“…The method for measuring wear indicators in the case of end mill cutters is more complicated than in the case of the turning process [38]. Various designations for these indicators can be found in the literature [12,17,39]. During the machining of polymer concrete, the most common wear type observed is abrasive wear on the tool flank of the end mill cutter.…”

“…The literature offers mostly information on turning [11,12] or grinding [13][14][15] mineral casts. The results of these tests, however, have no impact on the milling process due to the variability of the cutting edge loads occurring during this process.…”

“…The degree of the tool's wear is described by wear indicators, which are determined on the flank and face surfaces. These indicators are described in detail in works [12,17]. When the cutting properties of the edge are lost due to tool wear, 'dulling' occurs.…”

The paper examines the wear of end mill cutters, the parameters of a workpiece's surface layer and the values of cutting forces during the machining of polymer concrete, which is one of the most difficult-to-cut materials. Increased abrasive wear of the active cutting edges is a result of the heterogeneous structure of this material, and it has a negative effect on the cutting process, the durability of the cutting tools as well as the roughness of the workpiece. It is very important to determine the machining parameters for this material from a tool durability and quality of machining point of view. The research was divided into two stages. In the first stage, the appropriate machining parameters were determined based on the measurement of the components of the cutting force. In the second stage, durability tests of four end mill cutters were carried out. During the tests, the component cutting forces, tool wear and surface roughness were measured. The highest tool durability was recorded for the monolithic cemented carbide cutter with coating NC Mill G9F42120N 4F. Tools made of high-speed steel should not be used for machining polymer concrete, as they exhibited the highest intensity of tool wear. The rapid loss of machinability of these tools leads to a rapid increase in cutting force and the roughness of the machined surface. From an economic point of view, cemented carbide end mill cutters with coatings seem to be the appropriate choice for machining polymer concrete.

“…Machining is the most commonly used method of manufacturing components and parts in virtually all production technologies [18,20]. Machining operations use cutting fluids [2,23] to cool, lubricate and improve the surface condition of the machined part [22], to transport chips from the machining zone [3] and temporarily protect the product against corrosion [6,21]. In order to fulfil their tasks, cutting fluids must have a special chemical composition, which cannot adversely affect people or the environment [2,6,24].…”

The effect of the cutting fluid with zinc aspartate on the quality of the workpiece surface layer is reported. Until now, zinc aspartate has been used primarily in medicine and pharmacology. This paper compares the ecological cutting fluid containing zinc aspartate with a classic mineral oil-based coolant. Toxicity tests and a controlled process of tool wear during face turning were performed. Test results indicate that the use of zinc aspartate-based cutting fluids contributes to the reduction of the material roughness parameter values up to 35%, benefitting the final quality of the workpiece.

“…The treatment was carried out using plates made of cubic boron nitride (CBN) WNGA 060408 S01030A 7015. These plates gave the best results in preliminary research [20]. After the treatment, the surface roughness was measured as well as the maximum width of flank tool wear.…”

The paper presents the results of experimental determination of the Surface Geometrical Structure (SGS) parameters and tool wear during turning the polymer concrete. Until now, all literature reports have shown that the smoothness and roughness of the mineral cast surface was obtained directly from the mold. However, new applications of polymer concrete, even for some parts of the machine tools, forced the producers to carry out machining, which would improve the parameters of the surface layer. The topic of machining ceramic-based composite materials is a new chapter in the field of machining, which has not been sufficiently researched so far. The article describes the process of experimental determination of dependence of surface layer and tools wear parameters from cutting parameters during longitudinal turning of polymer concrete. The turning was carried out using plates made of a cubic boron nitride (CBN). After machining, the surface roughness and the maximum width of the flank wear were measured. On this basis, the mathematical model of the surface layer and tools wear parameters versus cutting parameters were defined. The authors also attempted to explain the phenomena occurring in the machining zone using variable cutting parameters. Microscopic pictures of CBN plates after machining were also performed. After the study, the final conclusions about the machining of mineral cast material were formulated.
