Abstract

Modern trends in technological development related to the use of numerical control machine tools are manifested by minimizing the number of technological operations, installations, operation elements. One of the most effective ways to improve the design of mechanical processing technologies is to create optimal technological dimensional structures. In the paper, optimality requirements are formulated in relation to the elementary dimensional structures and the entire structure. It is shown that a technological dimensional structure is optimal if it is similar to the constructive dimensional structure. Real constructive dimensional structures are very complex and varied, so that the optimality of some sequences of the structure excludes ensuring the optimality of other sequences. Reciprocal structural adaptations are required, which can be done by constructively resizing the equivalent part. As a criterion for the resizing, the non-admission of the increase in the tolerance of the machining allowance is manifested.
