Study of the Axial Contact Points Method Applied When End-Milling Titanium Alloys

Vibration reduction methods were described. A comparative analysis of constructive and software methods was given, their advantages and disadvantages were identified. The results of the study of vibration reduction methods based on optimal axial cutting depths were presented. The axial cutting depth which corresponds to a certain pitch of the cutter spiral and a certain number of contact points was determined. The titanium alloy used in the aircraft construction industry was milled. Vibrations were measured in the frequency and time domains. Possibilities of stable cutting without reducing productivity were studied for a specific technological system. The nature of vibrations was analyzed at various ACP values. The hypothesis on the effect of the ACP on vibrations was confirmed. Cutting forces were measured. The ACP effect on the tangential, radial, and axial cutting forces was studied. The practical significance of the results for designing machining processes was shown. The monolithic carbide mill was used in the experiments. Its geometry was optimized for high-productivity titanium machining. When end-milling titanium alloys, productivity can be improved by stabilizing the cutting process. Directions for further research on high-productivity titanium milling were described.
