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… Expand

The optimization of cutting parameters at turning, using electrical current at cutting, in order to increase the durability of the cutting tool
TLDR
The paper proposes the analysis of the electrical current at cutting and its use for optimization and the processing of the experimental data obtained as well as the optimization of the cutting parameters was performed using Design Expert software. Expand
A case study about acquisition of mechanically fixed cutting inserts
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 economicalExpand
