The article presents examined properties of transformation of milling cutter shape-generating trajectories relative to work into parameters of the microrelief and the shape of the surface being formed in the milling operation. It is proved that geometric characteristics of the cutting tool, technological modes and features of the dynamics of the milling system have an effect on the formation of the surface. It testifies that: it is necessary to take into account independent processes in the chip formation zone unrelated to formability trajectories

The obtained analytical dependences, which allow determining the parameters of flank milling and peripheral milling using butt mills with various tooth cutters are presented. Computer simulation using these dependencies allows revealing of regularity in cut geometric parameters change, cutter force and friction load, as well as temperatures in the interface of the cutter tooth with facing and rough piece and also in the strand shell depending on the duration of the cutter tooth contact with the workpiece surface and the teeth distance

The paper presents a measurement package for evaluating vibrations of metal-cutting machines of milling system. It has been suggested to conduct an experimental study of the vibrational activity in end milling turning algorithms for converting oscillatory accelerations into vibrational displacements. In particular, it is shown that the values of random variables from such sequences contribute to the identification of stationary trajectories of rotary tool elastic deformation displacements against the workpiece.
