“…It was found that smaller parameters did not mean lower surface roughness or waviness, and different optimum burnishing parameters could be got under different burnishing conditions. Luo et al [7] examined the effects of the burnishing parameters on the burnishing force and the surface microhardness with theoretical analysis and concluded that the burnishing feed and depth were the most significant factors. Luo et al [8] compared theoretical results with the experiments in which Al alloy LY12 was selected as material for making the specimens.…”

In this study, a simple roller burnishing tool was made to operate burnishing processes on A356/5%SiC metal matrix composite fabricated by electromagnetic stir casting under different parameters. The effects of burnishing speed, burnishing force and number of burnishing passes on the surface roughness and tribological properties were measured. Scanning electron microscopy (SEM) graphs of the machined surface with PCD (insert-10) tool and roller burnished surface with tungsten carbide (WC) roller were taken into consideration to observe the surface finish of metal matrix composites. The mechanical properties (tensile strength, hardness, ductility) of A356/5%SiC metal matrix composites were studied for both unburnished samples and burnished samples. The results revealed that the roller burnished samples of A356/ 5%SiC led to the improvement in tensile strength, hardness and ductility. In order to find out the effects of roller burnishing process parameters on the surface roughness of A356/ 5%SiC metal matrix composite, response surface methodology (RSM) (Box-Behnken design) was used and a prediction model was developed relevant to average surface roughness using experimental data. In the range of process parameters, the result shows that roller burnishing speed increases, and surface roughness decreases, but on the other hand roller burnishing force and number of passes increase, and surface roughness increases. Optimum values of burnishing speed (1.5 m/s), burnishing force (50 N) and number of passes (2) during roller burnishing of A356/5%SiC metal matrix composite to minimize the surface roughness (predicted 1.232 lm) have been found out. There was only 5.03% error in the experimental and modeled results of surface roughness.

“…Forgásszimmetrikus testek vasalásának megvalósítása során egy adott paraméterekkel rendelkező szerszám egyenes vonalú mozgást végezve végighalad a vasalandó, forgó mozgást végző munkadarab felületén. A hidegalakítás megvalósulásához szükséges nyomás a szerszám működő és a munkadarab alakítandó felülete közötti átfedés hatására jön létre [1], [4], ahogy azt az 1. ábra szemlélteti.…”

Jelen tanulmányban az élettartamnövelő felületszilárdító eljárások közé tartozó felületvasalás technológiájának vizsgálatával, bemutatásával, valamint ennek a megmunkálási módnak a hengerességre és felületi mikro-keménységre gyakorolt hatásának elemzésével foglalkozom 42CrMo4 jelölésű ötvözet esetén. Az egyes jellemzők méréséhez egy köralak- és helyzethiba mérő-, valamint egy Vickers keménységet meghatározó berendezést használtam fel annak bizonyítására, hogy a felületvasalás előnyösen alkalmazható ezen az anyagminőségen.

This paper presents the methods of experimental determining the depth of the plastically deformed top layer in the roller burnishing process. Precise determination of the depth of the plastically deformed layer is difficult due to slight deformation at the boundary of the plastic and elastic zone, the lack of visible changes in the microstructure, and minimal changes in microhardness. The article shows the method of original measurement method that consists in determining the thickness of the deformed layer using rings. The method involves the profilographometric measurements of the disconnected rings (samples) which are flat-faced in the package on the mandrel. The rings material deforms plastically in the surface layer causing wrapping of the end face of the ring in the direction of the rolling tool movement. After dismantling the ring pack, measurements were made on the face of each ring along radial directions, and the thickness of the deformed layer was observed on the microscope. The method was verified by microhardness measurements in the cross-section and cross-section of the ring. The results of deformation depth measurements were verified by finite-element-based numerical simulation.
