“…Effective wear of the working electrode depended on many parameters of the EDM process, including open voltage, current amplitude, electrodes’ (tool and workpiece) material, and polarity. Regarding aluminum alloys, their low melting point, located in the range of 843–933 °K, adversely affected the wear of the working electrode [ 42 , 43 ].…”

Presented study concerns the issue of processing the AlSi10Mg aluminum alloy with a use of WEDM technology. Two types of samples tested during the experiment were previously produced in SLM and in casting processes. The aim of the research was to determine the dependence of the input parameters of SLM (laser scanning speed) and WEDM (current amplitude) processes on the performance of the WEDM process as well as on the roughness of the cut surfaces. The experiment was carried out on a specially prepared test stand, and the results’ analysis was carried out using the ANOVA (analysis of variance). A strong influence of the WEDM current on the process speed and on the Ra and Rz roughness parameters of the produced samples was found. The effect of SLM laser scanning speed was not so strong, but it tended to be uniform. On the other hand, the influence of the tested parameters on the WEDM process energy turned out to be insignificant and irregular. It was also found that for the WEDM process a sample made in SLM technology with relatively high laser scanning speed may be a better choice than the cast one. A case study was carried out to optimize the parameters of the tested processes.

“…Magnetic abrasive particles supplied to a workpiece are influenced by magnetic poles, thus forming a flexible magnetic abrasive brush. 41 Much development of this process took place in Japan in the late-1980s and 1990s. It was first proposed as an external finishing process for cylindrical objects by Shinmura et al 42 Research efforts have since established understanding of the process behaviour 43 and surface pattern generated.…”

The development of various nontraditional principles to finish the internal surfaces and passages is reviewed. In particular, attention is focused on three relatively mature finishing techniques: abrasive flow machining, internal magnetic abrasive finishing and fluidized bed machining. Their working principles, capabilities and limitations are evaluated accordingly. Finally, the significance of developing internal surface finishing capabilities and the vast potential ahead of this research field are highlighted.

“…Manufacturing industries demand efficient processes that provide a reduction in manufacturing costs and required time in order to gain competitiveness while meeting increasing quality standards. Thus, hybrid-manufacturing systems are becoming an industrial solution for the manufacture and repair of high-complexity parts aimed at various sectors [1]. The objective of developing hybrid processes is to enhance their individual advantages while minimizing their limitations [2].…”

Latest Developments in Industrial Hybrid Machine Tools that Combine Additive and Subtractive Operations

Hybrid machine tools combining additive and subtractive processes have arisen as a solution to increasing manufacture requirements, boosting the potentials of both technologies, while compensating and minimizing their limitations. Nevertheless, the idea of hybrid machines is relatively new and there is a notable lack of knowledge about the implications arisen from their in-practice use. Therefore, the main goal of the present paper is to fill the existing gap, giving an insight into the current advancements and pending tasks of hybrid machines both from an academic and industrial perspective. To that end, the technical-economical potentials and challenges emerging from their use are identified and critically discussed. In addition, the current situation and future perspectives of hybrid machines from the point of view of process planning, monitoring, and inspection are analyzed. On the one hand, it is found that hybrid machines enable a more efficient use of the resources available, as well as the production of previously unattainable complex parts. On the other hand, it is concluded that there are still some technological challenges derived from the interaction of additive and subtractive processes to be overcome (e.g., process planning, decision planning, use of cutting fluids, and need for a post-processing) before a full implantation of hybrid machines is fulfilled.
