About this deal

mm of the grinding layer width is higher than the corresponding course of the related material removal rate. Zhao QL, Guo B (2011) Ultraprecision grinding technology of microstructured optical functional molds. The results revealed that the highest shape accuracy was obtained at pulse frequency of 4000 Hz, duty cycle of 50%, and open-circuit voltage of 25 V. Wegener K, Hoffmeister H-W, Karpuschewski B et al (2011) Conditioning and monitoring of grinding wheels. To calculate N A,i of the respective segment i, the grain size D i, the grain concentration C i, and the density of diamond has to be considered.

The limitation of the minimum manufacturable segment width leads to differences between the targeted number of grains and the number of grains in the segments of the produced grinding tool. Egashira K, Hosono S, Takemoto S, Masao Y (2011) Fabrication and cutting performance of cemented tungsten carbide micro-cutting tools. For the grain concentration gradient, the difference in grain concentration is at C45, while for the hybrid gradients, the differences are at C35, and C30, respectively. The properties of cemented carbides, such as high hardness, wear resistance and low ductility, lead to a high wear during grinding.

It was found that a reduction of the wear difference over the grinding wheel width of 52% and an improved cutting edge quality can be achieved by using graded grinding tools. To develop a model for wear levelling, the grinding tool must first be divided into a defined number of segments i. A cutting edge with less defects is important for the operational behaviour of the end mill cutters [ 3, 10].

The model achieves wear levelling by adapting the area-related number of grains to the local related material removal rate. Therefore, highly wear-resistant diamond grinding wheels are used for the processing of these materials [ 1, 2]. It can be assumed that there is a tipping point specific to the grinding wheel and the operation, from which too high a number of grains or too small abrasive grains increase wear instead of reducing it. However, an increase in grain concentration is limited by a bond system-dependent percolation threshold given through the reduction of grain retention by the bond due to a high abrasive grain volume fraction [ 15].Ceramic tile or stone finishes, whether natural or sintered, are the culmination and most visible part of any cladding job.

Apart from this, it also shows that a reduction of the wear difference is possible by adjusting the area-related number of grains to the local related material removal rate according to formula 4.
