“…As the cutting tool processes in difficult conditions, the quality of the drill must be as homogeneous as possible. Research [6] shows an innovative method of assessing the quality of drills using the electrical current at cutting. At the same time, any research aimed at increasing the durability of the drill is welcome.…”

Metal drilling is one of the most common methods of obtaining cylindrical bores. At the same time, the drill is the cutting tool that cuts in the most difficult conditions and consequently any measure that leads to the improvement of the cutting process is useful. The smooth entrance in the cutting is a way to increase the durability of the drill and consequently specific devices have been developed. One of these devices is shown in this paper and previous research shows the effectiveness of its use in drilling. The analysis of the device shows that it is used for cutting 41MoC11 and C45 steels with high speed steel drills, which are in a small range of sizes. The active element of the device is identified, a helical spring working for compression, and by calculating the respective axial force of the torque, is determined exactly the range of diameters of the drills that can cut effectively. At the same time is analyzed the way of enlarging the range of drills used with the device for smooth entrance in cutting, by introducing a second spring, concentric with the first, and which works simultaneously with it, thus the device was reengineered.

Abstract. During the process of turning metals there are used cutting inserts that can be acquisitioned from different producers. Because the offer is varied the acquisition must be made after an economical analysis that includes experimental tries. The paper presents an acquisition methodology for metallic carbide cutting inserts and presents a case study. This research was developed using three batches of cutting inserts acquisitioned from different producers. The specimen material was 1C45 and using the electrical current at cutting, the batches were analysed from qualitative and economical point of view.

The optimization of the turning cutting parameters was a permanent concern for research but also for production. The emergence of new metal materials to be processed as well as the development of new cutting edges has always led to new optimizations of the cutting regime. The appearance of coated plates, single layer or multilayer, determined the companies producing them to indicate information about the cutting parameters, but the values are given in a certain interval. In order to reduce the necessary experiments to indicate the optimal cutting regime, the paper proposes the analysis of the electrical current at cutting and its use for optimization. The processing of the experimental data obtained as well as the optimization of the cutting parameters was performed using Design Expert software.
