SOLOKhA V. The precision vising of automated lathes by changing influence of joint conditions of base units on temperature deformations.

The thesis is devoted to the problems of research of the different factors influence on temperature displacements in the cutting zone of automated lathes, investigation of heat transmission through joints and the elucidation of the influence of contact surfaces macrogeometry on the joint heat resistance, the elucidation of the influence of contact heat conduction on temperature field and spindle headstock temperature displacements. The amendment at the head conduction calculation formulas of joint surfaces with macrodeflexions were introduced. The dependence of quantity and trend of spindle axis temperature displacements at joint plane on adopted scheme of being the fixed places elements and joint tightening was determined. Recommendations on minimization of the spindle headstock temperature displacements influence upon the machining accuracy were elaborated.
