The Influence of Diamond Burnishing Process Parameters on Surface Roughness of Low-Alloyed Aluminium Workpieces

Abstract

This study describes the determination and optimization of burnishing process parameters and their effects on surface roughness of EN AW-2011 aluminium alloy workpieces. The process has a low environmental load and the chip-free burnishing process improves the integrity of the machined surface, but to achieve this, the different burnishing parameters, for example, burnishing force, feed rate, speed and number of passes, must be properly defined according to the material of the workpiece. In our research, a full factorial experimental design method is used to plan and carry out the experiments and to determine the most appropriate parameter range for this material quality.

Az elméleti érdesség analitikus modellezése néhány jellegzetes gépipari megmunkáló eljárásnál

“…A gyémántvasalás, mint befejező megmunkálás már régóta alkalmazott eljárás a gépipari alkatrészek gyártásánál, mivel alkalmazása számos előnyös tulajdonságot nyújt. Ezek közül a legfontosabbak a felületi érdesség javulása (Ferencsik et al, 2022), valamint a képlékenyalakító technológiából adódó, a felület élettartamára kedvezően ható nyomó feszültségi állapot, illetve felületi felkeményedés kialakulása (Varga et al, 2018). A gyémántvasalás során az előzőleg valamilyen forgácsoló eljárással (pl.…”

Effect of Regular Shot Peening and Semi-Random Shot Peening Conditions on Selected Properties of the Surface Layer of Gray Cast Iron

“…In burnishing, the tool (e.g. a rotating roller or sliding spherical bowl) is pressed against the workpiece with an approximately constant force [5][6][7]. The effects of burnishing and shot peening can be assessed by both experimental testing and numerical modeling [8÷10].…”

Investigation of Face Milled Surface Topography on C45 Workpiece Assuming Movement at 30° and 60° to Feed Direction

“…There was a large increase in roughness due to the high rotation speed, thus the appearance of diffusion wear, as well as thermal softening and the increase in forming resistance. On burnished cylindrical surfaces, up to a third of Ra, Rq and Rz values were measured compared to the previous, turned topography if set to the appropriate values of burnishing force, feed and number of passes [10].…”
