“…It is known that the change in this value corresponds well with tool wear, especially under finishing machining conditions where the depth of cut is small. ( (Murata et al, 2012;Murata et al, 2013;Gouarir et al, 2016) We have also found a good relationship between the change in the output signal of the slip rate of AC spindle motor and the progress of tool wear. (Murata et al, 2021) Acquisition of signals that correspond very well to the progression of tool flank wear does not require a particularly expensive measuring instrument.…”

Holm's contacts theory is a theory experimentally obtained for the contact electrical resistance value of metalto-metal contacts. It has been reported that the value of this contact electrical resistance changes with the area of the contact surface if the contact pressure does not change. On the other hand, in cutting, as the flank wear of the tool progresses, the contact area between the tool and the work material increases. The authors have focused on the increase in the contact area between the tool and the work material due to the progress of tool wear and devised an in-process measurement method for the contact electrical resistance between the tool and the work material in intermittent cutting process. And it was found that there is a good relationship between the progress of tool flank wear and the change in contact electrical resistance between the tool and the work material. In this study, Holm's contact theory was used as a method to identify the flank wear width from the change in the contact electrical resistance value. Considering combinations of cutting tool materials, with or without of coating, use of cutting fluid, and work material grades, etc., the number of conditions to be verified is extremely large. As a result, although the cutting conditions were very limited, however good identification results were obtained in areas where the depth of cut was small.

“…It is known that the state of a cutting edge can be appreciated by the value of cutting electrical current voltage [2][3][4][5][6][7][8]. The higher this value is, the higher the initial temperature is [9,10], due to the imperfections of the cutting edge.…”

Abstract. At metal drilling, at the beginning of the process, the cutting tool in the chisel edge zone, frictions and plastically deforms the material, and then enters in cutting. If the drill is entered smoothly in cutting with a special device, its life is increased. The paper presents how the electrical current at cutting is used for the evaluation of smooth entrance in cutting in comparison with classical cutting. These are demonstrated for 41MoC11 steel drilled with a set of 30 tools having 8 mm diameter.

Abstract. During the process of drilling metals there are used cutting tools that can be acquisitioned directly from the producers, from distributors or from supermarkets. Because the offer is varied and there are different producers, the acquisition must be made after an economical analysis that includes experimental tests. The paper presents an innovative methodology of drills acquisition based on electrical current at cutting process. The researches were developed using HS 6-5-2 steel drills of 8 mm diameter, in two batches, acquisitioned from two different suppliers, at different prices. The drills were tested on 1C45 material using the same values for cutting parameters and because the electrical current at cutting is sensible to any imperfection of the tools, the batches were analysed from qualitative and economical point of view.
