Purpose: In this article, we present the experimental results with a dimensionless analysis of the wear behavior of a metal carbide tool in a turning operation. Design/methodology/approach: The highlighting of the dimensional input and output parameters of the experimental tests to bring out the different adimensional parameters. Regarding the input parameters, we have the rotational velocity (N), the feed (f), the depth of cut (ap), the machining time (t). The output parameters are defined by the flow rate (DC), the volume of the used tip (VU), the face wear (VB), as well as the cutting power (PC) and that of the machine (PM). Findings: The dimensionless approach allowed us to find the desired cutting conditions as well as the possibility of working in ranges of cutting conditions for known wear, which is not possible with a dimensional analysis. It should be noted that the appropriate choice of these parameters was essential to achieve these results. Research limitations/implications: The existence of a working range proposed by this analysis leads us to the proposal of a model and a numerical optimization. Practical implications: This work offers the desired compromise of adequate cutting conditions during machining. Originality/value: Deduction of adequate cutting conditions with minimum wear. Among other things, we can extrapolate the results to offer us compromises in the choice of ranges of cutting conditions.
