“…The increase in the pressure of the burnishing tool, under the same feed values, causes a decrease in the surface roughness of the shafts ( Figure 6 a). This conclusion is in agreement with the results of Dzierwa and Markopoulos [ 8 ] who machined 42CrMo4 steel surfaces and Shiou et al [ 49 ] who processed SUS420J2 stainless steel shafts. Plastic deformation is caused by the forces causing surface pressures exceeding the value of the yield stress of the processed material [ 10 ].…”

This article presents the results of tests aimed at determining the effect of slide burnishing parameters on the surface roughness of shafts made of 42CrMo4 heat-treatable steel. The burnishing process was carried out using tools with polycrystalline diamond and cemented carbide tips. Before burnishing, the samples were turned on a turning lathe to produce samples with an average surface roughness Ra = 2.6 µm. The investigations were carried out according to three-leveled Hartley's poly selective quasi D (PS/DS-P: Ha3) plan, which enables a regression equation in the form of a second-order polynomial to be defined. Artificial neural network models were also used to predict the roughness of the surface of the shafts after slide burnishing. The input parameters of the process that were taken into account included the values of pressure, burnishing speed and feed rate. Overall, the burnishing process examined leads to a reduction in the value of the surface roughness described by the Ra parameter. The artificial neural networks with the best regression statistics predicted an average surface roughness of the shafts with R2 = 0.987. The lowest root-mean-square error and mean absolute error were obtained with all the network structures analysed that were trained with the quasi Newton algorithm.

“…Tehát, ahogy az 1. ábra is szemlélteti, felületvasaláskor a felület érdességének csökkenését a megmunkálandó anyagnál jóval keményebb anyagú szerszám és a vasalandó felület csúszási súrlódásakor végbemenő kölcsönhatása eredményezi [5]. [12].…”

Jelen tanulmány alumíniumötvözeten végzett hideg képlékeny gyémántszerszámos felületvasalás véges elemes vizsgálatát tárgyalja, mely során bemenő paraméterként a vasalási erő, előtolás és sebesség értéke került meghatározásra, míg kimenő paraméterként a felületi érdesség változását analizáljuk. Ez az élettartamnövelő eljárás hatékonyan csökkenti az érdességet, javítja az alakhibát, illetve növeli a felületközeli réteg keménységét. A vasalást megelőző esztergált felület megmunkálási szimulációja a fizikailag megvalósult, mért értékeknek megfelelően történik DEFORM-2D szoftver alkalmazásával, annak érdekében, hogy a bekövetkező felületminőség-javulást számszerű értékekkel is validáljuk.

“…Tools for machining hard materials, for example, cutting inserts (CBN—cubic boron nitride, for machining hardened parts of up to 65 HRC) [19,20], are available in the market; however, obtaining the desired surface roughness parameters is not always possible. In this case, the surface can be improved by burnishing; however, this process has a different course than in case of burnishing soft materials [18,21,22,23,24]. The deformability of material is limited, and the smoothing of surface roughness occurs through material sliding, only within the roughness zone (there are generally no changes in the subsurface layer).…”

This article represents the results of testing the surface condition of shafts manufactured by the burnishing process. The shafts with a hardness of approximately 62 HRC (Rockwell C). were burnished with a ceramic ball (Si3N4), where the force range was controlled by the means of a hydraulic system. The machining process consisted of hard turning shafts with cubic boron nitride (CBN) inserts, followed by burnishing with the use of various machining parameters, such as feed and force. The research focused on the examination of burnished surfaces, which was conducted for various structures after hard turning, and with variable burnishing parameters. The results obtained for the decrease of roughness are presented as the relation between the parameters Rat/Rab, which is approximately 2, while for Rpkt/Rpkb, it is around 3.7, respectively. Sat/Sab is around 2, while Spkt/Spkb is around 3.5 (where an index denotes the t-surface after turning, and the index b-surface after burnishing). The structure of the surface after burnishing and turning is described with roughness parameters, as well as with the photographs of the specimen surface, and the bearing area curve.
