“…On the other hand, the maximum value of ccl is affected by the cutting speed v c , having a decreasing tendency with the increase of v c . The higher the cutting speed is, the higher the temperature gradient between the inner and outer chip faces becomes, leading to an intense chip bending and a simultaneous decreasing of ccl [13]. A further validation of the model was obtained by comparing the cutting temperatures calculated within the tool and the chip for an uncoated and a coated tool with corresponding temperature measurements in the steady state turning of AISI 4140 [14].…”

Based on analytical and experimental test methods, an evaluation of coated tools efficiency in milling Ti6Al4V with coated cemented carbide inserts is introduced. The stress-strain curves and the fatigue critical loads of the investigated coating were determined at various temperatures by nanoindentations and impact tests respectively, employing FEM-supported algorithms for results evaluation. The stress and temperature fields in the cutting wedge region were obtained by force measurements and FEM calculations of the milling process at various cutting conditions. A sufficient correlation of the coating's impact resistance at various temperatures with their cutting performance at corresponding cutting conditions is revealed.

“…Hard film prolongs cutting tool service life greatly, and improves cutter repeated usage rate. For the mould, hard film also plays an important role, because of its small binding coefficient [1]. It raises mould performance of anti-scuffing and precision of parts [2].…”

Bonding strength of the interface of film-substratum is an important factor and key problem that influence the reliability and usage of film-substratum system. The new technology of pulsed-laser shock detection method which analyzes the mechanism and mathematical model of film separation under the action of pulsed-laser shock,. With the example of measuring the adhesion strength of TiN/SKD11 film system, the surface was respectively impacted with pulsed-laser at the range of 650~1000mJ. To observe the surface topography of Impact points by scanning electron microscope, and to identify TiN film failure threshold by the reflected signal detection. By analyzing the experimental result, it was suggested that film/substrate interfacial adhesion strength was 4.954GW/cm2.

“…With this term we mean the useful life of the cutting tool, in time unites, from the beginning of the use of the cutting tool, until the time it reaches the predefined criterion of failure. The cutting tool life depends on the type of treatment, the type of the cutting tool (material, physical properties, coating and geometry of it) [2], the type of the treated material (constitution and properties), the way of mounting the cutting tool, the way of mounting the treated material, conditions of cutting (velocity, propulsion, depth of cutting) [3,4] and dynamic attitude of the system (machine -tool -material). In this research we examine the relation between the duration of life of the cutting tool and the material treated, we consider that all the other parameters are constant such as velocity of cutting Vc, propulsion per teeth fz, the radius and axial depth of cutting α, the lubricant used etc.…”

The usage of Computer Numerical Controlled Machines has been generalized over the last decades due to the increased demands for the production of mechanical parts with précised dimensions, higher production rates and products with better treated surface quality. It is well known that the duration of life of a cutting tool is one of the most important parameters during the cutting of metal parts, because it affects the cost of the manufacturing process substantially. Therefore, it is important to know accurately, the relation between the duration of life of the cutting tool and the conditions of the machinery such as cutting velocity, feed rate (fz), the depth of cut (radial and axial) etc. The purpose of this research is to conduct a proper number of cutting experiments in milling, measuring the wear of the cutting tools, in order to conclude in a mathematical model the wear cutting tool. This model can be implemented for the prediction of the cutting tool life, which is very important for the determination of the best cutting conditions. From the experimental diagrams we can come to conclusions for the course of the wear of the cutting tool in connection with the velocity of cutting, for the machinability of the materials used etc. The wear of the used cutting tools was determined by means of optical microscopy and stereoscopy.
