Experimental studies are presented, were conducted that aimed at determining the mathematical models of the influence of the lead angle and the radius of curvature of the profile of machined sculptured surface on the components of the cutting force. The object of the experimental studies was a convex and concave surface of a turbine blade of Inconel 718 alloy. The toroid cutter was used for the tests. Based on the results of the study it was found that the lead angle in the machining of the convex surface and concave turbine blade should be continuously varied with the change of radius of curvature in the direction of the machined surface profile.

Presented is the own concept control method an lead angle axis of the toroidal cutter, depending on the radius of curvature of the machined sculptured surface profile. The method verified on the example machining of the turbine blade. In order to compare the effects of this method, to the classical method (without adaptation lead angle), tests were performed for both these methods.
