“…General results of the grinding process (surface roughness parameters, grinding power, and analysis of the GWAS cloggings after grinding) were described in one of the earlier works of the authors [33]. At this point, the results of detailed SEM-EDS analysis of the amorphous carbon impregnated active surface of 1-35 × 10 × 10-SG/F46G10VTO grinding wheel after the reciprocal internal cylindrical grinding of Titanium Grade 2 ® alloy were given.…”

“…The amorphous carbon, like the graphite, is characterized by low reactivity and authors proposed the use of this variety of coal as an impregnating substance. The conducted experimental studies, the results of which were published in the work of Nadolny et al [33], show that the use of amorphous carbon as an impregnating substance effectively impact on limitation of share of cloggings GWAS after grinding process of hard-to-cut materials. However, to determine the basic phenomena of physical and chemical nature that determine the obtained favorable effect, it was necessary to carry out detailed analysis of the composition of elements remaining after grinding on the GWAS.…”

In this article, we described a detailed analysis of the composition of elements remaining on the amorphous carbon-treated grinding wheel active surface (GWAS) after reciprocal internal cylindrical grinding of Titanium Grade 2 ® alloy. For this purpose, the scanning electron microscope (SEM) combined with energydispersive X-ray spectroscope (EDS) techniques were used. The SEM imaging and observation of selected fragments of active surface of 1-35 × 10 × 10-SG/ F46G10VTO grinding wheel was mainly carried out by use of two advanced microscopy systems: JSM-5500LV (JEOL Ltd., Tokyo, Japan) and Auriga ® (Carl Zeiss Microscopy GmbH, Jena, Germany). During EDS measurements, the Octane plus (EDAX, Inc., Mahwah, NJ, USA)-a high-accuracy silicon drift detector (SSI) was used. Conducted SEM-EDS analysis shows that applied impregnation method ensure the presence of impregnate in a grinding wheel body, also in subsequent work cycles of tool. Observed Ti cloggings on the GWAS appear solely on dulled vertices of active abrasive grains, which demonstrates the limited impact of the impregnate in the zone of direct contact between abrasive grains and machined workpiece surface. However, lack of extensive cloggings of the intergranular spaces indicating an effective removal of long ductile chips of Ti from grinding zone aided by the introduction of an amorphous carbon.

“…New types of crystalline ceramic binders have also been developed, which enable the regulation of intensity and rate of the wear and self-sharpening of tools [5][6][7]. There are also developed grinding wheels with micro-and macrodis-continuities of their active surfaces [9] as well as various impregnating agents preventing chip adhesion and bonding of tool surfaces [13,16,17].…”

Abstract: This article describes a case study of an application of the method of creating innovations called SCAMPER for the development of new abrasive tools designed for machining of hard-to-cut materials. The SCAMPER method is used for innovative transformations of existing products, aimed at a modernization of their design, a construction and an extension of functions. This method was used in the procedure of modifying abrasive tools and it permitted a generation of a set of innovative solutions in this field. The methodology made it also possible to logically organize individual creative activities supported by the previously accumulated theoretical and experimental knowledge.

The paper presents the results obtained for abrasive electro-discharge grinding (AEDG) of Ti6Al4V titanium alloy with the use of super hard grinding wheels of cubic boron nitride with a metal bond. The experimental investigations were focused on process monitoring for sharp and worn grinding wheels. For the evaluation of the grinding process, the grinding force amplitude and a few descriptors of the high-frequency stress waves were investigated in both time and frequency domains. The results show that during the AEDG, specific elastic waves are generated. Since these waves have characteristic amplitudes, frequencies, and other different descriptors dependent on the current grinding wheel cutting ability and discharge parameters, they can be applied to estimate a statistically significant regression function. For each measurement signal, a few statistical features are calculated and used as input for data selection and classification procedures. Registration and classification of forces and acoustic emission signals can be used to analyse the abrasive electro-discharge grinding process and allow for the determination of the machining results and the lifespan of super hard grinding wheels.
