“…Then, form grinding with conical wheels is conducted. In the end, finishing machining with form grinding wheels of a shape corresponding to the selected slot profile is performed [ 76 , 77 , 78 , 79 , 80 ]. In some cases, instead of roughing and form grinding, wire electrical discharge machining (WEDM) can be used for initial slot machining.…”

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.

“…These reasons led us to perform experimental research, the goal of which was to achieve significant progress in optimizing the quality of the machined surface while maintaining high productivity of the electrical discharge process. At the same time, we would like to contribute to the database of already existing knowledge through clear formulations of particular laws in relation to the processes that take place directly on the machined surface during the electrical discharge [ 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ].…”

When machining high-speed steels (HSS) with micro-wire electrical discharge machining (micro-WEDM), high surface quality is achieved as standard. The value of the roughness parameter Ra is less than 0.2 μm. However, the problem is the performance of the electroerosion process (MRR), which is low. This problem is related to the mechanical and physical properties of the HSS in combination with the setting of the main technological parameters (MTP). The proposed solution to eliminate this problem relies on the selection of proper procedures for the determination of optimization criteria in relation to Ra and MTP, with the inclusion of properties of the machined material. The solution consisted in the identification of four significant physical (ρ, κ) and mechanical (Rm, HRC) indicators of HSS properties, on the basis of which a suitable combination of the process output parameters Ra and MRR can be determined through established mathematical regression models using simulation and optimization. In the next step, the proper values of the MTP output process parameter settings, which correspond to the optimized output parameters Ra and MRR during machining of HSS by micro-WEDM technology, were then obtained by the same approach.

In the article, the authors present the concept of a mathematical model used to study the influence of the properties of the base materials used to produce an innovative abrasive wheel background on the operating characteristics of the final tool. This model will be used to verify various material and construction solutions. The article also covers the outcomes of research that confirm the developed model’s effectiveness in relation to the operation of lamellar grinding discs, as per their intended technological goal. The experiments involved surface grinding with grinding wheels constructed on chosen backgrounds. A dedicated research stand was designed to measure the temperature in the grinding zone without direct contact, using both new and used grinding discs. The tests incorporated various pressure levels applied by the grinding disc on the workpiece, as well as different working angles of the grinding disc.
