In this paper we consider the question of the creation of optimal processes using a many criteria of optimality. In the synthesis of machining technologies must take into account a great many factors (economic, temporal, technical, dimensional accuracy etc.) that influence on the output quality parameters of the process and is not only essential but also quite complex in the definition. Among the criteria of optimality can be noted a minimum number of operations in the technological process, of technological mounting, of operation elements in each operation, of elements in the technological dimension chains; of a minimum values of machining allowances (a minimum values of allowance's tolerances) etc. Is shown the necessity of ranking optimality criteria, and that the first criteria to be considered are a criteria directly related to the accuracy of machining. In the synthesis of the technological process must be taken into account the results of the previous operation for the next operation. |
