Special Issue Information

Dear Colleagues,

For tribology, the acquisition of information between friction surfaces, which change from moment to moment, is very important. In situ measurements can acquire crucial information on tribological phenomena and changes in their properties in real time. Along with advances in measurement and analysis technologies in recent years, the reality of previously unknown friction and wear phenomena is now well understood through in situ measurements. In addition, various novel methods of in situ measurements have also been developed and utilized.

In the Special Issue entitled "New Advances in In Situ Measurements of Friction and Wear Phenomena", original papers focusing on in situ measurements of tribological phenomena and properties from multifaceted viewpoints such as test methods, measurement methods, surface analysis methods, and data analysis methods are welcomed. Furthermore, the latest topics will be welcomed to aim for a deeper understanding of friction and wear phenomena in various tribomaterials and tribological systems through in situ measurements. Our hope is that this Special Issue will be utilized to achieve a breakthrough in realizing a sustainable society for the future. We look forward to receiving your submission.

In drilling small holes with diameters of 1 mm or less, minute clogging and twining of chips or the adhesion of the workpiece material can become factors in causing breakages of the drill bit; moreover, it can be difficult to identify the machining state. Acoustic emission (AE) sensing is a nondestructive inspection technique that measures the elastic-stress waves that are generated when a material is deformed and fractured. AE sensing permits highly sensitive measurements to be made without changing the rigidity of the experimental system, unlike force sensing of cutting resistance, etc. In the present study, attempts were made to identify the machining state and tool wear, and to predict abnormalities in small-diameter drilling by using the change in the frequency of AE signal waveforms arising from deformation and fracture. It was shown that it is possible to predict the breakage of the drill bit by detecting high-frequency AE signals at about 1 MHz, caused by the adhesion of the workpiece material. In addition, a correlation map of the AE frequency spectrum for identifying the machining state in a drilling operation is suggested. Full article
