Abstract

A theoretical analysis of the regularities of formation of machining errors, taking into account the uneven holes shoot allowance and education in the technological system of elastic movements. It is shown, that when drilling holes in consequence of participating in two opposed cutting blades drill is increased diameter of the hole on the magnitude of the elastic displacement. When boring holes in the emergence of the technological system of elastic displacement does not result in exceeding the diameter of the hole nominal value. This presupposes the fundamental difference between the conditions of formation of error handling when drilling and boring holes. Based on these dependencies ways were identified of improving the accuracy of holes
