“…The aim of using machining processes is to produce surfaces with the required shape, dimensions, accuracy, and roughness, but when we select technologies and manufacturing processes, it is also advisable to consider development cycles; for example, environmental protection constantly requires us to develop materials and applied technologies in an environmentally compliant direction [4][5]. As burnishing is a chipless technology and does not require a high amount of coolant lubricant, it meets this requirement, but it also has several other benefits: it reduces surface roughness, increases surface micro-hardness, improves shape correctness, and causes compressive residual stress [6][7][8]. The compressive residual stress in the workpiece is advantageous from the point of view of fatigue.…”

The purpose of this paper is to present a comprehensive study of the stress state and hardening characteristics of low-alloyed aluminium cylindrical specimens subjected to the diamond burnishing process. Diamond burnishing has a surface hardening effect on structural steels. In the present study, our aim was to check whether this surface hardening effect is also observed for other (less hard) material grades, such as low-alloy aluminium. We also aimed to determine the technological parameters at which the greatest relative increase in hardness can be achieved by burnishing. In addition to the hardness test, the changes in the residual stress state due to burnishing were also analysed. Both hardness and residual stress tests were performed in two variants. Of the 4 technological parameters (burnishing speed, feed, burnishing force and number of passes), the burnishing speed was set to constant for one variant and number of passes was set to constant at the other variant, while two levels were chosen for the other parameters. A special formula was developed to determine the relative improvement in residual stress and hardness. Our experiments were performed using a full factorial experimental design. The results show that diamond burnishing has surface hardening effect and increases of residual stress on an aluminium alloy when applying adequate technological parameters.

“…A vasalás, mely eredetileg vasúti tengelyek megmunkálására kifejlesztett [1] befejező eljárás, ma már jelentős szerepet tölt be a hideg képlékeny alakító technológiák között. Az eljárásnak számos előnye van: csökkenti a felületi érdességet, növeli a mikro-keménységet, továbbá javítja a megmunkált darab feszültségállapotának jellemzőit, ráadásul nem igényli nagy mennyiségű hűtő-kenő folyadék alkalmazását, tehát gazdaságos és kis környezetterhelésű [2][3][4][5].…”

Jelen tanulmányban az élettartam-növelő felületszilárdító eljárások közé tartozó vasalás technológiájának vizsgálatával, az azzal kapcsolatos eredmények bemutatásával foglalkozunk. Analizáljuk, hogy a megmunkálás során beállított paraméterek (vasalási erő, előtolás, sebesség, járatszám) milyen hatással vannak a felületi mikro-keménységre, valamint a feszültségállapotra, illetve elemezzük a köztük lévő korrelációs kapcsolatokat. A kísérletek megtervezése és végrehajtása a teljes faktoriális kísérlettervezés módszerével történik.

“…By its application the surface roughness, the micro-hardness and the corrosion resistance can be increased, just as shape correctness of cylindrical surfaces can be improved [15,16]. In most cases diamond burnishing can be more effective than conventional chip removal finishing processes as grinding, lapping and polishing.…”

Abstract. In these days, diamond burnishing is frequently used for final finishing manufacturing operations of components. Diamond burnishing belongs to cold plastic manufacturing procedures. When using this technique, the following advantages can be obtained: micro-hardness of near surface layer is increasing; surface roughness is improving and the shape correctness is also improving. This paper deals with how the different technological parameters of burnishing, such as the feed rate, the burnishing speed and the burnishing force effect on the cylindricity of the burnished workpiece. The experiment was done on some specimen having outer cylindrical surfaces. The experiments were executed by the Taguchi type Full Factorial Experiment Design method with which empirical formulas can be efficiently created. The measurements of the cylindricity of specimens were done with a circular and position error measuring. From the measured data, special improvement ratios were calculated in order to define the appropriate range of technological parameters which results high improvements. Further aim was to compare the measured values of different cylindricity parameters.
