Abstract
The features of milling of the difficult-to-process heat-resistant inconel 625 (analog of CrNi75MoNbTiAl) are viewed. The sample was obtained using the EBAM additive technology using an electron beam installation. By means high-precision analytical equipment, microstructure and physico-mechanical properties were studied on samples cut far and wide of feed path under synthesis. Acting cutting forces were measured under milling in various modes using a Kistler dynamometric turning appliance. The schemes for measuring cutting forces and their direction, depending on the contact conditions of the milling cutter and stock material were explained. Carbide end mills uncoated with diameters of 8 and 12 mm were used for milling. When measuring the cutting forces components, it was found that an increase in feed in the range of 25...200 mm/min during milling leads to a linear increase in cutting forces. At the same time, there is a stable tendency to exceed cutting forces when milling along the feed direction under synthesis in comparison with similar conditions. In the case of milling against the feed direction under sample synthesis, it was found that the specific cutting force in the limiting modes reaches values of 428 N/mm2. The analysis of the research results made it possible to develop technological recommendations on the assignment of cutting tool parameters and fixing limiting milling modes.
