The Moscow Aviation Institute (MAI) has developed a methodology for the aviation industry to switch to Russian tools for processing parts made of titanium alloys. This was reported in the press service of the university.
Titanium alloys are among the strongest materials widely used in the aviation industry. However, their processing is lengthy and costly due to the high hardness and thermal resistance of the material. Therefore, we faced a task related not only to finding the most effective cutting tool within the import substitution program, but also to developing a new processing technique optimized according to the application area of the parts.
The customer will receive not only an accelerated manufacturing process for a specific part, but also a universal methodology that can be applied to optimize the processing of any other titanium products. The new approach will take into account such factors as chip thickness, entry into the workpiece, exit from cutting, milling of corners and pockets, as well as processing of thin-walled parts.
In the course of the work, the staff of the Department of Technological Design and Quality Management of MAI tested the tools of leading Russian manufacturers (Skif-M, Mion and Haltek), using special equipment with sensors to measure all key parameters - from cutting force to tool wear and the quality of the resulting surface. Based on the data obtained, they proposed changes, including options for effective cutting tools, adjustment of cutting modes and new processing paths, which in the future will allow the use of high-speed milling.
Currently, the pilot testing of the developed methodology has been completed at the MAI facilities, and the developers are writing a new control program for the machine, which will allow manufacturing the part using the optimized technology. In early autumn, it is planned to introduce the methodology and physical testing of the program directly at the production site of KnAAZ.
