Special Aspects of Forming Roughness on Turning Process of Variable Profile Parts

V.F. Pegashkin, L.V. Borshova, E.V. Pegashkina


The article is devoted to the study of the formation of voids in the surface when machining parts of variable profile. Shows that when working with a constant value of the actual filing of roughness is the same throughout the profile details. This makes it possible to get an identical roughness around the profile of all the party products that improves the aerodynamic properties of the product. Presented analytical solution of the task of determining the roughness of a surface of a detail of alternating along the length of the profile after turning cutting process puts you in control with a view to obtaining identical roughness. The mathematical models for determining the microroughnesses depending on the longitudinal feed for processing without control on the machine during processing and management. The results of the statistical analysis of the roughness profile surfaces of parts in production.
