The authors considered the problems of technological preparation of processing of blank parts of the machine non-rigid elements (FE) and proposed the methodology for specifying the mill modes with regard to the conditions of rigidity implemented through the definition of possible combinations of the cutting mode elements. The factors having the greatest impact on the elastic pressing of the workpiece elements during processing are determined. The authors developed and tested the experimental plant with the thin wall with the height equal to 15 and more of its thicknesses that allows processing the standard blank parts using the ultrasonic field energy in the cutting zone.

The experiments on the processing of VT6 titanium alloy with the subsequent assessment of the level of technological residual stresses (TRS) of a surface layer (PS) of the treated surface, as well as the changes in phase composition (PC) were carried out. The authors assessed the influence of the cutting mode elements on the technological residual stresses and phase composition when applying the ultrasonic field energy to the zone of formation of a surface layer of the non-rigid components surfaces and introduced the regression dependences for calculation of the cutting force components and the TRS level depending on the cutting mode elements.

The study determined that when developing NC codes of the advanced CNC machines, it is possible to implement the automated specifying of the mill conditions for the blank parts of the machine non-rigid elements considering the conditions of their toughness. The authors proved the efficacy of the technique comparing it with the results of CAE-analysis.   

The increase of feed per minute when milling VT6 titanium alloy blank parts causes the improvement of its performance characteristics (heat resistance) by means of the increase of β-titanium content; the applying of ultrasonic vibrations to the cutting zone causes the greater growth.
