“…It is a direct result of improvements and developments of the technology over the last two decades in terms of surface quality and machining efficiency. For all those reasons, the use of WEDM for turbine disc manufacturing has been and is still the subject of research [ 24 , 41 , 114 , 115 , 116 , 117 , 118 ].…”

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 study aims to develop a neural network classification model to predict machining failures during wire electric discharge machining. Also, a process control algorithm retunes the process parameters based on remaining useful time before failure. In the proposed methodology, an artificial neural network (ANN) classifier receives four inprocess discharge characteristics as input. These extracted features are discharge energy, spark frequency, open spark ratio and short circuit ratio. Output classes are labelled normal machining, wire breakage, and spark absence. 108 experiments were conducted according to a full factorial design to train the classifier model, with 90 % classification accuracy. An ANN model was trained to predict the remaining useful time before failure, based on which process parameters are retuned to restore the machining stability. The algorithm was successful in ensuring continuous failure-free machining.

“…Rajmohan and Kumar (2017) performed the multivariable optimization of pulse timing, current, wire feed rate, tension in the wire and current for the improvements in surface finish, material removal rate and kerf width formed during the wire EDM of Duplex Stainless Steel (DSS). Conde et al (2018) analysed the wire EDM outcome by varying height of blank, dielectric pressure and pulse off duration for D2 Steels blank. Sahoo et al (2019) also optimized the main parameter for the enhancement in material removal rate, kerf width and surface finish during the wire EDM of high-carbon and high-chromium Steels.…”

Carbon Steel AISI 2010 is a general-purpose tool steel. It is the immense need of the industry to determine the optimal process parameters for the cutting of thick slabs of the metal using the wire cut, for the maximum material removal rate and minimum surface roughness and wire wear. Hence this research is designed to explore the influence of process parameters during the wire EDM of tapered Steel blanks. Tapered steel blanks with angles of 30°, 45° and 60° are machined and slots are generated in blanks using the wire EDM process. Taper angle, current and pulse-off time are considered the controllable process parameters for this study, whereas other controllable parameters are kept constant. Effect of these controllable parameters over kerf width, surface finish, MRR and wire are examined using the analysis of variance technique. Regression models for the four response variables are also developed, relating the variables with the varying controllable parameters. Multi-variable optimization of controllable parameters is performed using the Genetic Algorithm for the favourable response variables.
