysed to document its applicability as a performance test for cutting fluids. Reaming tests were carried out on a drilling machine using HSS reamers. Workpiece material was an austenitic stainless steel, machined using 4.75 m·min -1 cutting speed and 0.3 mm·rev -1 feed. A mineral straight oil and a water-based lubricant at two different oil concentrations were compared with respect to hole quality, evaluated in terms of surface finish (conventional arithmetic mean roughness Ra and roughness profiles), and hole geometry (hole diameter and roundness). Process reproducibility was assessed as the ability of different operators to ensure a consistent rating of individual lubricants. Absolute average values as well as experimental standard deviations of the evaluation parameters were calculated, and uncertainty budgeting was performed. Results document a built-up edge occurrence hindering a robust evaluation of cutting fluid performance, if the data evaluation is based on surface finish only. Measurements of hole geometry provide documentation to recognise systematic error distorting the performance test.[ He is an internationally recognised expert in manufacturing and metrology, having published over 200 technical papers in international journals and conference proceedings. His theoretical models quantifying the role of friction and lubrication in metal cutting are described in textbooks worldwide.
