Opis:: This paper characterizes surface topographies produced by medium milling of EM AW-AlCu4MgSi(A) aluminium alloy in hardened state T451 using a ball-end cutter of 8 mm diameter and subsequent finish by roller burnishing using a Si3N4 nitride ceramic ball of 8mm diameter. It was revealed that ball burnishing operations performed on curvilinear milled surfaces allow obtaining the machined surfaces of high quality and exceptional smoothness with different textures and, as a result, ensuring demanded functional properties such as fatigue strength, bearing properties and contact strength [1]. It was experimentally verified that precision ball burnishing performed with a low stepover of 0.04mm produced a very smooth with the Sa roughness of about 0.02 µm characteristic for polishing.

Opis:: In recent years, metal additive manufacturing developed intensively and became a relevant technology in industrial production of highly complex and function integrated parts. However, almost all additively manufactured parts must be post-processed in order to fulfil geometric tolerances, surface quality demands and the desired functional properties. Thus, additive manufacturing actually means the implementation of additive-subtractive process chains. Starting with the most relevant additive processes (powder-based PBF-LB, LMD-p and wire-based WAAM and LMD-w/WLAM), considering intermediate process steps (heat treatment and shot peening) and ending up with post-processing material removal processes (with defined and undefined cutting edges), this paper gives an overview of recent research findings with respect to a comprehensive scientific investigation of influences and interactions within the additive-subtractive process chain. This includes both the macroscopic geometric scale and the microscopic scale of the material structure. Finally, conclusions and future perspectives are derived and discussed.

Opis:: The purpose of this research is to asses the functionality of surfaces produced by CBN hard turning, ball burnishing and superfinishing for improving the surface finish of parts made of high-strength, low alloy 41Cr4 steel with a hardness of about 57 HRC. Machined surfaces were characterized usin 3D scanning techniques. A set of 3D roughness parameters and real 3D surface topographies produced by the above-mentioned machining operations were estimated and determined.This investigation confirms that sequential processes based on initial CBN hard turning allows producing surfaces with better service properties.The main conclusion is that this sequential technology can partly eliminate grinding operations when hard machining is not enough to produce the desired surface finish.
