В статье представлена классификация по видам и характеристикам деталей основанная на разнообразии конструктивного исполнения изделия; выполнен анализ коэффициентов технологичности, к которым относятся коэффициенты стандартизации, унификации, повторяемости и типизации. Определена их связь с трудоёмкостью конструкторско-технологической подготовки производства и трудоёмкостью обработки деталей. Показаны недостатки рассмотренных коэффициентов.
In the paper there is presented a type and characteristic classification of parts based on the variety of product design fulfillment. The analysis of manufacturability coefficients is carried out to which belong coefficients of standardization, unification, repeatability and typification. Their tie with the labour-intensiveness of design-technological pre-production and labour-intensiveness of part machining is defined. There are shown drawbacks of the coefficients considered, for instances, in coefficients of standardization and unification one does not take into account different degrees of influence upon labour-intensiveness of constituents of these coefficients, besides, a repeated account of standard parts takes place. In the coefficients of typification and repeatability both variety of parts and their number in one group of items or one standard representative are not taken into account.
