“…Machining time, however, remains the main disadvantage of WEDM. Therefore, it is expected to be adopted in single and small-lot production [ 38 , 113 ]. Currently, wire electrical discharge machining is entering new industry sectors that were previously inaccessible.…”

This review article presents a summary of currently used and proposed methods of manufacturing fir tree slots of discs in turbine engines. The production of aircraft, including aircraft engines during times of overlapping global economic crises related to the COVID-19 pandemic or the war in Eastern Europe requires a quick response to the changing numbers of passengers and cargo. Similarly, the aviation industry must adapt to these conditions, and thus utilize flexible production methods allowing for a quick change in the design or type of a given part. Due to the constant adoption of new materials for the most critical aero engine parts and the necessity of complying with environmental regulations, it is necessary to search for new methods of manufacturing these parts, including fir tree slots. As an alternative to currently used expensive and energy-intensive broaching, many manufacturers try to implement creep feed grinding CFG or contour milling. However, other manufacturing methods, thus far rarely used for crucial machine parts such as WEDM, ECDM or AWJ, are gaining more and more popularity in the aviation industry. This article presents the advantages and shortcomings of these methods in the context of manufacturing fir tree slots.

The article presents and discusses a new method of grinding of magnesium alloys using conventional ceramic grinding. In this method the conditioning (cleaning) of the cutting surface of grinding wheel during grinding operation is applied. It will be shown that this method significantly increases the durability of cutting properties of grinding wheels. Moreover, the geometrical structure of surface layer of grinded workpieces in 3D configuration is assessed as well as manufactured, diamond like carbon coating on the surface is presented. Schlüsselwörter: Magnesium alloys / grinding / ceramic grinding wheels / surface geometrical structure / conditioning / wear resistant coatings Im Artikel wurde ein neues Verfahren zum Schleifen von Magnesiumlegierungen mit Hilfe von keramischen Schleifscheiben dargestellt. Bei dieser Methode wurde ein neues Verfahren zur Konditionierung der aktiven Oberfläche der Schleifscheibe (Reinigung) angewendet. Es zeigte sich, dass dieses Verfahren die Schnittkapazität von Schleifscheiben um ein Vielfaches erhöht. Zusätzlich wurde die geometrische Struktur der Oberfläche nach dem Schleifen im 3D-System bewertet und die darauf erzeugte diamantähnliche Schicht dargestellt.

“…Experimental analysis carried out to examine the significant factor in wire-EDM that led to the existence of thick recast layer with 5 to 9 μm thickness in Inconel superalloys [15]. Some findings concerning the effect of machining methods on surface morphology and stereo-metric surface parameters in wire-EDM of hard machined materials which also include Inconel alloys, are discussed [16]. Simultaneously, several studies can be reported in literature that discusses the challenges correlated with precision machining of different materials with wire-EDM [17].…”

In today’s competitive modern manufacturing sectors, there is a vital need of utter precision and rigorous processing using various manufacturing approaches that directly influences the cost and processing duration of mechanized materials in addition to the consistency of the finished products. Therefore, it’s essential to figure out the required output by adjusting the control factors of any machining techniques which resulted in optimal values of the desired outcome. In this study, machining evaluation and process optimization is carried out on volumetric extraction of material namely material removal rate (MRR), kerf obtained during the machining (KW) and surface roughness (SR) of Inconel 718 superalloy during CNC controlled wire- electrical discharge machining. Four controllable factors- pulse interval, wire speed, pulse duration and peak current are considered to investigate the influence on performance measures. Taguchi's L16 has been used to construct the set of experiments before physical experimental runs and most influencing factors have been evaluated using ANOVA. SEM images and EDXS analysis have been resorted to examine the morphology of Inconel 718. These findings assist in identifying the topography of the machined surface. Further, the optimum integration has been obtained for the best yield and recorded using grey relational analysis integrated with Taguchi’s technique (T-GRA). The unfamiliarity of the work is based on consideration of zinc coated thin wire electrode and Taguchi-Grey combined approach of modelling with four levels of experimental design.
