This allows the time intervals between dressing steps to be increased without compromising the accuracy of the grinding process, thus also increasing its productivity. It was shown that a model can be derived to design a gradient which reduces the wear depending on the local related material removal rate.

HIGH-QUALITY MATERIAL: Made of high manganese steel and brazed diamond, it's designed for long life. On the other hand, to evaluate the grinding performances of the V-tip wheel after truing, a micro-grinding test was also conducted on cemented carbide to grinding grooves.Chen B, Guo B, Zhao Q (2018) Online monitoring of truing arc-shaped diamond wheel by acoustic emission signal. Mao C, Zhou F, Hu Y et al (2019) Tribological behavior of cBN-WC-10Co composites for dry reciprocating sliding wear. This results in local deviations in the wear behaviour of the grinding wheel and thus, the grinding precision decreases with increasing wear. Due to the influence of the grain concentration on the grinding forces, a reduction of the force differences over the grinding wheel width compared to the concentration gradient can also be expected.

To analyse the influence of the gradients on the grinding layer surface topography, images are taken after processing. Subscribe to our newsletter and be among the first to find out about our latest product developments.The effects of discharge parameters, such as pulse frequency, duty cycle, and open-circuit voltage, on the shape accuracy of the V-tip diamond wheel were investigated. To analyse the radial wear of the grinding tools along the width of the abrasive layer the grinding wheel surface was measured by a confocal microscope of the type Confovis Duo Vario (confovis GmbH, Jena, Germany) at three points on the grinding wheel circumference. Therefore, a map of the grain size and grain concentration gradient in the grinding tools are necessary to evaluate the transitions between the discrete zones of area-related grain numbers. From this it can be deduced that the model can be used to design a uniformly wearing grinding tool for a pre-defined cutter geometry.

An analysis of the cutting edge chipping is done to evaluate the influence on the graded grinding wheels on the cutting edge quality. The first step is to calculate N A,i in the segment of the grinding wheel at which Q' W has its maximum.Yu J, He L, Huang S et al (2015) State-of-the-art of electrical discharge dressing technology for superabrasive grinding wheel. Ohmori H, Kasai T (1997) Development of metal-resin bonded diamond wheel for ELID-lap grinding and its grinding performance. Finally, the evaluation of the cutting edge quality is presented in chapter 5 and the summary and discussion in chapter 6. Zhao QL, Guo B (2011) Ultraprecision grinding technology of microstructured optical functional molds. The varying related material removal rate during deep grinding of cemented carbide end mill cutters results in an unevenly wear of the grinding wheel.

The model achieves wear levelling by adapting the area-related number of grains to the local related material removal rate.Uhlmann E, Schröer N (2016) Werkzeugschleifen mit Hybridschleifscheiben: Vergleich unterschiedlicher Schleifscheibenbindungsspezifikationen beim Nutentiefschliff von Hartmetall. On the other hand, it shows that a higher grain concentration reduces wear for the application considered. This leads to an increasing thermal load and, depending on the level of this, to increasing radial wear. This can be explained by not considering the influence of thermal load, which is difficult to simulate for flute grinding so far, or further geometric influencing factors.
