description: The master's dissertation is devoted to the study of methods of manufacturing fir-tree grooves in a turbine disk of a gas turbine engine compressor. In the course of this work, technological methods for the manufacture of grooves were considered and analyzed: the electroerosive method, the pulling method and the milling method. One of the tasks set in the work was to identify the most promising processing method. It was concluded that electroerosive machining is the most promising method for processing fir-tree grooves. The versatility and low cost of the tool, the processing of any conductive material - all these are indisputable advantages in comparison with traditional processing methods. But at the moment, electroerosive cannot replace traditional methods, including the milling method, due to the appearance of a secondary modified layer on the surface of the material. But in the future, this method has every chance to replace such traditional methods as broaching and milling, both in the conditions of large-scale, mass production, and in small-batch, one-off production. Due to the fact that electrical discharge machining has no chance at the moment to become the main technological method for processing such critical parts as the compressor turbine disc, and in particular, the processing of fir-tree grooves, the most developing method today is the milling method. In accordance with other objectives of the thesis, the issues of technological equipment of the milling method of processing were considered, the procedure for the design and manufacture of the necessary cutting tool (cutters) was considered, and a set of technological documentation was compiled.
