Abstract 

Developed and researched mathematical model four-mass scheme autoclave machine tools. Influence of parameters of internal friction is analysed in the joints of structural elements machine-tool on relative amplitude of vibrations the cutter and detail. The ambiguousness of influence of parameters of damping energy of vibrations is shown on relative amplitude of the vibrations a cutter and detail.

Keywords 
self-oscillation
structural damping oscillations amplitude
frequency oscillations
the quality of the workpiece surface
the stability instrument.
