On the issue of accounting for technological heredity in the formation of properties of parts
Is considered the necessity of taking into account the regularities of inheritance of the part properties in the process of its manufacturing. It is shown that the main task solved at the stage of converting blanks into finished parts is not only to ensure the requirements of the working drawing, but also to take into account the laws of inheritance, therefore, it is nec-essary to conduct working off the details for manufacturability. Established the main fac-tors influencing the technological heredity at each stage of manufacturing of machine parts. It is shown that the calculation method does not allow us to isolate the most significant pa-rameter from the abundance of the consideration factors. In this connection, the process of stress inheritance is expedient to study experimentally. It is established that the technologi-cal processes of machining and assembling, which are developed taking into account tech-nological heredity, allow creating an appropriate technological regulation allowing to con-trol the course of changing the properties of the machined parts.
