“…Experimental grinding was carried out on the ANCA mx7 tool grinding machine which had to be fitted with a special clamp system for the flat bars. [8], [ The next set of variables for these experiments are the grinding conditions. As there are many grinding conditions it was necessary to choose only those which have the biggest influence on the force and wheel wear.…”

Grinding is a technology which is used as a surface finishing operation. Therefore it is important for achieving good dimensions of accuracy. This accuracy can be affected by the size of wear of the grinding wheel. The size of the grinding wheel wear can be affected by the size of the grinding forces. Both of these factors can be influenced by the grinding parameters and the grinding wheel composition. Therefore, this article focuses on the influence of grinding parameters on the wear of grinding wheels and the size of the grinding forces when grinding VACO 180 maraging steel using SiC grinding wheels.

This article deals with the experimental grinding of cermet materials. Two types of cermet materials from different suppliers were ground under constant grinding conditions using a diamond grinding wheel. The main aim was to determine the influence of the grinding on the degradation of the grinding wheel and changes in the grinding process. Both types of cermet were ground with the same strategy and the same number of passes. The grinding wheel was analysed during grinding using an optical scanning device to observe the changes on the grinding wheel surface. Clogging and wear of the grinding wheel occurred on the surface as the amount of material removed increased. All grinding tests were carried out without dressing or truing of the grinding wheel. Degradation of the grinding wheel had a big influence on the grinding process in terms of the spindle load during grinding. The roughness of the ground surface was also measured using the optical scanning device. The results from this work will be used for further research of cermet grinding.

This paper is focused on research in the field of grinding VACO 180 tool steel. Different grinding conditions in terms of several cutting speeds and depths of cut were used for grinding tool steel with CBN grinding wheels. Two CBN grinding wheels with different grain sizes were used for several tests with the same grinding strategy. The influence of the cutting speed and depth of cut on the surface roughness was observed. The different behaviour of both grinding wheels was found during grinding in terms of achieved surface roughness. Higher grain size of the grinding wheel led to higher surface roughness, which increased with cutting speed. However, grinding with deeper cuts showed the opposite effect, and the surface roughness was better at higher cutting speeds. Lower grain size gave a more stable grinding process in terms of achieved surface roughness and lower influence of the cutting speed. However, greater wheel wear occurred during grinding with greater depth of cut. The grinding wheel was dressed before each test to ensure the same grinding ability. The results of this work will be used for a better understanding of the process of grinding tool steel.
